Description

The USL is an ultra slim, backlit luminaire that can be surface mounted or suspended. It is only 50mm thick and is available in a choice of lengths.When the fitting is suspended there is the option to have an additional uplight feature to illuminate the ceiling. The uplight feature comes with a range of diffusers giving a choice of beam angles; from 30° to 90° The USL is suitable for corridors, offices and educational applications.

This luminaire incorporates the latest diffuser optics utilising a choice of either a Polar frost acrylic diffuser or a micro-prismatic diffuser with an LED specific film for added efficiency. Incorporating these materials in conjunction with the LED boards provides a highly efficient DLOR, with excellent glare control.

The USL range is supplied with Osram (‘PrevaLED’) LED boards and can be ordered with either fixed output or DALI dimmable control gear.

The USL is available as an emergency fitting supplied integrally through the LED boards.
