Hi,
I'm an industrial designer - purely aesthetic, no electrical background (yet). I am working with a factory that doesn't seem to offer a lot of input on my lighting project, so I thought I would reach out to the CPF community.
I am building a small, high powered LED light that should run for 20 hours or more. It only needs to project 4 inches. Here's the 4 scenarios I'm looking at (below). Can you guys/girls give me an idea which would be the brightest, and approximately how long the LED will burn?
Honestly, I don't know if there are other factors that play a role, like resisters, type/size of LED, etc.
Thank you very much for your thoughts!
