Time to upgrade the 'light bar' in the bathroom. Bathroom on/off frequency is hell on CFL. This should turn a 6 bulb light bar into approximately the same light output as a single 250W incandescent bulb for 36w of power draw. I seriously doubt they will last the ~7 years@ 8hrs/day advertised, but we'll see.
I don't know about these, I got in on a deal with for the Phillips 60watt comparable 12.5watt LED bulb and I must say it is wonderful, the light is soft and clean, no CFL flicker and i swear it is brighter than a 60watt incandescent bulb.
Not sure about these 40watt bulbs though, since Shoprunner returns are free I think Im in for 2 to test them out.
