How do LED bulbs function in temperature lower than 30 degrees F?
I am thinking of replacing the fluorescent tube lights in my unheated garage with LED’s. I have also seen LED’s that screw directly into an old fashioned incandescent fixture like all pre 1980 houses have in the garage, closets and basements. They are available at Home Depot for $19.95. However, they are only 60 watts equivalent light output.
I need at least 100 watts for the garage & basement.
I know I could replace the fluorescent tubes with low temp fluorescents like I had in my old house/garage.
A major factor in the lifespan of an LED bulb is its operating temperature. Unlike fluorescent sources, cold temperatures do not impact the performance of LEDs, though higher temperatures may.

I use 40 wa LEDs for outdoor lights in the Northeast - so far so good.
