What I would like to see is a correctly engineer dual light. NR and everyone else seems to stack heads side by side. Most likely because of heat. I think the lights should on over the other, and off axis at 5 degrees. The low light would run all the time at 700-900 and the top light would have a reflector with more "throw" and run at 1000-1200. With appropriate remote switch - it could battery efficient as well.

Light all the time - power and throw -"down the road" when you need it - just like a car.
