| I have some CFLs in my collection, ie Philips Genie 11w, which when power is applied, gives off light immediately. Is this what is known as a cold start for the CFL lamp which causes more damage to the electrodes?
I also recently bought a new CFL from Asdas, a 20w GE BC Spiral CFL, this does the same thing when turned on. Pictures to come soon when I get my good digital camera back.

I actually found instant start CFL lasted longer than the slower start ones, the oldest Sprials I have are instant start! |

Yes each starting methods have their advantage - I like it how it starts up straight away, and doesn't take a second or two as it is indeed instant. |

| It depends on how the CFL is used. The instant start ones do well in places where the light will be on for a while, like a porch light that runs all night. The programmed start ones do well in places like a bathroom where the lights are switched on and off a lot.

uh Jeremiah, don't you remember how I explained and showed you my stuff, I tried those Sylvania "rapid start" CFL and other "rapid start CFL" (plus other deaf people I talked to told me about this too) on my alarm clock flasher and it kills them in a week, but since then, I started using instant start ones, and they still flash on me after 6 years! The programmed start don't do well since it takes too long to start them and is too late.... |

| Hey Jace, yes I do remember that, I did fail to mention the rapid start ones, those do indeed wear out faster than the instant start ones because the electrodes are kept in a cold cathode state too long as evidenced by the endglow being purple around the electrodes.
Yes, instant start is best in a deaf flasher because program start takes too long in that application and sometimes the lamp never lights up.
My previous post was referring to general use for a CFL, not a special case like a deaf flasher. For general, 1 being best 3 worst, 1. Programmed 2. Instant 3. Rapid. In a deaf flasher the instant start is the best choice.

I know this is kind of an old topic, but one of my CFLs (now dead) went from instant start to rapid start  I honestly don't know what happened there! does anyone else |

| I have had this happen too. It is probably due to the electrodes depleting to the point that they cannot instant-start anymore, so they do a rapid-start behaviour of lighting up dim with purple and brightening quickly.
As for instant-start, it seems that a lot of lamps made today use this starting method as it is more acceptable to the general lighting users who switch from incandescent and are too impatient to wait 2 seconds when switching on lights!
Of the lamps I have, all of the 11, 9 and 8 watt ones do instant or rapid start. But I do have some higher powered ones which are programmed start including a 20w GE spiral and (my favourite) a 12w Osram pear shaped lamp.

| rapid start is my favorite; they look cool when they come on. sadly, sylvania started using instant start ballasts in their cfls. the only way you can get a rapid start is if you use the light bulb base up. (which i do all the time!)

The future of street lighting is Induction, not nasty HPS lights or cr@ppy LED lights!
Preheat CFL's should make a comeback!

sylvania makes "instant - on" CFls , supposedly new technolgy but they work the same as regular- still have to warm up. http://ecom.mysylvania.com/sylvaniab2c/b2c/z_login.do this is a link to what the new instant on bulbs look like

Be careful, Dave the Silverliner told me most of the CFL fires has seemed to happen with the CFL that has been installed base up! |

| I have a very old Commercial Electric 9 watt spiral bulb which no longer instant starts, it flickers for about five seconds before starting. It used to be in my hallway and ran for about 3 years all day and all night (and now it is in my closet). I keep thinking that it is going to die soon but it has been doing this now for a couple months and just keeps on lighting up! And the ends are heavily blackened, but the darn thing just will not die!

Take pics or a video when it does die! I love watching CFLs die! |
