Description

The Knightsbridge SUR5 is a 40W LED slim line luminaire with an integrated LED delivering 3010 lumens at cool white (4000K) through a 1500mm matt black pressed steel housing. The fitting mounts either directly to the ceiling surface or via suspension cables (sold separately), allowing it to replace traditional T8 fluorescent batten fittings in commercial, retail and institutional spaces.

Designed for offices, corridors, retail stockrooms and workshop areas requiring functional overhead lighting, the SUR5 provides a 115° beam angle that distributes light evenly across wide floor areas without the banding common to narrower-beam fixtures. The 1500mm length suits rooms between 3-6m wide when used in continuous runs or paired at 2-3m intervals. Surface mounting fixes directly to plasterboard or concrete ceilings using the fixing points along the rear channel. Suspended installation uses optional suspension cables threaded through the integral mounting points to lower the fitting 300-600mm below the ceiling plane.

The pressed steel body and polycarbonate diffuser give the fitting an IP20 rating suitable for dry indoor environments, while the matt black finish reduces reflections under high ambient daylight and pairs cleanly with black acoustic ceilings and industrial-style interiors. The integrated LED is non-dimmable and rated for 25,000 hours of operation before requiring replacement. The fitting is Class I, requiring an earth connection during installation, and complies with ErP eco-design standards for commercial LED luminaires.

Frequently Asked

Is this dimmable?

No. The integrated LED is non-dimmable and operates at a fixed 40W output on 230V mains supply.

Can it be suspended below the ceiling?

Yes. The fitting includes mounting points for suspension cables, allowing it to hang 300-600mm below the ceiling plane. Suspension cables are sold separately and must be specified when ordering if suspended installation is required.

What colour temperature is the LED?

The integrated LED delivers cool white light at approximately 4000K, typical for commercial and workspace applications where task visibility is prioritised over ambient warmth.

What spacing is recommended between fittings?

For general office or corridor lighting, space multiple units 2-3m apart along the ceiling run. The 115° beam angle provides good overlap between adjacent fittings when installed at these intervals, reducing dark patches between units.
