[ale] OT Just bought my 1st & 2nd "lighting-class" LED bulbs

[Ron Frazier (ALE)]

Hi Keith,

Thanks for that tip.  After reading your message, I went back and read all the fine print on the package, some of which is VERY fine.  However, they don't mention any such exclusions.  The don't recommend using these in wet or direct weather exposure applications (damp is ok), or in exit lights or emergency equipment.  Those are about the only limits.  Perhaps they solved the problem you mentioned with innovative heat sink design.  The fixture itself is rated for 100 W so, hopefully, everything will be OK.

Sincerely,

Ron
