Description
The Knightsbridge 6ft LED emergency batten delivers 50W and 5350lm of 4000K cool white light from an integrated LED strip housed in a matt silver aluminium and polycarbonate body measuring 1768mm long, 60mm wide and 52mm deep. A built-in 3-hour emergency battery module maintains lighting during mains power failure, operating in maintained, non-maintained or switched emergency modes depending on installation wiring.
Designed for commercial, retail and industrial settings where emergency lighting compliance is required, the batten suits workshops, corridors, stairwells, warehouses and communal areas in multi-occupancy buildings. The fitting mounts via a rear terminal box that accepts mains wiring and switches the unit between normal and emergency operation without external control gear. The 102lm/W efficacy keeps running costs lower than fluorescent battens of equivalent output.
The opal polycarbonate diffuser softens the LED strip to reduce glare on polished floors and screens while maintaining 5350lm full-brightness output on mains power. In emergency mode the output drops to 205lm, sufficient for safe egress lighting under UK Building Regulations. The IP20 rating suits dry indoor environments, and the Class I earthed construction requires standard three-core wiring to a protective earth.
The matt silver finish on the aluminium body provides a neutral appearance that sits comfortably in both finished commercial interiors and rougher industrial spaces. Knightsbridge backs the LED module and driver with a 5-year warranty, excluding the rechargeable battery which has a separate service life.

Frequently Asked
What emergency modes does the batten support?
The fitting can be wired for maintained (always lit), non-maintained (lit only during power failure), or switched emergency operation. The mode is determined by the wiring configuration during installation, not by an external switch on the fitting itself.
How long does the emergency battery last?
The internal battery provides 3 hours of emergency lighting at 205lm output when mains power is lost. The battery recharges automatically when mains power returns. Battery lifespan depends on charge/discharge cycles and is excluded from the 5-year warranty on the LED and driver.
Is this suitable for damp areas like bathrooms or outdoor covered areas?
No. The IP20 rating means the fitting is designed for dry indoor locations only. For damp areas, bathrooms or covered outdoor zones an IP65-rated emergency batten would be required.
What ceiling height and spacing works best for this output?
At 5350lm and 4000K, this batten suits ceiling heights of 2.4-4m in commercial and industrial settings. For general workspace lighting, typical spacing is 3-5m between parallel rows depending on the desired lux level and ceiling reflectance.
