Like Larry wrote, about a one second delay seems normal for these bulbs that are at room temperature, and a few minutes for full brightness. The delays are much less if the bulb was recently on.Installed several 60w (13w) ,2700k cfls. The problem is a long delay before the lamp illuminates! Air temp is 60 to 68 degrees F. anyone ever have a delay in these type lamps coming up or on?
Reminds me: I have a fan/light in my MBR that came with a remote and a dimmable thin circline fluorescent. The instructions recommend burning at full for 10 minutes before dimming, every time.They seem to dim pretty well for the most part, but when it gets a little cooler they often fail to come on at all when turned on.
Maybe it needs full power to strike the arc in the mercury vapor.I think that perhaps they do not like the ramp up function. But it is strange to me that they do not come on once the power is at 100%. I only notice this condition when it is cooler out (less than 40-50F).
They're not as bad as they used to be, but it's still long enough that I sometimes think the light isn't coming on when I hit the switch, and even flick it back off before the light comes on, until I'm used to it being a CFL.As Larry has suggested, I'm trying the 24 hour burn in time. Just have not had any cfl lamps with the delay in coming on!
I'm uncertain of my memory, but I believe they are properly dimmable with a special dimmer, not a standard inexpensive phase control dimmer. Lutron ... I think ... ???I have a lot of home automation dimmers in my house that ramp up and ramp down over two seconds when turned on/off. Knowing that most cheap CFLs are not dimmable...
I paid top dollar for a couple of CFLs that claimed to be "Dimmable".
These units were very expensive and only purchased because their claim was that were dimmable using standard phase fired dimmers.I'm uncertain of my memory, but I believe they are properly dimmable with a special dimmer, not a standard inexpensive phase control dimmer. Lutron ... I think ... ???
They are eventually given full power after the 2 second ramp up time.Maybe it needs full power to strike the arc in the mercury vapor.
Only you can say what you meant.Well, that's what I meant, wasn't it?
