With five light levels, including Boost mode which provides 1200 lumens, the Lumina has flashing and solid options so you can choose based on the conditions at hand. The Collimator lens directs the light into a generously wide beam with even distribution to ensure that you can see upcoming obstacles. The OLED digital display provides battery percent as well as run time, eliminating the guesswork of how much time you have left, and the Lumina recharges quickly with Intellicharge moving the process along. NiteRider even gave this light a locking capability that prevents it from accidentally turning on in your pack or gear room--eliminating that awful moment when you're ready to ride and your light is surprisingly dead.
