Weltool T15 Elfin Flutist LED Tactical Flashlight ** Customer return. Cellophane has been removed from the box. Light is still in great condition. ** The T15 is a pen-style LED tactical flashlight that can be powered by two rechargeable 14500 lithium-ion batteries (1,400 lumens, 54,000 candela, 464-meter beam distance) or one 14/100 lithium-ion battery (1,100 lumens, 43,500 candela, 417-meter beam distance).
