The integrated SMD LED gear tray is CCT-adjustable across three colour temperatures (3000K at 1020lm, 4000K at 1080lm, 6000K at 1090lm), selected on installation via a switch on the driver. The IP65-rated black aluminium body and impact-resistant polycarbonate diffuser protect the electronics from dust, rain and hose-down conditions.\u003c\/p\u003e\n\u003cp\u003eDesigned for external building perimeters, loading bays, car parks, pathways and other safety-critical outdoor zones, the bulkhead provides three emergency modes: maintained (always on), non-maintained (activates only on mains failure), and switched (manually controlled with emergency override). The photocell sensor automatically switches the light on at dusk and off at dawn, reducing manual intervention and energy consumption. The eyelid cowl at the top of the fitting reduces upward light spill and directs output downward, minimising glare and light pollution.\u003c\/p\u003e\n\u003cp\u003eThe die-cast aluminium construction provides heat dissipation for the LED driver and resists corrosion in coastal or high-humidity environments. Anti-vandal fixings secure the diffuser to the body, making unauthorised removal more difficult in public or high-traffic areas. The 110-degree beam angle gives broad coverage without creating harsh shadows on paths or entrances. The fitting measures 360mm diameter by 94mm projection from the wall and weighs approximately 2.5kg installed.\u003c\/p\u003e\n\u003cp\u003eThe emergency battery provides 105-120lm output (depending on CCT selected) for up to three hours during mains failure, meeting UK emergency lighting standards for escape routes and final exits. The L70B50 rating of 50,000 hours indicates the LED will retain at least 70% of its initial output after approximately six years of continuous operation. The 5-year warranty covers the LED driver and housing but excludes the emergency battery, which is a consumable component.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\" style=\"width: 100%;
