The dominant feature of the design of these sign lamps is a double pane of clear float glass with polished edges. Ultra high bright LEDs emit light into the glass pane which is then reflected and dispersed on to the sand-blasted matt surface of the symbol carried by the sign. The symbol stands out brilliantly illuminated against a restrained dark background. The sign lamps are available in various versions for ceiling and wall mounting with various structural designs and operating modes.
