Bests & Worsts Reviews from Amazon

I bought 5 of these and they arrived yesterday. I did a quick test when they arrived and then began setting them up today. While I was on a ladder rigging one of them, I gently moved the cord while it was plugged in and *POP*, a spark, and the breaker tripped. I promptly unplugged the cord, reset the breaker, and then took a look at the lights. Luckily I was using a fiberglass ladder or else this could have been an unhappy ending. Whoever built these didn't correctly strain relief the cords. In fact, all 5 lights have the wires exposed right around the strain relief. This means they ARE NOT waterproof and the slightest stress on the cord (moving it even), could cause you to be exposed to 110V AC! I don't know if the reviews are seeded by the manufacturer but I can't believe that no one else has noticed this issue.
