Fast Fluorescent
 
I'm looking for a compact fluorescent light bulb that QUICKLY ramps up to full luminous intensity. The bulb would be used for a front porch light that is now attached to a motion sensor (thanks to replies to my previous post).

I'm currently using a 23W R40 FEIT CFL bulb. When powered on, this bulb will flash brightly for about 1/4 second, then lights very dimly. It takes about 20 seconds to get relatively bright, and about a minute to reach full brightness.

I would prefer a R40 type bulb for this application, but the recessed fixture I'm using could accept just about any size CFL bulb.

My main priority is something that lights and gets bright quickly.

Any suggestions???

I don't think flourescents in general can handle cold very well. Something about the mercury not vaporizing.
And if your motion sensor has a Triac and not a relay, it may not like powering the electronics for one of these lamps.

Thanks Yoyizit,

I'm in Southern California, so real 'cold' should not be a problem here. It was probably about 60 degrees last night when I was checking the ramp up time of my CFLs. Maybe not the ideal temperature for CFLs but not real cold either.

I think we had 20F last night.
Try it in other, indoor sockets?

Except for the bright flash, that's the same way my CFLs behave.

I've got the same lights indoors too. Same result even on warm evenings.

Possibly you could try LEDs but the light they throw off is directional.

LEDs? That would be cool, but they're still far too expensive.

Anyone else out there have CFLs that brighten up quickly? They've got to be out there somewhere!

I'd say if you need something to get bright quickly, just use an incandescent bulb. It will probably be your best option in this situation, other than using LED's (which you already stated are too expensive for ya).

Personally I hate using fluorescents; they have no place being in the living space of a house, but in my opinion are "OK" for like a workshop or garage. Problem is I live in a cold climate so the garage florescents have to be the "cold start" fixtures which are usually a little more expensive to buy.

CFs ramp up slowly, but standard ballasted fluorescents with a quick start ballast come up pretty quickly. They make the old-school "circle tube" style that can fit into some regular screw fixtures.

This might do what you need.
