Description
The Knightsbridge BL12ALEDS is a 305mm circular LED bulkhead with an integrated PIR motion sensor, delivering 1300lm of cool white 4000K light from a non-dimmable 14W SMD LED array. The IP54-rated polycarbonate housing protects against dust ingress and water splashes, making it suitable for semi-exposed outdoor locations, covered porches, carports, and internal corridors where moisture and dust are present.
The PIR sensor automatically activates the light when motion is detected within its range, reducing energy consumption in areas where constant illumination is not needed. This makes the bulkhead well-suited to residential entryways, shared hallways in flats, rear garden access routes, garage entries, and commercial back-of-house corridors. The surface-mount design fixes directly to flat surfaces without requiring recessing, and the Class II double-insulated construction does not require an earth connection.
The white polycarbonate body and diffuser resist impact and UV degradation better than acrylic alternatives, and the sealed construction prevents insects entering the light chamber. At 84mm projection from the wall or ceiling, the bulkhead sits low-profile while the 110° beam angle provides wide coverage. The 30,000-hour L70B50 rating indicates the LED will maintain at least 70% of its initial 1620lm output after 30,000 hours of operation, equivalent to approximately 10 years at 8 hours per day.
The cool white 4000K colour temperature provides neutral task lighting that does not shift colour perception, and the CRI rating above 80 ensures reasonable colour rendering for identifying objects and people. The fitting connects to standard 230V 50Hz mains wiring and carries a 3-year manufacturer guarantee.

Product Specification Sheet
Frequently Asked
What does IP54 mean and where can this be used?
IP54 indicates protection against dust ingress and splashes of water from any direction. The bulkhead is suitable for covered outdoor areas such as porches, carports, and eaves, as well as internal areas exposed to moisture and dust like utility rooms, garages, and commercial corridors. It is not waterproof and should not be installed in fully exposed locations with direct rain or hose-down cleaning.
How does the PIR sensor work?
The integrated PIR (passive infrared) sensor detects movement within its range and automatically switches the light on. After a preset time with no further motion detected, the light switches off. Detection range and time-out period depend on the sensor settings — consult the product specification sheet for adjustment instructions.
Can this be mounted on a ceiling or wall?
Yes. The surface-mount design allows the bulkhead to be fixed to either a ceiling or wall. The 84mm projection remains the same regardless of orientation, and the 110° beam angle provides similar coverage in either position.
Is the LED replaceable?
No. The 14W SMD LED array is integrated into the bulkhead and is not user-replaceable. The L70B50 rating of 30,000 hours indicates the LED will maintain useful output for approximately 10 years at 8 hours per day before eventual replacement of the entire fitting is needed.
