Where did you buy those LED lights? Do they screw into a standard
socket? I have horses in a barn and have a 10watt CFL (equal to 40W)
security light which is on all the time (so the horses can see). I
guess 240W per day is not too bad on the electric bill, but the CFLs
get very dim in cold weather, and when our recent cold spell dropped
to MINUS 39F, it was so dim I could only see a dull glow, and then it
burned out. I replaced it, and it was so dim I could not see
anything. I finally replaced it with a smaller incandescent.

CFLs do generate SOME heat.

You might try enclosing the bulb in a clear glass fixture thereby trapping
some of the generated heat and increasing the light output.

Good suggestion, and I also wonder if using one of those shrouded CFLs
designed to be used in a canister or hi-hat application would last
longer as opposed to the ones that have the tubes exposed.
