Are these "instant ON" bulbs? Many from China have .5 to 1.0 second delay before light comes out after power on.

Yes, they are instant on. However, beware of their overall quality. I think I gave these a one-star rating. I bought around 8 of these in 2011, and half failed within 2 years. You won't get 25K hours out of any of these, for sure.

It's been my experience that these come on the instant the switch is thrown. There is no delay.

Yes, my bulbs were instant on. That is until one stopped coming on for good.

The first time I ordered this bulb a couple years ago they were instant on, and worked on a dimmer. Then I ordered more about a year ago, and they were horrible. They had the on delay you described, probably a bit longer. They would buzz and flicker in a dimmer circuit. I took one apart and the workmanship left a lot to be desired, not sure this thing is even safe to use. There was no listing mark of any kind (UL, CE etc) or manufacturer name anywhere on the bulb or package. Worthless Chinese junk!

Yes, they are "instant on", as soon as you switch the light on it is bright

I bought a box of 6 bulbs. One was not working from the very beginning. I installed two new bulbs and a starter, and it works now, but the noise is loud, and when I turn the switch on it gives a loud noise, which I didn't have before with old bulbs. My impression is that the quality of these bulbs is not good. Cheep price is not for free. I might be wrong. Good luck.

I'm pretty sure that the minimum increment of on or off time is one minute. The maximum on time is dependent on your bulb life.

from what I have read, it is a common problem with these lights. Mine lasted about a week and the company is of no help either. I tried emailing them and they said that they only sold the lights. They then directed me to a place in China so I just stopped there.

I have an older version of these bulbs, from 7 years ago. Mine take several minutes to reach a decent level of brightness, so it's good to hear that this has improved. On the plus side, I biught mine over 7 years ago, and they are still going.

Yes, as it works with a led lamp, it is "instant on". If there really is some delay, it's unnoticeable.

I dont know... I hooked them up to a timer but they are instant on so I don't know why the would not.Bob

These are standard spiral cfls. They are immediate on/off lights. I would have to say that they should probably work fine with a timer as I can't think of any reason that they would not. No, I haven't actually used them this way, but with my understanding of electricity and how it would work, I can't see any issues with it. The timer should do no more than open up the flow of electricity to the bulb when the timer turns on and then restricts the flow of electricity when the timer goes off, so there should be no issues with them whatsoever. I hope this helps.

To the eye, it appears that there is no delay at all. I have viewed the brakelights in the reflection of a storefront window via my own mirror and it appears instantaneous on the first illumination. As for the tenth of a second, get real; buy the bloody thing and you'll like it!

Yes, they turn on instantly. They aren't like the old ones that needed to warm up. As to the issue of temperature, I've never had a problem (and I live in Boston), but I don't use them outside. Hope this helps.

Yes there is a momentary delay. When they come on they are full brightness. They do not have to warm up.

They are not bad. I have had some 13 watts bulbs come on faster.. but it is not like it takes a minute before you see bright light. I do not know on cold weather. I have not tried these outside. I usually leave my outside cfl on 24/7 in cold weather, because they die out more quickly if you turn them off and on all the time in the cold.

All of the led transformers I have purchased seem to have a 1 to 2 second delay when powered on. I think this is a protection circuit. I have had a few of these on continuously for over a year with no blinking or any issues. good product

They are high / low. For me the life span was about 9 months. I dont think I touched the bulb when installing, but maybe I did. Pretty bright and good bulbs, but life wasn't there for me. I got Phillips Crystal Visions now and they are fairly close for less money.My Comparison from stock to These bulbs: http://carphotos3.cardomain.com/images/0015/46/98/15656489_large.jpg?v=1

This unit is solid state. No warm up time, Instant on. Don't understand the delay.

Just like someone else mentioned, they come on almost instantly (there's a fraction of a second delay), but it does take maybe 10 seconds or so before they reach their maximum brightness. The color of the light is definitely closer to that of an incandescent bulb than a lot of other fluorescents, but is still not exactly like the light that you'd get from an incandescent bulb.
