Optimum Surface Mounted

Optimum Surface Mounted is the variant of the Optimum profile that fixes directly to the ceiling surface. With no suspension components no ceiling height is given up and no additional support structure is needed on concrete soffits. Where there is no suspended ceiling, or where a pendant would compromise circulation safety, it carries the solution of the range through.

The product is manufactured in twenty-four codes, crossing eight lengths with three output steps. Lengths are 675, 895, 1115, 1334, 1554, 1774, 1994 and 2214 mm. PL17U9C02C opens the range at 15 W and 1,445 lm in 675 mm; PL17U30C04C reaches the highest power in the series at 86 W and 7,720 lm in 2214 mm. Body width is 57 mm and height 85 mm; weight ranges from 1.9 kg to 4.7 kg. Power, flux and dimensions match the pendant model exactly, so both mounting types can be resolved on a single lighting calculation within a project.

The aluminium body is offered in white and black; the converter is a long-life, ENEC-compliant constant current type. LED modules from LUMILEDS, OSRAM and NICHIA are rated at 60,000 hours. Suitable for shopping malls, markets, offices, meeting rooms, living rooms, waiting lounges, stores, hospitals, schools, corridors, open-plan offices, airports and terminals, universities, libraries and public buildings. An LDT file for each type, the ISO 9001-2015, TS EN IEC 60598-2-1, EC and UKCA documents and the technical drawing are on the product page. Dimmable DALI driver and emergency kit are optional; UGR<19 glare control and CRI 90 colour rendering can also be supplied on request.
