Review on EcoSmart Equivalent Daylight Energy Dimmable by Tara Williams

I would have given a better rating if one of the eight bulbs ordered at a time hadn't blown out in 6 (or less) months. The lamp in which the bulb was used has 3 cartridges. Two lamps from the previous set stopped working after a few years (which is normal) then I replaced them with these and they worked fine for about 6 months (which is not normal). This is not normal because I think the problem is clearly not in the lighting fixtures (the lamp is upside down, the light is directed downwards, the case is open and the other lamps have lasted more than a couple of years). "22.8 years (based on 3 hours per day)" means 2.9 years at 24 hours per day. We're definitely more than 3 hours a day, but a long way from 24 hours a day, so 6 months just doesn't fit no matter how I look at it.
