The IP65 polycarbonate housing suits both wall and ceiling mounting in internal or external installations where lighting automation, emergency illumination and weather resistance are all required.\u003c\/p\u003e\n\u003cp\u003eDesigned for commercial corridors, stairwells, loading bays, car parks, storage areas and external walkways where lights need to activate automatically and provide emergency backup during mains failure, the bulkhead combines three functions in one fitting: presence-triggered switching via the microwave sensor, colour temperature selection via a recessed switch on the gear tray, and emergency operation that maintains illumination at 190lm for three hours when the mains supply is interrupted. The sensor detection range, lux threshold and hold time are all adjustable via potentiometers accessed when the hinged gear tray is opened.\u003c\/p\u003e\n\u003cp\u003eThe 256mm circular polycarbonate body mounts flush to the wall or ceiling with 74mm projection and conceals a hinged LED gear tray, accessible without fully removing the fitting. The opal polycarbonate diffuser gives a wide 115° beam angle, distributing light evenly across circulation spaces. The CCT switch allows the colour temperature to be changed post-installation: 3000K warm white outputs 730lm, 4000K neutral white outputs 810lm, and 5700K cool white outputs 780lm. The SMD LED source has a rated L70B50 life of 50,000 hours and a CRI \u0026gt;80. Push-fit fast-fix terminal blocks simplify first-time wiring and maintenance access.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003e256 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e74 mm\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\u003eDiffuser\u003c\/td\u003e\n\u003ctd\u003eOpal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEmergency\u003c\/td\u003e\n\u003ctd\u003eMaintained \/ Non-maintained \/ Switched\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Technology\u003c\/td\u003e\n\u003ctd\u003eSMD LED\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Included\u003c\/td\u003e\n\u003ctd\u003eYes\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\u003eL70B50\u003c\/td\u003e\n\u003ctd\u003e50000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnergy Rating (Class) post 2021 SLR\u003c\/td\u003e\n\u003ctd\u003eD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBeam Angle\u003c\/td\u003e\n\u003ctd\u003e115\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCCT\u003c\/td\u003e\n\u003ctd\u003e3000\/4000\/5700 K\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\u003e730 \/ 810 \/ 780 lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumens (Light Source only)\u003c\/td\u003e\n\u003ctd\u003e900 lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumens (Em. mode)\u003c\/td\u003e\n\u003ctd\u003e190 lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e9\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEfficacy\u003c\/td\u003e\n\u003ctd\u003e118.41 lm\/W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCRI\u003c\/td\u003e\n\u003ctd\u003e\u0026gt;80\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDriver Type\u003c\/td\u003e\n\u003ctd\u003eConstant Current\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty Information\u003c\/td\u003e\n\u003ctd\u003e(excluding battery)\u003c\/td\u003e\n\u003c\/tr\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\/products_4134449_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does the emergency function do?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe integrated emergency module maintains illumination at 190lm for three hours when the mains supply fails. It operates in maintained mode (always lit when mains is present, then switches to battery during outage), non-maintained mode (only lit during outage), or switched mode (controlled by a light switch normally, then auto-lit during outage). The emergency battery recharges from the mains when supply is restored.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does the microwave sensor work?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe microwave sensor detects movement within its range and triggers the light to switch on. Detection range, lux threshold (the ambient light level below which the sensor will activate) and hold time (how long the light stays on after last detecting movement) are all adjustable via potentiometers on the gear tray. This allows the sensor to be tuned to the specific installation environment.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan the colour temperature be changed after installation?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. A recessed CCT switch on the hinged gear tray allows the colour temperature to be changed between 3000K warm white, 4000K neutral white, and 5700K cool white without re-wiring. Each setting produces a different lumen output: 730lm at 3000K, 810lm at 4000K, 780lm at 5700K.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs it suitable for external installation?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The IP65 rating provides protection against dust ingress and water jets from any direction, making the bulkhead suitable for external wall or soffit mounting in sheltered or exposed locations.
