5W LED Outdoor Security Bulkhead - White IP54

The Knightsbridge 5W LED outdoor security bulkhead is a polycarbonate-bodied wall light with an IP54 rating, an integrated 5W LED delivering 460 lumens at 4000K cool white, and dual-voltage capability to run on either 110V or 230V mains supply. The white polycarbonate base houses the LED driver and lamp, covered by an opal polycarbonate diffuser that distributes light across a 120-degree beam angle.

Designed for continuous low-level security lighting, perimeter walkways, loading bays, external stairwells, car parks, outbuildings, and site huts, the bulkhead is rated for both indoor and outdoor use. The IP54 rating provides protection against dust ingress and water splashes from any direction, making it suitable for locations exposed to rain but not direct water jets. The dual-voltage design allows the same fitting to be used on both standard domestic 230V circuits and 110V site supplies without modification.

The polycarbonate construction is impact-resistant and UV-stable, maintaining the white finish without yellowing under prolonged outdoor exposure. The fitting measures 197mm long by 108mm wide with a 78mm projection from the wall, fitting comfortably on standard brickwork or blockwork without needing recessed mounting. The opal diffuser conceals the LED module and softens the light output to reduce glare in pedestrian areas. The 5W consumption and 60,000-hour L70B50 rating (the point at which 50% of a batch will have declined to 70% of original output) give a service life of approximately 20 years at 8 hours per night before requiring replacement.

The Class II double-insulated construction eliminates the need for an earth connection, simplifying installation on older buildings where earth availability may be inconsistent. The fitting carries a 3-year warranty covering manufacturing defects and LED driver failure.

Product Specification Sheet

Product Manual

Can this be used on both 110V site supplies and standard 230V mains?

Yes. The bulkhead is designed to run on either 110V or 230V without modification or switching. Connect to the available supply voltage and the internal driver adapts automatically.

Is it suitable for outdoor use in exposed locations?

The IP54 rating provides protection against dust and water splashes, making it suitable for most outdoor wall-mounting applications including rain exposure. It is not rated for direct water jets or full submersion. Avoid mounting where the fitting will be directly hosed down or face high-pressure cleaning.

What does the 4000K colour temperature look like?

4000K is a cool white light, neutral in tone with a slight blue cast compared to warm white (2700K-3000K). It is commonly used in commercial, industrial and outdoor security applications where visibility and clarity are prioritised over warmth.

Does the bulkhead need an earth connection?

No. The Class II double-insulated construction eliminates the need for an earth wire, requiring only live and neutral connections. This simplifies installation on older buildings or locations where earth availability may be limited.
