From all I've read and seen on this light online the light output seems to be the same be it li-ion or nimh. Just the battery, weight, and charger difference is all. Nice light but I'd wait tillit drops a bit more in price before buying it.
http://www.beyondbikes.com seems to have the lowest price out there.
