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]

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.

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.

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.

[@massengineer7582]

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.

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.

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.

Richard, trouble adapting may be due to what you are used to seeing.

The reverse of this was actually cited as a reason to mandate the third brake light. Since it is JUST a brake light, it is an immediate and unambiguous signal of braking. Animated brake lights are a complicated solution to a problem that only exists because we, as a country, allow cosmetics to be more important than safety.

Possibly the most interesting video you've done. Had no clue about many of the things you explained, and I'm normally a very curious person. Been using mostly CFL lamps since the 1980's when the first good ones came out in Europe, which was a Philips with electronic starter, very small footprint and straight tubes, no more flickering starts as the first ones. Crazy expensive though. Was about $18 back then. Still got one from the late 80's, and it works. Have loads of Osrams from that era also from their best line, only one has died, despite being used a LOT, until LED got really good.

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.

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 almost every other location where you're going to leave it on for many minutes to hours? Why does it matter?

[@Kitteh.B]

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

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.

Perhaps, had they been sculpture vs functional, I would have thought them aesthetic.@@chitlitlah

Fun fact; some CFLs would say on their packaging that using them base-up would result in a 15% reduction in brightness, likely due to the cold spot being made hotter due to convection. Also, i believe GE wasn't the first to make such a "hybrid" CFL, I believe there was a Japanese lame manufacturer who made a similar kind of CFL back in the early to mid 2000s, but i'm not sure if they ever made it to the United States, or if they even caught on for that matter.

I have to be a pedant regarding your explanation of vapor pressure: in equilibrium, the liquid phase is still evaporating, but at the same time the vapor is condensing, so there is no net change. You can think of equilibrium like a game of chance where the odds are perfectly balanced, some molecules at the surface of the liquid are getting kicked out due to the random motion of atoms, and some of the molecules in the vapor just happen to bounce into the surface of the liquid just the right way to stick and become part of the liquid instead of bouncing off. When the average number of molecules / second leaving and entering the liquid are equal, you have equilibrium.
