One of the most popular questions we get, either in store or online, is about which light is the brightest light we have in stock. Using 18 CREE XM-L LED’s and powered by an incredulous 28 lithium-ion 18650 batteries, the FOURSEVENS XM18  produces 15,000 lumens. That’s not a type-o, the XM18 produces a whopping 15,000 lumens, which is three times brighter than our second brighest light: the Olight X6. Compared to other lights that produce this much light, the XM18 is actually self contained and rather portable given its size. The light comes standard with a heavy duty shock-proof case, and has three modes plus a strobe. This light is strictly custom order, and must be called in ahead of time if you wish to purchase one.
