Coast G30 LEDTorch (121 lum) Twist Focus, Blis. inc.2xAA. Harnessing the Pure Beam Optic with the ability to twist focus, the G30 Flashlight is a workhorse for daily use in a variety of distances. While in flood mode, the light casts a huge circle of light that is equally bright across without any dark spots. Then twist it into spot mode and the light will reach far downrange with a transition halo that allows for a large viewing area surrounding the tight spot beam.
