Referring to Wikipedia as "this website I found" gets me every single time. It's just perfect.
So many people have an irrational hate boner for it.
as a decade long editor there, the description pleases me immensly.
Referring to CFL bulbs as "twisty bois" is what got me. I almost spat out my drink laughing.
Hey, it might be a really useful site! ;-)
But seriously, I'm so tired of people repeating what other people say about not using Wikipedia as a resource, as if they're incapable of deciding for themselves how good the information on any particular article is, and can't actually engage with any argument based on a Wikipedia article.
@macsnafu Wikipedia is contrary to the common buzz an excellent REsource, in spite of not being a reliable source in itself..
I have been a lighting consultant and owned my lighting supply for over 43 years and it’s been the energy laws that my state, California caused the country to eventually have to follow. In the beginning of the mandatory use of CFLs, dimming as not an option and one color temperature was how we got them. Slowly they added the colors but, as usual, each manufacturer had a different idea of what a 3000 Kelvin or a 2700 Kelvin so you could not mix manufacturer’s as you could see a color shift. We also had a lot of issues with screw in units when the socket had to be in the up position and then there were life expectancy issues when the lamp was used in an enclosed fixture and bad light output when used in exterior fixtures in cold environments. I, for 1 am glad we have moved on and we do sell an interesting LED replacement bulbs that fit the existing PL type fixtures but if you can, replace the fixture with a dedicated LED light source given that you can get more light, higher lumens per watt in a safer package and will last 35 to 50,000 hours compared to 20,000 hours and should be disposed of as hazardous waste. My 2 cents.
@fireltd2010 I mostly agree but I prefer fixtures where you can replace the bulb. If by dedicated LED light source you mean something that has non-replaceable bulbs, I wouldn't want to have to throw away the whole fixture if/when just a bulb fails. Even though they're supposed to last 50,000 hours, they're all made in China so I wouldn't be surprised if a lot of them fail prematurely.
In theory, yes, 50000 hours is what you may get from a modern LED. In practice, nearly all LED lighting is produced such that the diodes are constantly overdriven, thus drastically lowering their lifespan. The most notable exception are Dubai lamps (which use 2-3x less power for the same amount of light, go figure) and they are strictly made only for the Dubai market due to bribery from the sheikh.
Why would the light bulb manufacturers abandon the perfect product - unreliable, disposable light bulbs, for a perfect replacement? It is obvious, they are sabotaged to have a lifespan similar to tungsten bulbs while costing ten times more.
Yo dawg, I heard you like lightbulbs. So I put a lightbulb in your lightbulb, so you can light while you light.
Somebody had to say it.
nice april fool joke
You're the bulb now, dawg
Meme literally older than the lightbulb discussed here
@Konarcoffee Dated! 🤣
As a child I believed the slow turning on was the reason energy-saving lamps saved energy. We still have a lot CFLs in the house, because they won’t die. I was so happy, when one of the CFLs in the ceiling light in the bathroom died. I could finally install a LED bulb so the light actually turns on when pressing the switch and not five minutes later.
My parents told me that every time I complained about how shit they were. The worst part is they still have a bunch of the first generation in their house so when I go to visit in some rooms the lightswitch takes forever 🤦
Logical
My great aunt had vision problems in her house. I replaced all her lights with led last year. She can actually read her books again! CFLs are slow and full of mercury! Her electric bill is down by over half!
You can just replace them now. Its fine.
When this was an issue for me I just installed a single low-power incandescent and the rest were CFL so I would get some light immediately and then a lot of light in a few minutes
22:55 you must be talking to me. By the way, I do know that 5 deg F is the same as 6 months in metric units.
it's honestly annoying that the US still uses imperial. Like, come on, at least start the transition to metric.
Alec, have you considered covering ventilation as a topic? ERVs, bathroom and utility room fans vs in line duct fans, hood vents, etc? Air quality is on a lot of people's minds, and it would be cool if you covered all of the HVAC acronym!
This is also a possible side issue as talk is going around (to much consternation of the old fashioned set) about disincentivizing the gas stove due to the higher level of indoor air pollution it can generate compared to electric technologies. One obvious answer to this is better ventilation, but in order to avoid home heating energy waste needs to kick in only when needed for an operating gas stove. This should be a concern of kitchen remodelers and architects.
