Lugnut, what brand LED light did you mount outside? I don't mind paying the extra money for something of quality
I used Euri Lighting 4 ft. T8 LED Tubes - 2100 Lumens - 15W - 5000 Kelvin - 120-277V.
I installed them in PLT Solutions non-shunted, direct-wire, LED strip fixtures. Each fixture holds two 4 ft. T8's
At the time the tubes were $8.99 a piece and the fixtures were $12.99 each. That was five years ago. I'm sure prices have increased since then.
I ordered everything online from 1000 Bulbs in Texas. I got a dozen fixtures and twenty-four tubes. Shipping was salty.
I am very pleased with them. No problems in five-plus years. I can't tell you how many times I've smacked them moving the loft ladder around or flipping long work pieces (even though I purposely built high ceilings to avoid that). Those plastic tubes are durable!. Fluorescents would have given me a glass shower a dozen times.
As I mentioned in my other post, the outside lights don't seem to mind the temperature extremes.
