The integrated LED delivers between 1,300-1,800 lumens depending on the wattage and CCT combination selected, with DALI and push-dim compatibility for smooth dimming control.\u003c\/p\u003e\n\u003cp\u003eDesigned for commercial corridors, stairwells, industrial zones, external building facades and residential utility areas, the bulkhead carries IP65 rating for dust and water ingress protection and IK10 impact resistance, making it suitable for locations where fixtures may be exposed to hose-down cleaning, coastal moisture or accidental knocks. The UV-stabilised polycarbonate body and diffuser resist yellowing under prolonged outdoor UV exposure, maintaining the white finish over time.\u003c\/p\u003e\n\u003cp\u003eThe 65mm projection from the mounting surface keeps the profile low for ceiling and wall mounting where headroom or clearance is limited. Installation uses push-fit terminals for fast wiring, and the diffuser locks on via a twist-lock mechanism that allows access to the gear tray without tools for lamp replacement or maintenance checks. The hinged gear tray swings clear once the diffuser is removed, exposing the driver and DIP switches. Optional bezel accessories (sold separately) in black, chrome and eyelid styles allow the appearance to be adjusted for different interior or exterior schemes.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003e300mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e65°\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003ePolycarbonate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eWhite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClass\u003c\/td\u003e\n\u003ctd\u003eII\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP Rating\u003c\/td\u003e\n\u003ctd\u003eIP65\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Voltage\u003c\/td\u003e\n\u003ctd\u003e230V 50Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e14\/16\/18W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBeam Angle\u003c\/td\u003e\n\u003ctd\u003e130\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBeam Angle\u003c\/td\u003e\n\u003ctd\u003e130°\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLight Colour\u003c\/td\u003e\n\u003ctd\u003eCCT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumens\u003c\/td\u003e\n\u003ctd\u003e1300\/1400\/1400,1500\/1600\/1500,1600\/1800\/1700lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/datasheet-BTEVDALI.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eHow is the wattage and colour temperature adjusted?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe BT EVO uses DIP switches on the driver, accessible by removing the twist-lock diffuser and opening the hinged gear tray.
