The SLEX-100 and REX-100 explosion-proof lights from Papailias features die-cast anodized aluminum parts. UL-844- and C-UL/CSA C22.2 No. 137-listed, the electric lighting fixtures are designed for hazardous locations. Both models use high-intensity halogen lamps to provide bright, glare-free illumination of the interior of vessels, tanks, hoppers, silos, mixers and other normally closed containers. The illumination port, used in conjunction with a standard sightglass, offers users many options, including the use of a video or TV camera.
