The tray outputs 1725 lumens at 17.5W with a 120° beam angle, providing 105-135 lumens per watt depending on the selected colour temperature. A small switch on the tray lets the installer select 3000K warm white, 4000K cool white or 6500K daylight before final installation.\u003c\/p\u003e\n\u003cp\u003eDesigned for commercial, industrial and high-traffic residential applications needing ceiling-mount emergency lighting with motion control, the tray fits inside compatible bulkhead housings or can be mounted directly to a ceiling surface where a low-profile fitting is required. The integrated microwave sensor detects movement through non-metallic ceiling materials, switching the LEDs to full output when motion is detected and dimming or switching off after a preset timeout. Emergency mode provides maintained illumination during mains power failure, meeting UK emergency lighting regulations for corridors, stairwells, exit routes and communal areas.\u003c\/p\u003e\n\u003cp\u003eThe aluminium PCB base acts as a heat sink, keeping LED junction temperatures within operating limits across an ambient range of -10°C to +40°C. The isolated driver eliminates visible flicker and provides mains isolation between the 220-240V AC input and the low-voltage LED array. Installation uses a quick-fit push terminal (3-way or 4-way depending on emergency wiring configuration), eliminating screw terminals and reducing fitting time. The IP20 rating limits use to Zone 3 bathroom areas and dry indoor locations. CRI \u0026gt;80 ensures colour rendering suitable for general commercial and workspace applications.\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\u003e0.37\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e17.5W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumen\u003c\/td\u003e\n\u003ctd\u003e1,725\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnergy Rating\u003c\/td\u003e\n\u003ctd\u003eE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKelvin\u003c\/td\u003e\n\u003ctd\u003eVariable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColour Temperature\u003c\/td\u003e\n\u003ctd\u003eVariable\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 does the CCT adjustment work?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA small switch on the tray allows the installer to select one of three colour temperatures before installation: 3000K warm white, 4000K cool white, or 6500K daylight.
