Moreover, HD20 comes with an adjustable lanyard, a magnetic tailcap and a sophisticated user interface for flexible and convenient one hand operation.
Samsung’s LH351D and Cree’s XP-L HD emitter in neutralwhite tint (5.000K) enable HD20 to provide both spotlight and floodlight in one single flashlight. Using 90CRI for floodlight result in great color rendition at close ranges.
