Designed for professional use, Fenix HP35R is built to perform, with long runtimes. It is an ultra powerful headlamp with a long-distance 3000-lumen, 440-metre main beam, and impressive 1200-lumen floodlight, which can be used combined to produce a 4000-lumen, 450-metre distance. The lamp is powered by a 10,000mAh, rear mounted rechargeable battery pack, and controlled by a rotary mode switch with central brightness adjusting push button. The warm white main beam features 4 brightness levels of 50, 350, 800 and 3000 lumens. 2x 600 lumen neutral-white flood lights deliver 5, 50, 400 and 1200 lumens. Switch them all on to turn night into day with 4000 lumens of light! With large battery capacity, efficient, aluminium heat sink head and industrial quality components, HP35R can maintain extreme output much longer than a conventional headlamp, whilst effectively dissipating the heat generated and leading to longer service life. The heavy duty battery pack is easily removable from the headband and can be used in a bag or pocket in conjunction with the included extension cable. The battery case incorporates a 4x LED meter displaying charging and battery level status, plus a USB-C in/out socket for use as a 10,000mAh power bank. A red rear light with its own operating switch is incorporated for safety critical applications. This model is compatible with HP30R V2.0 battery boxes so that those seeking an upgrade can use their existing batteries. Fenix HP35R features an intelligent brightness downshift function which reduces output to minimum when in close proximity to an object (60mm), for added safety and to protect the lamp unit. This feature can be switched off if required.
