You snipped the entire question that I asked, then started disagreeing
with examples of why you'd want instant-on.
I'll put it back here:
got any data on power consumption vs time?
Does the incandescent stay on all the time?
If not, for how long?
Total power consumption in each mode?
If the incandescent part draws much current and stays on for very long,
it negates the power saving for light durations that are short...which is
why you'd want them anyway.
My point was intended to be...we already have CFL's that meet the
of ANYBODY. Problem is identifying them in the store.
I find the CFL's that take a second to do anything to be very disconcerting.
You flip the switch and nothing happens. Logically, you understand,
practically, it doesn't really matter,
but emotionally, my mind notices that something is not right and
starts diagnosing the problem. It's a double-take moment. I'm totally
disoriented for about a second.
I light my house with three 2W LED lamps that are on all the time.
I have one in the kitchen so I can warm up the coffee...
One in the bathroom so I can recycle the coffee...
One in the living room where I drink the coffee and joust with newsgroup
Life is good...
There are times when I turn on a CFL, but it's not a big percentage.
Ok, these measurements were taken with a cheap clamp on amp meter.
98 watts with halogen on at startup
halogen stays on for 50 seconds
30 watts after halogen shuts off
GE specs the bulb as 20 watts, I'm measuring 30 watts. Obviously I have
a measurement error. Power factor? I dunno.
Power factor of the CFL part is lousy. 20/30 is about right.
But thanks for the info. It proves my point.
If you have a lamp that's stays on a lot, the halogen part is of
little or no value to you.
If you have a lamp that is frequently switched on for a minute or less,
a lamp that takes 98 watts for a minute and has short life when switched
frequently and costs a LOT is of negative value to you.
You get the worst of both the halogen and the CFL.
Stated another way, the halogen/CFL combination is a marketing wet dream
designed to separate the gullible from their cash.
The best of the CHEAP "normal" CFL's work fine for all but the
persnickety with too much cash.
The questions have to do with power consumption, not why you want
instant-on. I figure they are a different concern.
Good questions about energy, but they do not address the question of
I think most every brand comes on now, but they may take 15 seconds to
get to full brightness. Some people complain about that, but in the
scheme of life, it is not a big deal. You can find you coat in the
closet and start to pee under less than full brightness.
I've experienced that with old bulbs too, but quickly got used to it.
I still have one fixture like that in a little used section of the
basement where the oil tank is. Probably will last another 15 years
as it is used once or twice a month.
I expect to change to LED sometime too, but I've not found the need
yet. It may be the best for my under counter kitchen light though. I
should look into it. LED is the light of the future, at least in our
Just to note that Consumer Reports tested this bulb and found that the
CFL part of the bulb failed *very* prematurely (less than half the
advertised life) if the light is turned off and on frequently.

Dang, you mean you can pee in less than a minute - WOW!
Maybe for some of us, the alleged savings in CFL
and the other drawbacks just
aren't worth it for many applications. I've tried them for example in
and the time it takes to get reasonable light just ain't
worth it. I could eat SPAM instead of steak to save a
few bucks. Should I do that too?
As for a closet light, it will be a long time before I
spend $7 on a light bulb where I use it for a few
mins a day, if that.
If you don't find fluorescent objectionable....
And it seems a bit odd to me to be going
to lights on 24/7 to cover up the defects with energy
saving lights as an effective way to save energy.
I have to admit I've done the same thing. For
example, I have some recessed CFLs in the kitchen.
Because they take so long to get any reasonable
light out of them, I now leave them on for hours
where before with incandscents I would turn them
on for a few mins. Now they are on from 5PM
until midnight. Probably using more energy than
before. Now that you made me think about it
I think I'll take em out.
A - I have yet to see a CFL that lights up instantly at 85%,
even at room temp.
B - I have yet to see a freaking CFL manufacturer that
even spec how long they take to put out say 75% of rated
They do say cute things like "instant on". Sure, they
come on instantly, but not much light comes out of
them when it's 30F for a long time.
