EAGTAC S25L-R Base Flashlight XHP35 HI NW LED 1750lm Black. 2000 lumen LED. Bi-directional insert USB Type C plug for fast battery charging. Easy to use: rotate head to adjust 3 output levels tail-cap strobe. Smooth aluminum bezel. Waterwhite glass lens with harden treatment and anti-reflective (AR) coating on both sides (96percent transparency). HAIII hard anodized aerospace aluminum. Offer current regulated MAX output with a single li-ion battery down to 3.0V (underload). MAX output slowly reduces after 3.0V and operates until 2.65V (underload). Built-in shut down voltage at 2.65V (underload) to prevent over-discharge for unprotected li-ion battery (user may restart at lower levels). Active thermal management feature (adjustment range 75percent-100percent). Synchronous boost controller with ultra low resistance MOSFET which offers up to 95percent efficiency. High switching frequency convertor for more compact circuitry design. Non-dimming constant current regulation for all output levels without flickering. Zero standby current. LED direct soldering on copper for maximum heatsink ability. User replaceable glass lens. Battery reverse polarity protection. Ultra low internal resistance phosphor bronze springs (silver coated). Spring loaded positive and negative terminal. One piece head design for maximum heat transfer. Tailcap battery stabilizer design to prevent battery movement inside battery tube. Battery charging indicator. Built-in battery protection. Smooth aluminum reflector. Included Accessories: 18650 2600mAh li-ion battery (8A High discharge protection pcb built-in at anode).
