The Lumenox LBX luminaires are intended for use in Zone 1/21 Hazardous areas as fixed bulkhead lights. The LBX range benefits from a compact and low profile marine grade LM6 aluminium housing. A precision machined  seal provides an IP66 rating for outdoor or indoor use and ensures the utmost in reliability and performance under even the harshest  of conditions. The LBX range utilises Elise™ technology to give market-leading glare performance and illumination quality.


The LBX emergency bulkhead shares the same design philosophy as the rest of the Lumenox range being high performance  and easy to install and maintain. Utilising Lumenox’s LDXE emergency module, they provide 3 hours of reliable illumination after  mains power fails. Competitors’ products often require that once the lid/cover is removed, a separate LED tray must be removed to gain access to wiring. The Elise™ technology used in the LBX is mounted to the lid, meaning that removal of only four  screws gains access to the internals for maintenance and installation. Gland entries on each side enable simple through-wiring.
