I have a bunch of Hella H3 halogens on the back of my Dodge. Two outboard lamps are euro low beam projector headlamps for backing up quickly on ditchbanks. Then I have a pair of oval work lamps (two H3s in each lamp body) for broad coverage both laterally and vertically to pick up tree branches and such. They are all 55W (6x55W total) and are pendant mounted under the rear bumper but above the receiver hitch, never dragged or been hit. They work exceedingly well but draw a lot of current and get hot when the truck is not moving.
My Tundra has a pair of Ridgid Dually D2s flushmounted into the bumper. These are the ones with the diffusing lens to create a wide and tall beam without a hot center. Cost is probably about the same as the current price for the Hella setup on the Dodge, installation is a lot easier (as long as you are willing to cut holes in your bumper), and the installation is a lot cleaner and probably less vulnerable to damage than the Hella setup. Having said that, the halogens on the Dodge work a whole lot better.
My old GMC has a pair of no-name halogen rectangular work lights mounted under the bumper. I think they are H3s, probably 55W but I have had 100W in them in the past. They are old and ugly and cheap and they work just fine when they don't have mud on them.
If I were re-doing the Dodge now, I'd probably go with LEDs, but would be strongly inclined to flushmount two lights on each side of the bumper (four lights total). The Dually D2s were the brightest I could find when I did the Tundra, but I'm not getting the kind of useful pattern I wanted or expected. The Hella halogens work better, but there are more of them.
