Twin 6ft 60W LED Emergency Batten 4000K - White

The Knightsbridge T8BLED26EM1 is a twin-tube 1790mm LED emergency batten delivering 60W and 6500lm output at 4000K cool white. Built around a pressed steel body with an opal polycarbonate diffuser, the fitting houses integrated LED modules and an emergency battery pack that operates in maintained, non-maintained or switched emergency modes depending on wiring configuration.

Designed for commercial, retail and domestic spaces requiring emergency lighting compliance, the batten mounts directly to ceiling surfaces or suspended from M8 threaded rods via the integral mounting bracket. The IP20 rating suits dry indoor environments including corridors, stairwells, offices, workshops, retail stockrooms and multi-storey car parks. The fitting acts as a direct replacement for traditional twin T8 fluorescent battens, using the same mounting centres and simplifying retrofits where ceiling access is limited.

The emergency function provides 280lm output for a minimum of three hours when mains power is lost, using an internal battery pack that recharges continuously during normal operation. The batten can be wired for maintained mode (always lit), non-maintained mode (only lit on mains failure), or switched mode where normal operation follows a wall switch but emergency operation overrides switching during power cuts. The 4000K colour temperature produces neutral white light that renders colours accurately for task work, stock-checking and general visibility without the warm yellow cast of 3000K or the clinical blue tone of daylight 6500K.

The pressed steel body measures 1790mm × 95mm × 85mm and weighs approximately 2.8kg including the emergency battery. The opal diffuser provides even light distribution across the full length without visible LED hotspots, and the 120-degree beam angle gives wide coverage suitable for ceilings between 2.4m and 4m high. The fitting carries a 5-year warranty on the LED and driver components, with the battery pack excluded and requiring periodic replacement as per BS 5266 emergency lighting standards.

Product Specification Sheet

What is the difference between maintained, non-maintained and switched emergency modes?

Maintained mode keeps the batten lit continuously, switching to battery power during mains failures. Non-maintained mode only illuminates on power loss, remaining off during normal operation. Switched mode allows normal on/off control via a wall switch but overrides switching during power cuts, providing emergency light regardless of switch position. Wiring configuration determines the mode.

How long does the emergency battery last?

The internal battery provides 280lm output for a minimum of three hours during mains power failure. The battery recharges continuously during normal operation and requires periodic replacement in accordance with BS 5266 emergency lighting standards, typically every 3-4 years depending on usage patterns and test frequency.

Can this replace a traditional twin T8 fluorescent batten?

Yes. The fitting uses the same 1790mm length and mounting centres as a traditional twin 6ft T8 fluorescent batten, making it suitable for direct replacement where ceiling access allows re-wiring to the mains and emergency terminals.

What ceiling height does this suit?

The 120-degree beam angle and 6500lm output suit ceiling heights between 2.4m and 4m. Below 2.4m the light may be uncomfortably bright for prolonged occupancy; above 4m the lux levels at floor level drop below typical office and retail standards.