@SeekingTheLoveThatGodMeans7648could you imagine using a gas stove when it’s -30 outside if it required ventilation, depending on how much fresh air we’re talking the furnace might not be able to keep up at super low temps
Furnaces typically recirculate indoor air, they don't draw from outside. On a well sealed modern house you really get very little fresh air unless you open windows. It also drags down the efficiency of bathroom and hood vent fans because they're fighting the negative pressure they create in your house.
A very good idea now when you (not Scandinavian) people start to insulate. It's unnecessary to repeat our mistakes. Good insulation must be accompanied by sufficient ventilation - otherwise poor indoor air quality and mold forming...
@M_J_nan This is precisely the kind of thing I'd like to see Alec get into. Mainly the use of ERVs to be energy efficient while ventilating.
I'm convinced that Alec could make a 30 minute video about paint drying so interesting that I'd sit glued to my screen the entire time.
Best channel on YouTube.
You joke but there's interesting chemistry in that — evaporation of solvents but also polymerization reactions, sometimes with the air it's exposed to, possibly enhanced by catalysts which used to be toxic heavy metals but are usually less toxic now.
Brown paint's got some super interesting properties as it dries, since it has some hue changes as the different dyes react at different times. I'd gladly watch it.
Didn't he kinda do that with the whole Christmas light painting videos?
@charliesullivan4304 Dammit you have convinced us. We need a paint-drying video!
@jaredwilliams8621 I was thinking that too
My dad was an energy saving nerd. We still have some early CFLs in use, but everything was replaced with LEDs when they burned out. My dad used the very blue LEDs at first, but they have all since been replaced with soft white LEDs. Much better. I won't use anything but soft white LEDs in my own apartment.
The best LED's are the ones that are glass and have a nice slight warm tone.
@anymous4322what brand/bulb do you recommend?
@Mase32 I've had great luck with GE
>15 years ago
>2009
What are you talking about, 2009 was like 3 years ag... oh my god
My thoughts exactly 😞😞
crumbles to dust
god i feel old
I recently bought a used 2018 ThinkPad,
While the math may check out I refuse to believe it was made six years ago.
I bought my first CFL bulb in 1996 which was 28 years ago 👵🏻.
Mainly because I got fed up with the tungsten ones burning out.
CFLs starting out dim was a huge bonus for me, when I was a teenager my mom would wake me up in the morning by just opening the door and flipping the light switch on. Great way to start your day getting blinded as someone says "time for school". After replacing the lights in my room with CFLs I no longer got blinded first thing in the morning.
I really miss the slow start up in the bathroom, like mentioned in the video. It was great to be able to see that you were peeing all over the floor in your 3 am stupor without getting blinded by a full powered light.
@Luciano_Intorno I think it sucks that they don't really make low power leds for bathroom, no I don't want a 40W incandescent equivalent, I'd take 15W to not hurt myself. Thankfully there's a solution, battery-powered leds that are motion activated and give you just enough light and last a pretty long time.
I still have lamps with old, cheap CFLs connected to a digital appliance timer in my bedroom for that exact reason.
Seeing the "ground breaking light bulb from Phillips" brought back some serious memories, my father was an architectural advisor for a very wealthy neighborhood near me and these were all the rave. He would quite frequently take me on trips to see job sites and those boxes were everywhere! His passion turned me into an architect and I very much so remember these and feeling like they were foreign damn near alien lightbulbs when I was a kid!
love how so much R&D was poured into fluorescent lighting only for LEDs to just immediately become the singular best lighting technology, and for old style halogens to probably stay way more common due to cars
Well, I think a lot more R&D went into LEDs. Just look at how good the ones on the market today are
@brianfunt2619 It was enough r&d that the inventor of the blue led won a novel prize for it
Yea it’s kinda boring how often really clever engineering gets replaced by better material science,
"Singular best" is a stretch; personally I'm tired of every light source moving to LEDs, ESPECIALLY car headlights. There are trade-offs with any solution, like his "sodium lamp streetlight vs LED streetlight" video.
@cluverc4095 What is the matter with LED car headlights?
Glad you changed the thumbnail to say it wasn't an april fools, genuinely wouldn't have clicked on it otherwise.
I wish I'd noticed that.
