The specifications listed are for the first generation XM-L LED. The second generation XM-L LED will be 20% brighter while maintaining the same runtimes.
The Quark series offers a staggering array of options, accessories and interchangeability. With a wide range of LED, battery and clip choices, you get the features you want without compromise. Waterproof and constructed with aircraft-grade aluminum and impact-resistant lenses, Quark lights are tough enough to meet any challenge.
The QB2L-X has all of the same great features as the original QB2L and features CREE's new XM-L emitter! The XM-L is a slightly larger emitter, so the Turbo X received an updated, larger smooth reflector to maintain a great balance between light throw distance and spill area.
