The CCT adjustment lets you select 3000K (1680 lumens), 4000K (1790 lumens) or 6000K (1810 lumens) on installation by switching a setting on the LED gear tray inside the fitting.\u003c\/p\u003e\n\u003cp\u003eDesigned for external walls, covered car parks, industrial loading bays, stairwells and public building entrances where emergency lighting compliance and automatic dusk-to-dawn operation are both required. The daylight sensor switches the bulkhead on when ambient light drops below a threshold and off again at dawn, removing the need for manual switching or separate timer controls. The emergency function provides maintained, non-maintained or switched emergency modes selectable during installation, with 190-200 lumens output in emergency mode for up to 3 hours during mains failure.\u003c\/p\u003e\n\u003cp\u003eThe die-cast aluminium body and opal polycarbonate diffuser provide impact resistance rated IK08, with anti-vandal polycarbonate fixings securing the diffuser to the baseplate.
