The UL-1571 Listed Series PL lighting units are mounted on the upper flange of our circular sight glasses. Combined, they offer glare-free illumination of the interior of vessels, tanks, hoppers, silos, mixers and other normally enclosed containers in nonhazardous locations. The Series PL lighting units described on this page can also be mounted on existing sight glass installations having the same viewing diameter.