Ah - growing up in central Queensland it was rare to notice the low light output at the start for CFL's due to the ambient temps for most of the year. The lower heat output coming from the desk lamp next to you was always appreciated though. My Dad was an early adopter of these when they appeared on this side of the world. Pity LEDs took so long, it was years after I saw their power consumption comparisons on a Mythbusters episode before I could even buy one LED bulb in a specialty lighting shop over here! Oh, and I'm with you on the "thumbs down" to red turn signals cancelling the brake light. "I'm slowing down so I can turn" is clearly understandable with separate brake lights and turn signal light.
Yeah we had CFL lamps with G23 sockets in the early 90s already, and 2G11 << these could optionally have a heater/quick start coil as they were intended for outdoor lighting.
The outer 2 pins were for the light-arc electrodes and the inner 2 pins would run the heater filament, the electronic ballast would heat the lamps as long as it's arc current did not reach a certain level.
As a seventy-one year old, I consider myself fairly technologically intelligent. I am a retired broadcast radio engineer which had to be a jack of all trades. But I always learn something new from your videos. Keep up the good work.
High 5
You must love all these CFL and LED videos with their cheap junk (mostly) switching power supplies which create enormous RF interference. You also surely know the FCC certification on this junk is only a manufacturer statement of compliance and nothing is or ever has been actually tested by the FCC.
GE R&D was developing one with a toroid in the center and exited the gas back in 1980. I saw the prototype. It didn't go anywhere.
@mikemandell132 In European countries we have CFLs which actually use proper EMI filters. I'm not sure about North America.
Alec, I recently replaced the taillights on my MK6 VW Jetta, and you'll be tickled to know I specifically bought new fixtures that have amber colored rear turn signals; thus righting a decade-long wrong.
In some Mk4 Golfs and Jettas and all Mk5 Passats I always thought it was so cool how VW made the entire lens red, yet the turn signal was amber when lit. Always impressed me!
nice april fool joke
In the part of the California vehicle code that sets basic equipment standards, amber turn signals on the rear of a vehicle are specifically forbidden. I looked it up when I was a cabbie and had come across a Crown Vic that had them, and so I wondered why all of them didn't.
Now somebody knows it's a turn signal The second it illuminates!
@taxirob2248 Is this an odd april fools joke, or just a mistake? Takes 2 seconds to check - amber or red is allowed at rear, amber or white at the front. California Vehicle Code 24953
One of the good things about this channel is there's no huge over-sized microphone taking up 1/3 the image, and the sound is recorded with just the right amount of natural souding room reverberation to sweeten the audio.
Your descriptions are always on a new level of meta-commentary.
Only comparatively.
I am commenting on your comment about meta-commentary.
I just want to point out that "fix[ing] the sometimes" is one of the most fundamentally satisfying things in life to me, and I wish we would focus on it more as a species
Dear TC, if i had the ability to erase memory, id erase my own of your videos, and then watch them and learn once again
Aggressive Amalgam is my favorite Math Metal band
Didn't they branch out into Chem Rock?
In the early 2000s, I swipped a CFL from a house I was leaving with 5 other tenants. It had a "globe" envelope, started very dim, and had a long warmup. The temperature was nice and low (I too am sensitive to clinically white interior illumination.) I used it as my bedside lamp for about 12 years, during which it came on in the morning when I woke up and burned all day until I went to bed. I still miss that bulb.
I wanted to take a moment of your time and say Thank You for all the years of informing and educating us. I have spent countless hours viewing your videos and it has impacted my life, "positively". THANK YOU.
"Unenclosed CFLs work great at room temperature"
"Oh, don't tell me you're dead. Well hold on then, I gotta get a different bulb"
They work great until they don't work at all.
I did the conversion of the 5°F for y'all: It's -15°C, 464° Rankine, 215.15 Kelvin, about -3°Rømer, -6.7°Newton, 180°Delisle, and -16°Réaumur
Edit: Whoopsie - 0x8badf00d caught me in a mistake; it's not 215,15 Kelvin, but 258,15 Kelvin!
+1000 for not putting a degree symbol alongside the K.
Should have had everything other than C
@ericw.1620the rest of the world aside from the us left the chat
I expected Celsius and Kelvin my good sir but you have outdone yourself. It's been years since I ever had to convert from those strangely inverted °Delisle.
❤ i love you 💓
My CFL died after something like 12 years of use. RIP trooper, I miss you.
“According to this web site I found”
I wonder where I could find a website like that ? It appears it could possibly be useful and one day may even be popular.
wikiledia? wikindedia? what was it again?
