The new top model in the Walther Pro XL series (Xtra Large) is identical to the XL7000r only in appearance. Its seven lenses produce 50 percent more light, namely a full 4500 lumens as measured by the ANSI FL1 standard. The output can be reduced to 40 or 10 percent. If the switch is held down for more than half a second, the Tactical Defense Strobe goes into action, keeping even the most determined attacker at bay. Power is supplied by a lithium-ion battery pack consisting of two 26650 rechargeable batteries that can be charged by cable without being removed. The flashlight contains a Cree LED XP-L chip and is splashwater protected (IPX4). It comes with a carrying strap and a rugged plastic case.
