Description
U2-BK-WH
The U2 is a variable-output flashlight that provides six levels of light output. It uses a virtually indestructible power-regulated LED emitter and a precision micro-textured reflector to produce a consistently smooth beam at any level. A rotating selector ring just below the flashlight head provides no-look control of output levels: twist to change beam intensity from an ultra long-runtime 2-lumen low beam suitable for map reading, to intermediate-output beams, all the way to a brilliant 100-lumen high beam—five times the light of a big two-D-cell flashlight. Its pushbutton tailcap click switch provides secure, ergonomic activation control: press for momentary-on, press further to click constant-on.
