Its built well though somewhat cumbersome. AAA's in the headlamp assembly would be better. The incandescent portion of the lamp does an adequate job while the LED portion leaves something to be desired. The light provided by the LED's is white/blue and casts an odd hue. This is a good unit for close-up work or trail walking. Definitely not a good primary light source due to limits on brightness. Generally speaking, it would be nice if the industry standardized units to lumens in technical specifications of light models. Candlepower and wattage are misleading and confuse consumers.
