Office 1245 33W/840 AL MA
The Office downlight range, which can be surface-mounted on the ceiling, offers a variety of general lighting solutions with numerous customisation options. Its optics features include an aluminium low-luminance louvre and an integrated opal shield, which eliminate glare from the LEDs and achieve an excellent Unified Glare Rating l/value (UGR <19). Typical applications include schools, offices and other spaces where computers are used.
