Thanks to the Burst mode, a new feature for the QT2L-X, this light will hit a blazing 780 lumens of output for the first 60 seconds on the Max setting before ramping down over the next 30 seconds to 50% of the initial output. The Quark collection was designed to give you a staggering array of options, accessories, and interchangeability so that you have the right light for the job in any situation. With a waterproof, aircraft-grade aluminum body and impact-resistant lenses, these lights are tough enough to meet any challenge.
