Well, 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 turn-on needs 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 denizens. 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 instant on.

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 lifetime.

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. -- Peace, bobJ

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 my basement 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.

Because:
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 output.
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.

Many fluorescents are dim in a 67F room. I have several in closets, and such, at home and a few of them here in the apartment. CFLs are worse.
