If it has a filament in it that heats up, you're fired!

Hi Lightbulb 1,
That is much better than Lightbulbman2008. Too ling, like ItisAJeepThing.
This is a great thread-forum.
RIGHT NOW, WE ARE TOTALLY USING COMPACT CFLs except for 4 round 60W incandescent bulbs, these frosted will always be installed above my wife's "Beauty"Mirror. WAITING FOR THESE CFLs TO DIE, THEN WE CAN REPLACE THEM WITH LEDs.
Hey lbm1, do you still have that antique incandescent bulb that I sent to you a few years back. I think that it was about 30 watts, it had a big looping filament and had been calibrated by the National Bureau of Standards. One side was flat and there was an X engraved on the other side. That way, it could be aimed directly at an experiment to deliver an ABSOLUTELY KNOWN AMOUNT OF LIGHT.
When we installed our first 12 Solar PV panels two years go, the company gave us about 75 CFLs of three wattage's, adjusted our AC and sealed our duct system. They charged about $1,500 per panel. AND wanted to make sure we noticed a big drop in our electric power bills. I's OK, but it couldn't keep up with the AC.
The next Solar PV system has 8 panels (they are actually more efficient). For THE PAST SEVEN MONTHS, our total electric bills stayed between $14 and $19 per month. These eight new panels cost about 1/2 as much as the first ones did. This will be the FIRST Summer with 20 panels. The QUESTION for this summer is, HOW well will the total system handle the AC when we have a long string of over 100°F days (high 70s at night).
OH, we just had an electric garage door opener installed. It has Two Lights, and the installer put in CFCs. HE SAID TO NEVER USE LEDs. Because they emit a radio frequency that could interfere with the Remote.

Hooray someone agrees that it's best to use CFL until they burn out, then swap with LED! Don't just make it someone else's problem! CFLs are not inefficient light generators, just a bit annoying if you don't work around the weaknesses.
However the RFI problem of LEDs is somewhat dated/misleading/incomplete. Old LEDs that have SMPS in them are indeed polluters. New DIMMABLE LEDs also tend to have SMPS in them are also RFI polluters. However the newer, non-dimmable, lightweight, cheapo LEDs should not have RFI problems. They're better than nondimmable CFLs by a long shot though still not as good as tungsten.
Dimmable CFLs are just as bad as dimmable LEDs, big RFI polluters. The same could also be said with a poorly designed incandescent system, too (phase control without line filters?)

quoting another: "...NEVER USE LEDs. Because they emit a radio frequency that could interfere with the Remote." What a crock! The circuitry in an LED serves only to drop the 120VAC mains down to a lower VDC to run the string of LEDs at a regulated current, which is a fairly quiet process. But that of the CFL is to boost up the voltage to the ignition point of the tube, many times 120VAC. First they rectify the AC to DC, then they run the DC through a chopper circuit to turn it back into AC (but at a much higher frequency so that tiny [read cheap] transformers for the step up can be used), then they apply it to the tube. As you can imagine, this is a relatively noisy process, not to mention the wide-band trash generated by any gas-discharge device like a CFL's tube. Methinks mister garage door mechanic is not intimately familiar with what goes on in the two. Switch out the CFL for an LED and then test your remote until your fingers blister. I'll bet you do not have a single failure. As another experiment, tune an AM radio to a dead spot between stations—where strong stations won't swamp out any RF trash it picks up—and listen to an LED and CFL individually as you turn them on an off. Which is loudest?

Actually most CFLs will "ignite" with 120VAC. It does convert to DC and then back to AC but doesn't need to increase the voltage any further...
It's best to just try it. I think most CFLs will work just fine though if you trigger the garage door safety switch, it will burn out the CFL fairly quickly...

The original 2007 law to "save energy" was a classic case of Big Government pretending to "do something" to solve a problem -- and creating new problems.
One example was the change to Daylight Savings Time that incurred a lot of costs to change over computer systems (I did a number of those myself) without saving any energy.
The banning of most incandescent bulbs was another. It forced upon us the only alternative available in 2012 -- CFLs -- which were considered as "hazardous" because of their mercury content. That, in and of itself, was inexcusable, but a classic example of Big Government interference.
A far better approach (if light bulbs needed to be improved for energy savings, which is at best debatable) would have been to tax bulbs deemed inefficient. Then the market would have worked its magic and come up with a solution buyers would buy -- like the far better LED bulbs.
(In the meantime, I'm still working my way through about 2 dozen 60 watt incandescents I bought up in 2012).

I should add -- CFLs are fine in some applications. I have a pair of them in outside lights that have worked flawlessly for going on 10 years. And in their enclosed lighting fixtures, they are unlikely to break.
But CFLs were never a good fit for ordinary household use, due the the mercury hazard.

How often do people break incandescent bulbs.
then the other questions...
How often do people break CFL bulbs.
And more...
How often do CFL bulbs break when they're installed in fixtures (versus portable lamps).
Then how often do CFLs break when they're in portable lamps.

One just burnt out a couple of days ago. I'm too lazy to get up there to change it, with all the heat and vog we're getting here, and the remaining bulbs give off enough light.
