Efficient LED luminaire for suspended ceilings with visible support profile. Installed in large offices and corridors that require much illumination. This luminaire is rated as an IP44 luminaire when installed on suspended ceilings (IP20 in rear element), which increases its range of uses further. Choose amperage between 350mA and 1050mA depending on how much light you need and to create a uniform appearance. Losses are minimised and lumen output from the luminaire is maximised with LEDs mounted in the bottom. Refer to table in the user instructions for various lumen outputs. First class efficiency, 137lm/W at 350mA.
