SureFire U2 Ultra flashlight

Compact (palm sized), high-intensity, variable-output LED flashlight for tactical, duty, and general use. Uses a virtually indestructible light emitting diode (LED) to provide six output levels, from a long-running low beam to a brilliant, white, tactical-level high beam with five times the light of a big two-D-cell flashlight. Ring selector provides instant output control. Electronic current regulation maintains a more consistent level of light output for the useable life of the batteries. Variable output, compact size, extended-runtime low beam and high-output beam capability, and 10-year battery shelf life make it perfect for backpacking, camping, or for disaster preparedness kits.