@gothicfan52It’s Wikifeet, trust me.
Funny every time 😆
@wheressteve It is hard to find these days, sometimes you have to get the 2nd page of google, past all the sponsored results.
As a kid I enjoyed the slow startup of the CFLs, especially in the winter mornings. My eyes had a chance to "wake up" and adjust to a brighter room more slowly.
Nice profile pic!
I personally find the instant on LEDs to be more favourable. My solution to lights being blinding is to have a weaker, easily accessible light in the room.
I agree there's a certain charm to CFLs.
I programmed my LED bedroom light to do this in the morning, precisely for that purpose😀
I use a dimmer. I turn it down as I'm winding down for bed because lower light helps me get ready to sleep and then when I wake up they are already low.
I enjoyed sitting in the bathroom doing my business when I suddenly I got this weird realization that it got brighter in the room. I loved watching our light sensing night light suddenly turn off after a minute of CFL warm up.
Am i the only one that likes the look of curly cfl bulbs? I wish they would make led bulbs that looked like curly cfl bulbs.
I liked the look, but they sucked in every other way. You could if you were a mad lad get a (broken?) CFL, blow,wash,suck? the phosphor out of the inside of it then string a flexible LED filament through it. You can buy them fairly cheap. You're going to want to lube the filament and the tube and use a pull string to get it in there but it'd work. Print up a new base for it or something with a power supply in it.
I always liked them. They look so whimsical!
They do! It's just kind of hard to search for them, for lack of knowing what to properly call them! They're not the brightest things in the world but I have at least one that is a clear glass spiral like a CFL, but it contains an LED strip.
no you are not the only one
They make LED replacements but they look ugly because when you turn them on you can see the individual chips, it's not a uniform glow like CFLs
"And they did it by taking this already lightbulb in a light bulb looking light bulb and going full turducken on it by stuffing an incandescent light bulb in the middle of the fluorescent light bulb inside of the faux light bulb"
THE WAY YOU SAY THIS IS EXACTLY WHY I WATCH YOU! (and maybe for the sciency stuff too lol).
I am totally stealing the phrase "full turducken" from this video. I will have a need for that phrase some day....
@grantstevens5 i work in hardware i bet I could find a use for it! Lol
I actually like the twirly bulbs,
they always just seemed more fun to me for no reason.
They are the crazy straw of the lighting world.
I never really though CFLs were ugly. I've always like the little spiral on them
Speaking of General Electric, did you know that they sometimes rebranded their fuses for a client? I've been volunteering on a 117 year old museum ship, and I found a bunch of fuses in the ship's ancient fuse panel. A lot of them are General Electric branded, but I found a few which were of the exact same model, but had one of two other types of alternate branding; one was a pair of diamonds with s's inside the diamonds, while the others were branded with a simple "C.P.R." - or Canadian Pacific Railway, the ships' original owner. Neat!
I don't know if it would be worth covering for an episode, but I thought it was neat to share.
Huh, sounds like the physical object version of white labeling, which I guess probably predates the software version I'm getting familiar with at work these days.
@gamemeister27 Physical objects definitely predate software white labeling. Lots of manufacturing companies (and chinese factories) will apply any branding you want to your order of product. This is why all these drop shipping stores are all selling the same things but with different brands. This is a very old practice.
@gamemeister27 I've done translations for a Chinese water bottle manufacturer and they do quite a bit of white labeling alongside their OEM business. In their case, white labeled products are designed by the manufacturer and customized by the client (mainly logo adjustments and CMF options) while the OEM bottles are designed and exclusively sold by the client. They sell some of their white labeled products under a few of their own brands.
A shocking amount of water bottles come from the same few factories, I'm guessing the same goes for many other daily items. That industry also has lots of copying, the specific manufacturer I worked for seems to market themselves as NOT copying others.
On a side note, Smart Water Bottles are apparantly a thing now for whatever reason.
@gamemeister27 I own an hardware store, and in my are is kind of the norm.
For secondary items, usually.
Like, a brand of "boutique" spanners offers hammers and tool boxes, too, to give full sets. But those low tech items are a generic hammer, painted in signature colour and branded to merge with the set.
If clients wants to have a matching color set, and pays premium for it, well...
@mtnentertainment3454Bicycles have been like that for ages - only a few manufacturers make most bicycles in China and Taiwan (Giant is one of them, who also make their own branded bikes). They'll build to your design, or they'll do the whole design & manufacture for you. Some of them make their very high end carbon fiber and boutique steel and/or aluminum frames in the US..
