Elzetta Design's new High/Strobe Tailcap allows Elzetta 235-lumen LED flashlights to operate with either a constant 235-lumen high beam or with a high frequency strobe. On/Off is achieved with the pushbutton while High/Strobe mode selection is achieved by rotating the tailcap. Fully clockwise is constant-on, while unscrewing the tailcap anywhere from a few degrees to a quarter rotation engages the strobe feature. The mode can be changed whether the light is on or off and the tailcap draws zero current when switched off so it will not drain the batteries when the light is in storage.
