The white steel housing holds an opal polycarbonate diffuser that spreads light across a 120-degree beam angle, producing 130 lumens per watt under normal operation.\u003c\/p\u003e\n\u003cp\u003eDesigned for commercial corridors, office circulation areas, stairwells and communal spaces requiring maintained emergency lighting, the batten mounts to ceilings or walls via a screwless hinged bracket that allows the diffuser to swing open for lamp maintenance or inspection without removing fixing screws. Quick-fit push terminals on the rear accept mains and emergency circuit wiring without terminal screwdrivers, reducing installation time on multi-unit projects.\u003c\/p\u003e\n\u003cp\u003eThe IP20 rating suits dry indoor environments, while the IK06 impact resistance protects the diffuser from accidental knocks in public circulation areas. The 1220mm length and 85mm width keep the batten compact enough to fit between standard joist centres in suspended ceilings or against concrete soffits. At 1.45kg the unit can be supported by typical ceiling grid systems without additional bracing.\u003c\/p\u003e\n\u003cp\u003eThe integrated LED runs flicker-free across the full mains voltage range, maintaining consistent output without the visible strobing effect that can occur with lower-quality drivers. In emergency mode the battery-backed circuit activates automatically on mains loss, keeping the light output at a reduced level sufficient for safe egress until mains power returns or the 3-hour reserve is exhausted.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight (KG)\u003c\/td\u003e\n\u003ctd\u003e1.45\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e20W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumen\u003c\/td\u003e\n\u003ctd\u003e2,400\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnergy Rating\u003c\/td\u003e\n\u003ctd\u003eD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKelvin\u003c\/td\u003e\n\u003ctd\u003e4,000K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColour Temperature\u003c\/td\u003e\n\u003ctd\u003eCool White\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimmable\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBeam Angle\u003c\/td\u003e\n\u003ctd\u003e120\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLED or Halogen\u003c\/td\u003e\n\u003ctd\u003eLED\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eZone\u003c\/td\u003e\n\u003ctd\u003eSuitable for use in Zone 3 only\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eHow long does the emergency mode last?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe battery-backed emergency circuit provides 1.5-2W output for up to 3 hours after mains failure.
