SureFire U2 Ultra High Intensity Variable Output LED Flashlight Review
SureFire U2 Ultra High Intensity Variable Output LED Flashlight Feature
The U2 is a compact (palm sized), high-intensity, variable-output LED flashlight for tactical, duty, and general use. It uses a virtually indestructible light emitting diode (LED) to provide six output levels, from a long-running low beam suitable for map reading, to a brilliant tactical-level high beam with five times the light of a big two-D-cell flashlight. The U2's selector ring provides instant output control, and electronic current regulation maintains a more consistent level of light output for the useable life of the batteries. At the high setting the U2 will put out two hours of tactical level light (50+ lumens from an LED source) with a total runtime of three hours. At the lowest setting it will run for 175 hours. The combination of features in the U2—compact size, extended runtime and high output capabilities, along with the 10-year shelf life of 123A batteries—make it perfect for backpacking, camping, or disaster preparedness kits.
