The Fenix UC52 features a Quad Core Cree XHP70 LED with a maximum output of 3100 lumens and is rechargeable via Micro USB. A built in 7.2V 3500mAh Li-ion battery pack means there is no need to purchase batteries or a charger as everything required  is inside the box.

A unique feature of the UC52 is it's OLED screen, which displays the selected output level and remaining runtime so users know in advance when it's time to recharge. When the light is switched off a single click on the auxilary switch will display the battery level as a percentage. Thanks to the USB charging the UC52 can be charged via a power bank when travelling, or inside a vehicle.

Operated via dual side switch for easy one handed use. The master switch controls general modes and the auxiliary switch handles the flashing modes. Instant strobe is available by pressing and holding the auxiliary switch for half a second from the off position. The UC52 can also be locked out to prevent accidental operation when stored.
