As a railroader, night work is a common occurrence. " Keep your head on a swivel" is a common phrase we use. Needing to know what's going on around you at all times, this is a great light for helping me accomplish that. Unfortunately it's not great for long distance (50yrds plus), but immediate surroundings, throwing switches, lacing air brakes and spotting customers, this light is perfect. As well as being seen. The battery life last me all 12 (twelve) hours. I'd recommend it.
