This is my first post and I am really excited to find a forum that is full of people who know WAY more than I do about electricity!
I am wiring up a lighting rig that will mount on my fire helmet. I am part of a great fire department and we are unhappy with what is available to provide us with light while we work. I have taken it upon myself as the station officer to figure out something that will work better for our crews.
My question is simple... I think... If I have an LED that the white paper says is rated at a peak milliamp of 20ma. and I hook it up to a 700ma battery will it overdrive the LED (burn it up) or will the led only draw 20ma? The voltage matches what the LED wants and what I am providing it. I just can't figure out if I have to add resistors to drop the millamps into the 20ma range or not.
thank you for your help!
