The Holt bulkhead luminaire has been intelligently created to be tough and easy to install. The fitting base is manufactured using high-grade polycarbonate material for durability and is mounted on a hinged metal gear tray for quick installation. The diffuser is made from top-quality thermoplastic polymers that have been designed to maximise the light output ratio (LOR). The 4000K standard option provides consistent, bright illumination to keep high-risk areas well lit.

For external applications and facilities such as toilets, storerooms, warehouses and corridors, the Holt luminaire provides high light output to make sure employees and persons can move around safely. To further enhance the protection this luminaire already offers, tamper-proof stainless steel screws can be supplied to secure the diffuser.
