Well, to say I'm disappointed would be an understatement.
I put on a single 36W LED on the back to compare against the stock lights and tried then out tonight.
Not only was the output about the same as the stock light... but turning the lights on completely obliterated the radio signal. I've since read about some LED lights creating massive interference with radios. It is associated with the AC to DC conversion requirements associated with unshielded components. Apparently many less expensive or less well made, LEDs have unshielded components which cause this problem.

I'm sending these Nilight floods and 39 inch bar back. I've read that Cree bulbs don't have the same issues, so I'm going to give it a try. But, I'm VERY disappointed in the light output. I'd expected much more than my standard lights, but I think they are equal in output at best. Perhaps they are just cheap in all ways, but I'd espected more. I'd recommend staying away from Nilight brand as they don't step up to what I would expect given the stock halogens I have in comparison.
