Description
The Knightsbridge NH020B is an 80mm diameter recessed LED guide light with an integrated 1W blue LED behind a clear diffuser, set in a matt white die-cast aluminium bezel. The fitting projects just 3mm from the wall or step riser once installed, with a 50mm recessed depth behind the mounting surface. The integrated LED runs directly on 230V mains with no external driver required.
Designed for step risers, garden walls, decking stairs and perimeter pathways, the blue LED provides low-level directional light for nighttime navigation without overwhelming ambient darkness. The IP54 rating protects against dust ingress and water splashes from any direction, making the fitting suitable for outdoor hardscapes exposed to rain. The 75mm cut-out accepts a mounting sleeve for brick or masonry installation, and the 0.2m cable tail connects to mains wiring inside the wall cavity or back box.
The matt white bezel blends into rendered walls, painted masonry and white decking fascias during daylight, while the blue LED glow becomes visible after dark. The die-cast aluminium construction withstands outdoor temperature variation and UV exposure without degrading. At 1W per fitting, multiple guide lights can be run on a single lighting circuit without significant load, making them practical for illuminating entire staircases or garden paths with consistent spacing.

Frequently Asked
What depth of wall or step riser is needed for installation?
The fitting requires 50mm recessed depth behind the mounting surface, plus space for the 0.2m cable tail and electrical connection. A minimum 70mm cavity depth is recommended for safe installation in brick or block walls.
Does the blue LED use a coloured filter or is it a blue-emitting LED?
The blue light comes from a blue-emitting SMD LED chip behind a clear diffuser, not a white LED with a coloured filter. This gives a purer blue tone without filtering losses.
Can multiple fittings be wired on the same circuit?
Yes. At 1W per fitting, multiple NH020B guide lights can be wired in parallel on a single lighting circuit without exceeding typical circuit capacity. For a full staircase or long pathway, consult a qualified electrician to calculate the total load.
Is the fitting dimmable?
No. The integrated LED runs at fixed output on 230V mains and is not compatible with dimmer switches.
