The Osiris bulkhead from Ledison is a 20W LED fitting with a slim circular profile and a white finish, built for indoor and outdoor use thanks to its IP65-rated plastic case. It suits ceilings and walls where a neutral, minimalistic look is wanted, and works equally well in a hallway, stairwell or on a building exterior.

Sensor operation

The microwave sensor version dims to a low background level and brightens on detecting movement, useful in corridors or hallways where full brightness is not always needed.

Where to use it

Its slim, circular design and IP65 rating make it suited to stairwells, corridors, entrances and exterior walls where a discreet, low-profile fitting is preferred over a bulkier luminaire.
