Knightsbridge LWB90 90W LED Low Bay Light 12,800lm 5500K

Knightsbridge LWB90 90W LED Low Bay Light

The Knightsbridge LWB90 LED low bay is a high-output commercial and industrial luminaire designed for warehouses, workshops, production areas and other large indoor spaces. Its low-profile housing produces powerful, efficient illumination while occupying less vertical space than a traditional round high-bay fitting.

The integrated 90W LED delivers 12,800 lumens of 5500K daylight white light. An 85° beam concentrates the output across the working area, while the opal diffuser helps distribute the light and reduce direct glare from the LED source.

A 0–10V dimmable driver is included, allowing the output to be adjusted when connected to a compatible 0–10V lighting control system.

High-Output Commercial Lighting

With a delivered efficiency of approximately 140 lumens per watt, the LWB90 provides substantial illumination while limiting power consumption to 90W. It is suitable for replacing older low-bay luminaires using fluorescent, metal-halide or other discharge lamps, subject to a suitable lighting design.

The 5500K daylight white colour temperature provides crisp, functional illumination for environments where visibility and task performance are important.

0–10V Dimmable Driver Included

The supplied driver supports 0–10V dimming. When connected to compatible controls, the light level can be reduced to suit occupancy, daylight availability or different working requirements.

A suitable 0–10V dimmer, controller or compatible sensor is required and is not included with the standard fitting.

Suspension Equipment Included

The low bay is supplied with:

• Two suspension hooks
• Two one-metre suspension chains

This allows the luminaire to be suspended from a suitable supporting structure. Optional surface-mount brackets are available separately for installations where direct mounting is preferred.

Optional Sensor and Emergency Accessories

The LWB90 can be expanded using compatible accessories available separately:

• LWBPIR: 360° PIR movement sensor
• LWBMIC: 360° microwave dimming sensor
• LWBEMKIT: low-bay emergency conversion kit

The optional controls can help reduce energy consumption in intermittently occupied areas, while the emergency kit adds backup illumination for an appropriately designed emergency-lighting scheme.