1:18 Not only do I remember that Philips bulb, I have one in service to this day. Sure it was a bit pricey, but it's in a location that is hard to get at. It's longevity and 'instant on' have made it's initial cost absolutely worthwhile.
My experience is pretty much the opposite, I had tons of those bulbs, but they had extremely short lifespans, way shorter than incandescent, and were ridiculously expensive. I did like the color rendering, but any hope of saving money over the long run vanished really quickly when I discovered how short their lifespan was.
I'd like to have one of those for historical purposes. I don't even like its ugly yellow beam; I just like what it meant for the lighting industry, the first LED bulb to win the L-Prize Competition. Plus, remote phosphors are really cool.
I have three of these, all still perfectly OK.
I remember the days when they cost 25x that of an incandescent but people still bought them for the energy savings
These generally tend to run pretty hot. I've had one catch fire in the last year... well producing smoke. It did not have a cover on in (upside down as an unprotected ceiling light).
I worked at Home Depot in the electrical department from 2005-2016. I remember every single bulb you showed, and the price point of the yellow Philips LED. Customers made fun of that Yellow Philips LED price and that bulb so much!
I absolutely loved the CFL for a bathroom lamp, it didn't blow your eyeballs out at 2am in the bathroom.
Why I just keep a fairly bright led nightlight on in there, it's like 3 watts. It's sufficient most times unless I really need the mirror for shaving.
A nightlight plugged into the outlet solves that problem too.
Then it dies after 1000 on/off cycles
@microwaveoven2 willing to accept that, can't buy a traditional bulb anyway.
walking through the bathroom just to take a dump at the middle of the night and all of the sudden you meet the gate of heaven
I received one of those “groundbreaking” yellow Phillips LED bulbs for free from a college recruiter event back in 2012. I still use it in my reading lamp and it’s still my favorite reading light. I’ve probably gotten much more than $60 worth of use out of it! Awesome product, and outlasted a few other led bulbs I’ve bought since then.
Most older LED bulbs had much higher quality drivers. Now alot of LED bulbs are cheap plastic and the drivers ussally die after a year
I used to work at a bank which had these extremely slow bulbs. It took about 5 minutes to get to full brightness. This video answers so many questions I had about them.
I still use CFLs in my bathroom for the very reason you mentioned. When you first turn on the light you're not blinded by bright light. It gives time for your eyes to adjust.
Dimmable LEDs are a thing. My GE Z-wave smart switches have a cool feature where if you hold the switch in the down position when the switch is off the light will come on at 1% instead of the last setting. It’s nice for those midnight runs to the kitchen.
As a nerd obsessed with plasma I will stick to my fluorescent lamps forever. LEDs are boring to me.
I have never seen a CFL take more than a second to reach full brightness. Of course, I live in Northern Australia, and have never experienced a night colder than about 6dC, so that might have something to do with it.
@mernokimuvekPretty sure LEDs still use Plasma. Just a much smaller amount of it.
@BabyMakR My CFL's take about 5 seconds to reach full brightness even at room temperature.
My parents used a standard CFL in the garage forever in a cold climate, I don't know if it was in any way useful how dim in started out but I definitely got used to it and expected it growing up. I was visiting over last christmas and flipped the light on one night and about fell down the steps it was so bright, like the view from the neighbors house in Christmas Vacation. Guess that old bulb finally bit the dust and got LED'd!
😂
I tend to accidently massively overspec LEDs when replacing CFLs, I keep underestimating the effect of age and the warm up do to their brightness. You'll definately be feeling it when I LED the house, my housemates can atest to that.
I replaced a CFL with one of those 3 way aimable LED units (from MENARDS!) in our garage and it's like Daylight in there.
Did I leave the Garage door open? Nope, light's on.
I had a CFL for my garage that I bought in 2001 that served me faithfully over 4 different houses before finally failing in 2021. 20 years of service. Felt like I'd lost an old friend.
I had tubes with old fashion ballast in my garage and they were totally useless below -10c. At least, CFL would eventually come around with enough patience.
It's great fun when you rant!
Greetings from Sweden, the country with snow half the year, and we never have problems with snow or ice on our street lights or car headlights...
Came for goofy light bulb, stayed for amazing science of cfl engineering!
