So what is the diff between this an costco? Costco seems like a better deal, but is it?
I picked up a set of the Feit lights from Costco and it's 2/3rds the size of this Defiant light. The zoom head on one of my lights has no friction and just free floats due to manufacturing defect. The Costco lights seems to have a more even zoom beam and the Defiant has a bright hot center spot in the beam. With the large reflector on the Defiant, I think it has more throw than the Costco.
