The Bell Series Swimming Pool Bulkhead is a circular LED luminaire engineered specifically for the demanding conditions of indoor pool environments. Featuring chlorine-resistant die-cast aluminium housings and a durable powder-coat finish, it delivers reliable long-term performance in high-humidity, corrosive settings. Available in white, grey, or black finishes as standard, the fitting integrates seamlessly into both traditional and contemporary pool designs. Four-way perimeter conduit entry with rear cable access simplifies installation and minimises disruption to existing tiled surfaces.

Further options include 3-hour emergency functionality with remote-test, DALI self-test, or wireless monitoring, alongside occupancy sensing for enhanced safety and energy efficiency. An optional eyelid accessory is also available to reduce upward light spill and improve visual comfort around the pool.
