The Infinitum is machined from Titanium, one of the hardest and most corrosion-resistant metals known to man, and features a state of the art infinitely variable circuit with a memory feature so that the Infinitum can output from 7 to 200 lumens and can be programmed to activate at a preferred output level. The icing on the cake is the ultra-select Cree XRE- R2 WD bin LED; the R2's are the highest output, most efficient LED of this type available and the WD is the color bin - in this case an ultra-pure white.The Infinitum took a lot of hard work to create. Because Titanium is such a hard metal Olight gave up polishing them halfway through production and switched to a bead-blasted finish for the remainder. Because of our special relationship as their first retailer and distributor in the world we were able to secure for you, our customers, the first 100 units made with the more desirable polished finish. Serial numbers 1-101 are known as the American Edition.Regardless of whether you choose to use it as the ultimate Every Day Carry (EDC) or put it on the shelf as a treasured collectible the Olight Titanium Infinitum is sure to please the discrimiting buyer.Features:
