The unique build of the T1 encourages rapid heat dissipation by using proprietary unibody construction and precisely fitted LED modules.  Weltool's "Full Body Dissipation" technology passes the heat generated by the LED throughout the entire flashlight body instead of solely at the bezel.  This technology keeps the battery tube at a constant temperature for optimal performance, a true advantage in cold environments! 
    Safety is paramoount with reverse polarity protection and an anti-rolling designed body that give T1 tail-standing capability.  T1 is perfectly sized for the pocket as an EDC tool, and equally at home on the nightstand or in the emergency cabinet. With Black and Deep Red to choose from, it is the perfect choice as a gift for that special person.

Instructions:

• Turn the tailcap counter-clockwise to open, insert a high quality battery with the positive end towards the light bezel and tighten the tailcap by turning clockwise.
