I'm not trying to sway you away from your decision, but I just got a couple of rigid d2s, and I just had to see how bright they were compared to my 6" 100watt offroad lights. I haven't done a definitive test yet, but, just with my rig parked in the garage, shining out, and holding one of the d2s in my hand, it looks like it is just as bright if not brighter!! I was shocked!!! Not only are they way smaller, they only draw 20watts of power each instead of 100watts each!! I think I m going to be removing my 6" lights altogether and simply replacing them with these smaller, more efficient lights.
Just saying, you might want to look into led.... They are amazing! No cheap, but well worth it in my opinion!
