Light & Motion ARC NiMH
This light comes with a 9 cell NiMH Battery giving it 3 hours runtime on the brighter 13.5watt/675 Lumens setting or 3.5hours if you drop it down to the 10watt/550Lumens level. This gives a enough light to head out for decent night ride and then it can be recharged in 3.5 hours with the turbo charger. The battery does come in a bit heavy at 660g but the light can be either handle bar mounted or our favourite the helmet mount system.
