I have found LED bulbs unacceptable in terms of directionality and intensity. there are certain applications I would probably find satisfactory performance, but as a whole I find LEDs lacking.

Eating tuna is going to poison you more than a lifetime of CFL's ever will.
It works out to be if you eat 1.5 cans of tuna a week, you will absorb just as much mercury in a year as you do if you were to absorb _all_ the mercury in one CFL. It's an amount about the size of a period.

In other words, nothing to even think about, really.

Just thought I'd mention I already put CFL's in my ceiling fans.
We'll see how it goes. (I think it's going to go a lot better than the incandescents I've been replacing in the past).

If I don't have to carry that step ladder into the house, and teeter on the top of it as often, I'll be one happy camper.

Oh, and the "mercury issue" really doesn't bother me much, but hey, that's just me.

Feel free to continue with the debate, but it's a done deal for me.
I'll let you know if I have to carry the ladder in again tomorrow. :D

I have CFL's in several enclosures, including two ceiling fans, and are going onto their 5th great year with not problems. The living room enclosure is probably around 2001 or 2002 install, and they still are going strong.

I suppose if you buy the real cheap ones, they'll die more quickly, so avoid the ones from the dollar store.

I have some Philips CFLs in my bathroom. They're 9W and are brighter than the 40W incandescents. The color is good. They're the 4" (I think) globe style. I got them at Walmart.

However, they take forever to warm up (I have to turn the light on at least 5 minutes before I go in the room) and one died very quickly. But they're the only globe type I've found that will fit in the fixture.

I just replaced the same kind a few days ago -- back yard, upside-down, and enclosed. It lasted about three years after about five hours a day.

considering CFL are MUCH cooler than regular bulbs I seriously doubt heat would be an issue if a 15W CFL is too hot for an enlcosure then a 60 W regular bulb certainly is. Mercury is so overblown. The CFLs out today have 1/500th the amount of mercury than the themometer your mom used to put in your mouth as a kid.

By the way they have CFL that are enclosed in a bulb to make it look like a regular bulb. So if overheating is an issue how coould they do that?
Overheating is definitely an issue... But not with the gas in the CFL, rather the ballast (electronic) portion which resides outside the fake "bulb" covering.

True,
But the amount of mercury released by using CFL is lower than the amount released by burning fossil fuels like coal to produce the energy to light them.
»www.energystar.gov/ia/partners/p···cury.pdf
PROVE that running a multi-10's-of-megawatt plant for the milliseconds it takes to power a single CFL for it's lifetime generates MORE mercury then is enclosed in said CFL - I don't believe it.

Don't reference any government websites either - they're the ones mandating the use of CFL's...
Those "milliseconds" quickly add up when there are millions or billions of CFLs replacing incandescent bulbs around the world. To think otherwise is foolish! With your logic, we might as well make every 60 watt bulb a 100 watt bulb since the energy production at plant level is negligible for one bulb!

This amounts to several hundred CFL bulbs around the property. I can say with much experience that if you can fit a CFL in where an incadesent was then go for it with no worries.

I have been doing so for 5 years. In this time I recall only replacing one of these for premature failure. (It had only a days use and quit)

There are still a significant number of original bulbs still in use around the hotel from when we opened five years ago.

Actually the most often needed reason to replace a bulb at the hotel is because someone stole it out of the lamp!!

I have had mixed results in using CFLs in an inverted position inside an enclosed fixture, some last, others wear out very quickly. Heat seems to shorten the lifespan of a CFL; then again some CFLs seem to have abnormally short life spans.

Just remember to properly dispose of any non-functional CFLs, people foolishly throw them out in the regular trash.

Is it because it's actually some sort of heat/fire hazard? (Or another reason?)

Or, is it just that they won't last as long?

I think it's a heat issue. Having said that, I have a 60W CFL (about 13W real-life) installed upside down in a jam-jar type bulb enclosure lighting the deck. I have it under photocell control and it comes on for 6-10 hours every day. It's been close to a year and still running great, so it's pretty much a luck of the draw thing.

If not, then I'm convinced (at least with my particular application), that it's worth a try.

In my Kitchen, I have a triple overhead light fixture with an open top,
I replaced the three bulbs with CFL's and it's incredible how much longer they've lasted. (They're still going).

By now, I would have replaced at least 6 or 7 incandescent bulbs.

It is enclosed AND upside down, and all CFLs i ever put in failed after a week or two - and they are only turned on for a minute or so per day (while we feed the dogs).. dont know if that's because it was enclosed or upside down.. or both.

FWIW we also put CLF's in the bathroom and are totally disappointed with the (lack of) brigtness & color. Although we did find that a mixture of "cold" light CLFs and a "warmer" light CFLs provide an acceptable mixture of color and brightness..]]> http://www.dslreports.com/forum/remark,22656990 Sun, 05 Jul 2009 12:47:40 EDT Re: Another CFL (compact fluorescent light) question http://www.dslreports.com/forum/remark,22656949 jadinolf : I have recessed fixtures in my hallway ceiling and some CFLs failed in the matter of a few weeks, Some have been in for years and have not failed.

I think that's it.

I have some enclosed lights that I put off using a CFL. But I eventually decided to give it a try. And they are working well, and I am not having to replace them as often.

I am still holding out on the recessed light over the kitchen sink. But perhaps I'll give that a try when the current incandescent bulb burns out.

Anyway, I'm wondering why there is a warning on some packages telling you to not install these in an enclosed fixture.

I have some high cathedral Ceiling Fans with an enclosed Globe light (the globe is maybe 6 to 8" in diameter), and it's a real PITA to change. (Have to get my tall step ladder in the house, and sway around on top of it while removing the globe and changing the bulb).

I'd love to put CFL's in them.
Is it because it's actually some sort of heat/fire hazard? (Or another reason?)

Or, is it just that they won't last as long?

If it's just because they won't last as long, it couldn't be any worse than the standard light bulbs I've been replacing all too often.

Thanks in advance for any info.
