CF floodlight bulbs - experiences?

hrajotteDecember 23, 2009

I am considering Sylvania CF outdoor floodlight bulbs, 23 watts. I realize these bulbs function best in warmth, even though they are spec'd to start in temps as low as 0 degrees F.

I'd like to "go green" by saving energy, but good illumination is also important.

Can anyone share experiences, good or bad, with these, or comparable CF bulbs? Any recommendations or alternatives?

Currently, I have two 150W floodlight bulbs in a motion sensing fixture. With the low energy use of CF bulbs, I would install a dusk-to-dawn sensor instead. This would prevent the bulbs from frequent cycling, which I understand is not good for CF's.

TIA for any advice.

I sort of have a couple cheap ones from home depot in the 65 watt equivalent wattage ,,, seen to last forever. I know they're over 2 yrs old on a photo cell. Actually bought the R40 style indoor bulb.. replacing par38' cf's , hey they're under a eve.

Look inside the bulb its the standard twisted cf fluorescent in a glass wrapper with some silver paint for the reflector. My temps don't drop often below freezing but those bulbs always seem to start and work fine. That outer envelope keeps the heat enough to let the twisty bulb wall temp reach full brilliancy when it is cold and windy out.

Work just fine for me.

Try a couple. The biggest I've seen were 23 watt. I lit my backyard with them for a while but got tired of the 2-3 minute warm-up time and switched the fixtures out to one's that take a 26 watt pl type tube. The fixtures including the bulb ran about $40. If your's are dusk-to-dawn warm up is not a problem.
