I also have an LED nightlight in the bathroom. Gives enough light
that you can use the bathroom during the night and not have to turn a
light on. Only had it about 6 months so I'm not sure how long it will
I have a 9 watt florescent tube fixture over the kitchen sink I leave
on, roommate can't leave it alone because his father who grew up during
THE Depression would beat him for leaving lights on. I don't bounce the
way I did when I was younger and I've been hurt because I tripped over
something in the dark. A broken hip costs more than the electricity to
run a 9 watt light 24/7 for 30 years. o_O
BUT if I needed to purchase some sort of light, any light, with the only
consideration being that it was going to go in an Edison base fixture, I
wouldn't even consider CFLs anymore. My choice today would be between
an incandescent and these new LEDs. The price difference between a CFL
and the LEDs (at $15, anyway) is little enough that I'm willing to pay
the extra for the luxury of not being annoyed at the CFL every time I
turn it on.

THe only place I have CFLs is in the unfinished basement, where
1) I don't care what how the light looks.
2) I don't care about the absurdly long warm-up. Much.
3) The lights may stay on for more than an hour a day so there might
be some energy to save.
4) Haven't gotten the T8s wired in yet.
#1 was resolved years ago. Current CFLs have good color temp and CRI.
#2 seems to only apply to encapsulated CFLs, not a single one of the
open spiral CFLs I've used has a warmup time over a second or so after
it's initial couple hours of burn-in.
#3 there is energy to save regardless of daily run time. If your sub
hour a day run time saves #0.03 that's still a savings. Total lamp
lifetime savings is still the same, it just takes longer to accumulate.
#4 I use all 4' T8 fixtures in my shop and I'm pretty happy with them.
LEDs would save more power, but it would take more fixtures to get the
same coverage as a cheap dual 4' T8 fixture.
Which ones? Subjectively, I don't like them, and objectively I haven't
seen any commonly available with CRIs listed significantly >80 (and most
don't list it at all)
The bigger the CFL the longer the warm up time it seems... which means
if you have an older house with older fixtures that were designed for
adequate lighting with 60W bulbs or greater then you'll be annoyed by
the warm up time. You're right, you can get a 13W CFL that isn't *too*
annoying, but if you need more power than that out of a single "bulb"
then the ramp up is back...
I guess where my frustration with CFLs stems from is a desire *not* to
replace old light fixtures with newer ones using fluorescent tubes or
multiple CFLs (what can I say, I like old stuff)
Yeah, T8 or T12 shop lights are hard to beat for illumination. The CRI
may not be the greatest but they're head and shoulders above CFLs in
lampholders for sheer illumination and the CRI is likely better too -
and 4' T8s are available in tons of different color temps etc. as for
years they've been the standard for commercial illumination. I ended up
using them in the whole basement of my last place; two troffers in the
"man cave" area that had a drop ceiling, and shop lights in the laundry

The 7.5W 40W equiv. LG lamps I've been using for about a year. I have
absolutely no issues with their light quality. They have two color temp
versions available also.
I use a bunch of higher power CFLs, the 23W+ versions. I put them in the
cheap clip on reflector fixtures and use them for work lights where I
used to use 500W halogen. I don't see any notable warmup times on those
unless I'm using them outside in really cold weather. I've also *gasp*
used 23W CFLs in enclosed fixtures with no meltdowns and still 4+ years
of service life.
The total light output isn't hard to replace with LEDs, but the light
distribution from a 4' two tube T8 is difficult to match.
None? Ever? I don't think it's necessarily that all spiral ones take
a considerable time to warm up, but I've sure seen plenty
of them that do take a long time. I have some of them in my garage.
right now. This time of year, they take about 1 min to get near
full brightness. For the first 15 secs, it's dim, but at least you
see. In the winter, you could double the time and for the first 30
you can't see worth a damn. They
are so bad, I switched back to regular bulbs for the most
critical of the 4, so at least I can see something.....
To be fair, these are older ones and I've had newer ones that
are better. But then when I bought these $7 things, they
were supposed to last a very long time so that I would get
the payback right? And one big problem that the industry
fails to address is that there are no STANDARDS. There
should be a spec system where how long they take to get
to say 50%, 75%, 100% output at 65F and 25F is right on the
box. That is one of the frustrations, that even today, you;re buying
pig in a poke. And what you bought last year, that gave an
acceptable light quality, warm-up time, etc, is probably no
longer available because now they have some other bulb,
from some other junk Chinese facility.
Oh and then there are other surprises. Like the CFL spiral
ones, at least some of them, say they are not supposed to
be installed upside down. Or the ones that look like reflector/
flood type bulbs. But while having basically the same shape,
the neck is much thicker so that it won't go into my recessed
The experience with CFL is one reason I'm not real quick
to jump on the LED bandwagon and buy all the marketing BS.
Not at $15 - $25 for sure.
If it lasts that long. Based on what I've seen with CFL versus
the claims, I'm skeptical. And just because the typical low power
LED indicator in a stereo or PC lasts a long time, doesn't mean
the LED light will. The light also has a power supply adn those
typically have things like caps in them that fail before the LED.
And with the drive to make these cheap so people will buy them,
I wouldn't be suprised to find out that the PS dies long before
the LED itself. And also, the light LEDs are high power devices,
so I don't think extrapolating the lifespan of an indicator LED is
Yep, they sure do. They also use T8 flouro arrays.
Yes, that's it, that's the ticket... Nobody could possibly have
experience that doesn't match your prejudice...
I've never used crappy CFLs, I used good CFLs and have now moved on to
good LEDs now that they are available at reasonable prices. The LG ones
I've been using for a bit over a year are performing wonderfully.
You really are an idiot. *YOU* just said that because you can't see
it, it can't happen. What a dummy!
All CFLs are crappy, in that you can't tell the difference between
shit and the best (still shit). You really have a *lot* of trust of
technology. Designing this stuff, I know better. LEDs are still at
least five years (probably ten, if ever) away from being useful for
