Flashlight’s Three LEDs Are Two Too Many

led-hs-pilot-3led-beam-sm.jpg When poorly aimed, a flashlight’s multiple light sources can create a serious Van Gogh effect! Doug Ritter writes about the clone flashlight that produced this hallucinogenic effect on his equipped to survive website, where he reviews outdoor gear and survival equipment. He writes:

“The “Pilot” lights by Holly Solar Products are a virtual clone of the original triple AA-cell Trek light, though of lower quality fit and finish, with a twist. Besides the Pilot 2 ($30) two-LED model, they also offer both a one- and a three-LED version. The single LED model, Pilot 1 ($20), didn’t seem to offer much except extra long life and it was quite bulky for the light provided. The Pilot-3 ($35) served as an excellent example of the difficulty that having multiple light sources that are not well aimed can cause, as it provided three distinct lit areas. Not too bad for finding your way, but seriously annoying when trying to use the light for close-up work.”

    I think this might have been designed for three eyed martians like in the classic colour War of the Worlds type movies! Though why not red green and blue led’s?

    So, did you establish a focal length for the 3 lights? Maybe they were mal-adjusted? Although your picture does look fairly even…
