With a remarkable peak output of 60,000 lumens, the Acebeam X70 Rechargeable LED Flashlight is up to any activity where bright light is required, from caving to search and rescue. Powered by a built-in rechargeable battery pack with eight high-drain 18650 cells, the X70 uses one Cree XHP35 HI and 12 Cree XHP70.2 LEDs to produce an exceptionally long, bright beam. It comes with a removable handle equipped with a cooling fan powered by its own 18650 battery (separate from the batteries that power the LEDs). The light can be used in either of two modes—Eco, with five brightness levels from 625 to 35,000 lumens, or Power, with five levels from 625 to 60,000 lumens. Both modes include a 10,000-lumen strobe for self-defense or signaling.
On/off and brightness level are controlled by a single push-button switch just below the light's head. The light and the cooling fan each have their own battery power indicator lights. The Type III anodized-aluminum housing is designed to withstand accidental immersion as deep as 33', though the X70 is not a dive light and should not be turned on or off underwater. Its prodigious output is efficiently conveyed by a smooth reflector and a tempered glass lens with an anti-reflective coating that delivers a 98.3% light transmission rate.
