The N30 is truly unique. We know of no other light that can offer this level of convenience, performance and runtime that's not twice the price. With it's removeable/swappable NiMh battery pack and 1+ hour runtime the N30 is much smaller and lighter than most other lights of comparable output - it's truly in a league of it's own. As bright as almost 50 3 D cell Maglites for about 1 hour!
