Are you looking for a tail light or a headlight?
I'd like to experiment with one of the red LED flashlights on my commuting setup as a
taillight. I had read that they are 200 lumens, but those are the LED rating and not OTF lumens (and maybe I had read about the 50
2B instead of the 501B). According to mechBgon
in this thread, post #20, he described it as "the most intense red light I've ever had. If it were aimed precisely, it could be good to have in dense fog." I'm new to thinking about these LEDs, so forgive my ignorance in not knowing the 501B had been discontinued.

As far as I know they are the next model out where as the 501 is the previous model. I also have some diffuser lenses that are suppose to fit it on order. Also the 502 uses a Cree LED and depending on who's listing you read is rated between 140Lm and 210Lm so I'm figuring I should get an honest 100+Lm out of it.
I plan on posting my results once everything shows up in the mail and I get them mounted on the back of my bike.
Cool. I'd like to know how this works. They are about $17 on Amazon. Which lenses did you wind up purchasing?
