This range of General Purpose LED torches from Coast operate from simple AA or AAA batteries. The quality and purity of beam produced by their patented 'Pure Beam' Focusing Optic gives exceptionally pure, white beams without shadowing or imperfections. Coast torches with this feature offer long-distance beams when in 'Spot Mode' with a bright core and a wide peripheral halo resulting in a larger light area. When used in 'Flood Mode' the beam is approximately double that of most leading brands, with consistency and purity.
