The Brevis R (Recessed Light Source) and Brevis D (Diffuser) are large area downlights which can be surface (Standard) or suspended mounted.
The heatsinks is built into the body of the product which enables the downlight to run at cool temperatures without the common need for vents in the vertical walls. The Brevis therefore has a minimalist architectural appearance without any visible fixings and very light weight thanks to its aluminium construction.
The downlights also have an IP44 rating when surface mounted.
