No kidding... At work I replaced a whole batch of CFLs because they were growing dim after about 1 year. Now I change incandescents bi-weekly.

To high wattage or wrong type lamps in recessed fittings, poor ventilation and hence quick burn out of lamps.

Vibration of floor above the lamps

Poor connections causes voltage fluctuations, intermittand arcing and brief voltage spikes across arc gap.

too high continuous mains voltage 5% over 50% reduction in lamp life 10% over 90% reduction in lamplife

Sandro2,

What is the location of these fixtures? Kitchen, bath, porch, rec room? And what are the max wattage ratings for the trims? And are the trims listed for use in the housings? Give me something! Thanks, HLCbuild

Thanks
I will try these suggestions

also, you could put the lamps on a dimmer as a lamp dimmed to 90% should almost double the length of its life

D'oh! I didn't think about this before: if dimming isn't a necessity, try a compact fluorescent light (CFL). The use about 1/4 the power for a given amount of light, and less heat.

They come in both clear and frosted glass reflector bulbs, as well as standard and globe shapes, and even candelabra types.
