CFL Bulbs Worry Me a Bit

[Code Doc]

Thanks, for the info, SH. I'll watch my 3-bulb fixture closely. It runs almost continuously at room temperature. If I notice any short life, I will notify you. These are 13-watt, soft white CFls, and they kick out beautiful light, shining through a plastic diffuser lens. Each is mounted horizontally and has about 2" clearance above and below the bulb. I have checked for heat and found practically nothing. Only a small, 1/16" crack between the lower cover and the case and a pair of 5/8" dia. holes in the top of the case allows for air circulation. These may be helping to keep things cool.

Regardless, I cannot imagine why you are having such a short bulb life.
