I find I'm using lights less and less. Editing software like Final Cut Pro now has extremely powerful color correction tools, even when used with auto white balance. As soon as lights are turned on, natural animal behaviors stop. Shooting behaviors like cleaning, camouflage, and predation becomes far more difficult as soon as lights are turned on. Besides, they are only effective to a distance of 3 feet.
Currently I use lights only for macro, night dives, and dark overhead environments. Therefore they aren't a big issue with me. I'm happy with my hid's (warm, even light with a fairly wide beam). Considering that and the cost of upgrade, I'm not about to move to led's any time soon.
