I use110V work lights around the house but every second time I go to use one I manage to give it a little bump and the filament in the bulb goes. A real PITA. The last thing I need on the boat.
I learned the benefits of using a headlamp from backpacking in mountains. It's inexpensive, lightweight, compact, focuses the light directly on the object of your attention, frees up both hands and is very miserly on batteries. Most operate on 2-3 AAA and usually one change of batteries will last a season.
