Description

This 4000K LED plate is a replacement component for the Knightsbridge 14W CCT LED Bulkhead with Corridor Function. The 224mm diameter disc carries an array of SMD LEDs that deliver 1160lm of cool white light at 4000K, or 140lm in emergency corridor mode. The plate retains full compatibility with the bulkhead’s integrated corridor function, which reduces output when no motion is detected to save energy while maintaining wayfinding illumination.

Designed for retrofitting existing bulkhead fittings where a fixed 4000K output is preferred over the variable CCT versions, the plate installs by removing the original LED disc and connecting the replacement to the same terminal block inside the bulkhead housing. The constant current driver remains in the base unit, so only the LED plate itself is changed. This allows facilities managers to standardise colour temperature across multiple bulkheads without replacing entire fittings.
