Very useful - Competition Electronics Indoor Light

I resisted purchasing these, thinking I could improvise a homemade solution, or that the lights wouldn't work that well. After coming up with some ridiculous ideas and wasting a lot of time, I finally gave in and added these to an order. For recording velocities indoors, I don't think you could beat the ease of setup and use, and most importantly the ability to capture EVERY shot in varied light conditions. The only reason I withheld a star is that they only include a 110V wall adapter. It would have been nice and made a lot of sense to include a way to power them off of a 9V battery or two. They provide instructions for cutting the wires and rigging multiple batteries to get the correct voltage, which would ruin the wall plug and be anything but convenient. Still for basement, barn or garage use, I'd have to recommend these.
