Serious amounts of light demands a serious flashlight, and the RI-1100(TM) is just that: it packs 1100 raw lumens on High and over 1,000 feet (318 meters) of projection while still being a highly portable 8.6 inches long. The type III military grade hard anodized aluminum housing and sealed construction have been tested against shock, vibration, sun, salt, and moisture, ensuring years of trouble-free operation. Like the rest of the RI-Series line, the RI-1100 has a thermally protected circuit board, polycarbonate lens, and a tactical bezel. Backed by a Limited Lifetime Warranty.
