Recommend a GOOD CFL

[Joe]

I'd like to purchase some CFLs that have light output and color
temperature very similar to a standard 100 Watt incandescent bulb.
Also, it would be best if it fits within the size envelope of a standard
100 Watt incandescent bulb, so that it will fit in some enclosed
fixtures.

Anyone have a specific CFL that fills the bill?

Thanks.

Any old CFL that fits the space, go up a notch in power and buy some
permanent felt tip pens and get colouring.

** They exist.

Look for 32 watt spirals in warm white.

Also, it would be best if it fits within the size envelope of a standard
100 Watt incandescent bulb, so that it will fit in some enclosed
fixtures.

** They do not exist.

High powered CFLs ( 22 watt rated or more) need good ventilation or they
fail rather quickly from over heating.

25 Watt warm white. I get mine at Home Depot (4 pack). Not Philips nor
GE brand.

I use the Home Despot-brand lamps. They're a little larger than a standard
bulb, though. But they're cheap and have a reasonable life span.

Just remeber, as I understand it, most CFL's are not made to be run
upside down.
I bought a Cree LED bulb 2700K color temp very similar to an
incandescent. 800 lumens, probably lower than a 100 watt incandescent.
Bought at Home Depot.

BULLSHIT! Most light bulbs are installed upside down, maybe you need a good
whack upside the head!!

So bulb down is the norm.

I thought it was just the opposite - and I surmised that the reason was
that the bulb was the heat source, and putting it ABOVE the base allowed
most of that heat to dissipate via convection.

Agreed.

Why would the tube heat up if it just holds fluorescing gas? The heat is
mostly in the case I betcha.

Nothing is 100% efficient.

I use a 5000K 100W-equivalent CFL in my bedroom, mounted upright. The bulb is
warm (though not remotely approaching "hot"). The base is cool, seemingly at
room temp.

That's what I thought also.

and I surmised that the reason was

that the bulb was the heat source, and putting it ABOVE the base allowed
most of that heat to dissipate via convection.

The CFL's are supposed to be long life, but those I use in my ceiling
fixtures with the base up, in a glass globe open on the down end seem
to fail sooner than expected. I think the heat collects in the globes
shortening the life.

Having some problems with civility there Shaun?
Or do you think you can convince people you are right,
by being aggressive in you response?
btw, you didn't convince me.

Whether CFLs have any particular issues being used base-up or
base-down seems to depend on the specific manufacturer.

According to one U.S. Government document I read yesterday, CFLs which
have the Energy Star labeling are required to work equally well in any
orientation, *unless* the manufacturer specifically labels them
otherwise.

Wouldn't surprise me if this isn't very well enforced, though. I've
had some fairly poor-lifetime results from some of the cheapie CFLs,
no matter what orientation we use them in. And, it's quite
disconcerting when their failure mode involves a hot base and
nasty-smelling smoke. :-(

Has anybody come across a good source for good LED-based ceiling
fixtures? Seems to me that the real "win" for LED lighting isn't in
"screw-in" replacement for existing incandescent bulbs (heat build-up,
less-than-wonderful light dispersion) but for ceiling-mountable
fixtures with a broader array of LEDs and a diffuser. This would
spread out the heat of the LEDs into a much larger
radiating/convection area and reduce the "bright points of light"
effect.

If I could find a nice-looking panel 18"-24" square, which could
radiate the equivalent of 5000+ lumens of warm-white (e.g. three
100-watt incandescent bulbs or more) I'd replace the old three-bulb
ceiling fixture in our family room like a shot. We've got CFLs in it,
but they're so bulky I had to remove the diffuser... doesn't look
wonderful.

Run a 26 W CFL in open air for 20 minutes and then grab the lamp.
The electronic ballast certainly DOES heat up, but the bulb itself
also gets quite warm. Some of them you can handle immediately, but
some get so hot you have to let them cool for a minute or two before
you can touch the glass. Even the 48" fluorescent tubes got warm, but
they had a lot of surface area.

Yes, this is why I made my own fixture. I just didn't see anything
that was suitable at a decent price. It was still pretty expensive
to buy 10 Cree LEDs and put together a constant current power supply.

To make a standard fluorescent replacement, I'd use 20 of these 1 W
LEDs, I think that is 4000 lumens, and use an off the shelf LED
power supply. That would run almost $60 total parts, but should run
a long time without maintenance. (I hope!) It should replace
two 48" tubes. I have the parts, just haven't getten around to
building it.

TCP is the company that manufactures CFls for American shops including
home Depot Walmart etc. There shold be no difference in private label
amongst the bigger shops as they are made in the same plant.

I'm not American so I could care less, but it looks like some of you are
so I will say this. Nobody makes CFL bulbs in America so don't look for
American made CFL, because they do no exist.

I'd been using them about two years before Consumer Reports rated them among
the best CFLs. I don't see how you could go wrong with them.

And if they did they would probably suck.
