I installed this light bar in about 20 minutes on my new Ranch Hand bull-nosed front bumper, after reading reviews and specs to be sure it would mount directly to the bumper light mounts with no adapters or brackets needed, and indeed the holes aligned perfectly. Some reviews have mentioned that the brackets arrived bent, and that they had to be bent to fit - partly true, but they didn't get bent in shipment, they were identical in their "slightly too narrow" aspect. This is intentional, so that when you slip them over the part that attaches to the light bar, it is held tightly in place as you stick the screws into their holes. So forget that whole "bent in shipment" thing, they are made that way on purpose.
Unfortunately, the bumper had big holes in the light mounting tabs, so I did have to go to Home Depot to get some big washers, so add 20 more minutes for that side trip. But that's not an issue with the light bar, more like an incompatible bumper that needed a little help to be securely affixed. Your bumper or mounting location may work just fine without any additional hardware.
I was having a new radio installed, so I had the radio installer at Best Buy pull the wires from the new Nilight dashboard switch ($10, also from Amazon) and connect it all up with soldered connections and heat shrink tubing like he did for the rest of the cables... That would have added a couple of hours if I had done the wiring myself - but since they had the dashboard apart anyway, this just made more sense to me. The zip ties in the photos were temporary until the wiring job was completed, now all wires are secured with black metal wire guides along the back sides of the bars. I did have to drill a hole in the bumper metal to route the wire - no big thing, and the Best Buy guys had a black grommet which fit perfect. Pros over there.
You have to have the LEDs on to align the light bar correctly - my best eyeball guesswork was making a big bright spot on the ground right about where the low beams hit the ground. Adjustment is simple, if you have the right screwdriver (varies depending on the bumper and mounting location, what all is in the way, etc). Alignment took 5 minutes or so. The light bar gets quite warm to the touch as expected, but at no point was it too hot to touch during the adjustment operation. Hot but not enough to burn you or be a hazard.
I very much like the arrangement of the 6 right and 6 left LEDs being flood focal length reflectors while all of the rest are long-throw spot focal length reflectors. You can see the difference in some of the pictures, and in those from other reviewers. You get a perfect mix of nearby and "way down the road" illumination. Check out the pictures and video - this thing looks great, works great, had excellent pricing for the performance, and is obscenely bright. Wow. Highly recommended!
