18W Outdoor CCT LED Bulkhead - Grey

The Knightsbridge 18W LED bulkhead combines a die-cast aluminium body with an opal polycarbonate diffuser, rated IP65 for outdoor installation. The integrated LED gear tray offers three selectable colour temperatures — 3000K (1680lm), 4000K (1790lm), or 6000K (1810lm) — adjusted via a switch on the back plate before installation, allowing one fitting to serve different applications without stocking multiple SKUs.

Designed for external wall-mounting on commercial premises, residential pathways, car parks, building entrances and communal areas, the bulkhead provides 110-degree beam spread across a 360mm-diameter lens. The grey powder-coated aluminium housing resists impact and corrosion in coastal or industrial environments, while the anti-vandal construction withstands tampering in public or high-traffic locations. The fitting draws 18W on 230V mains and achieves 132.6lm/W efficacy.

The opal diffuser eliminates visible LED hotspots and spreads light evenly across doorways, loading bays and stairwells. The 92mm projection from the wall keeps the fitting low-profile while the die-cast rear plate provides a secure fixing point on masonry, render or timber cladding. The Class I earthed construction requires connection to mains earth. The LED module is rated for 50,000 hours to L70B50, which translates to approximately 11 years of continuous operation before output drops to 70% of initial lumens.

Product Specification Sheet

Product Manual

How is the colour temperature selected?

The CCT is adjusted via a switch on the LED gear tray before the bulkhead is sealed and mounted. Once installed, the colour temperature cannot be changed without removing the fitting from the wall and opening the rear plate. Most installations choose 4000K for neutral white output suitable for security and task lighting.

Is this suitable for coastal or industrial environments?

Yes. The IP65 rating protects against dust ingress and water jets from any direction, while the die-cast aluminium body and powder-coated grey finish resist corrosion in coastal salt spray and industrial chemical exposure. The anti-vandal construction also withstands impact in public areas.

Can it be mounted on a ceiling?

The bulkhead is designed primarily for wall-mounting but can be ceiling-mounted where the cable entry point on the rear plate can be accessed. The 110-degree beam spread works well for ceiling installation over doorways or loading bays.

What is the expected lifespan?

The LED module is rated for 50,000 hours to L70B50, meaning it will maintain at least 70% of its initial lumen output after 50,000 hours of continuous operation. This equates to approximately 11 years of 24/7 use or significantly longer in typical outdoor security lighting applications running dusk-to-dawn.