Really neat video!
I never got the "CFL is ugly" thing. Then again, the amount of time I spend looking at light bulbs can be measured in the seconds putting it into the fitting, and pulling it out and throwing it in the bin.
I thought it was mostly about the light they put off. I was not as bothered by the cold, flat color fluorescents produce by default, but I can see the point. But I'm pretty sure they figured out other color temperatures eventually.
I like how you answered all the questions from the previous video that you weren't sure about
Heyyyy, I like the twisty boi look. Also there is something to be said about the engineering skill going into a device that had to twist molten glass into that spiral. Glass blowing of that level was probably incredibly expensive a few hundred years ago.
Props for the graceful and careful way you put the old bulb down at 1:40 such that it didn't make a noise. Here's hoping you got that with very few takes! 💡😁👍
Will say the slow glow CFL's make good wake up lights
Lol its wild to me to hear that dope looking spiral-shaped bulb being called "ugly." Never even occurred to me that someone could have preferred the look/shape of an incandescent lightbulb. Nor did the ~1 minute to full brightness ever bother me at all.
Those funny shaped bulbs are the dopest dope I ever smoked
Why would anyone think a helix is ugly compared to an egg? And the time to full brightness, it depends on where it is. In a closet where you're just going to turn it on, grab a shirt, and turn it off? It could be pretty annoying. In almost every other location where you're going to leave it on for many minutes to hours? Why does it matter?
No offense, but 'never occurred to you someone would prefer the look/shape of an incandescent'? There's a whole trend right now of "Edison-style LEDs" that use led strips in the shape of fancy filaments to mimic the color and look of old bulbs. It's been a thing for almost a decade
Well then you're a pretty isolated special case... 😅
I don't know why but I loved the clear incandescents, and the look of horribly inefficient dimmed bulbs. The helix just seemed like such a kludge. Take a hot tube, wrap it up in a sizzling hot ball, and then stick heat-sensitive components right on top of it. The engineering, I'll admit, spoiled my appreciation for them. Perhaps, had they been sculpture vs functional, I would have thought them aesthetic.@chitlitlah
Amalgam is a great word. Away back when if my dentist was doing a filling he would press an intercom button and say to his receptionist “prepare an amalgam please”.
the legs of his receptionist, amal?
@shaystern2453 are you from the 1920’s? Because no one has referred to legs as gams since then. Sounds like a line from an old Hollywood movie
@Quince828 Well, diälectal differences can be weird like that sometimes.
Ya, those amalgams ruined my teeth. Because amalgams don't stick to the thooth, the dentist has to undercut the fill spot. That means more of the tooth is ground away. Then, amalgams expand over time, like 10 years cracking the tooth. I had 8 molars done when I was 15 and in my mid 20s my teeth would hurt then i'd get a lung infection every 3 months and almost died.
@Blue-Maned_Hawk lol yup
@Tom025L - 2024-04-01
I've worked at GE on the development of this bulb. Dimming of the halogen capsule instead of a sharp turn-off was actually patented by a competitor who never released a product like this. Also, this lamp has just about the smallest room for the driver electronics of all CFLs, so an actual temperature compensation simply did not fit. There existed a different version with heater wire wrapped around the CFL tube instead of the halogen capsule, providing ca. 10-second runup without the light intensity and color changes.
@DennisKrger - 2024-04-01
Would a PTC really take up more space than a capacitor? I sounds even simpler than the cap, so I guess there's a good reason you skipped it, but it seems kinda obvious, even for the time.
@liryan - 2024-04-01
There you have it. A predatory patent ruins the day again
@TheVictorotciV - 2024-04-01
One of the reasons I love this channel is for comments like this. Where else would we have an insider perspective on topics like these?
Thank you for your comment!
@jsax01001010 - 2024-04-01
I was looking for the patent you mentioned as I'm always curious how companies manage to get patents on relatively simple concepts. In the process, I stumbled upon a patent from Osram Sylvania filed in 2005 for controlling, switching, and dimming a halogen bulb with a temperature compensation circuit, so it looks GE was out of luck with that idea too.
@technus6187 - 2024-04-01
See, as Alec was describing the vapor pressure issues with CFLs, my thought was, why not add another set of electrodes for a heater coil around the amalgam pellet, have it on at startup and then use a thermocouple to determine when the tube is at operating temperature and switch it off?
