Tonight I loaded a 35mm roll of J&C Classic 400 onto the reel in my darkroom. When I was almost finished loading I noticed the glow of the green LED on my electrical power strip. The light was under my counter and less than two feet from the end of the film which was dangling near the floor. I expected that the film was ruined, but developed and discovered that the negatives are normal with not a hint of fogging. I will cover the LED with some black electrical tape next time.
I do not recommend using green LED for a safelight, but I was lucky this time.
