Description

The Knightsbridge BATSCWM4 is a 1225mm (4ft) LED batten with adjustable wattage output (18W or 32W), adjustable colour temperature (3000K, 4000K or 5700K) and integrated microwave presence detection. The fitting is constructed from pressed steel with an opal polycarbonate diffuser and a white finish, designed to replace conventional fluorescent battens in commercial, industrial and residential applications.

The wattage and CCT switches are accessed via a hinged gear tray on the rear of the fitting, allowing installers to set the output before final fixing. At 18W the batten delivers 2600lm at 4000K (2380lm at 3000K, 2570lm at 5700K). At 32W it delivers 4490lm at 4000K (3950lm at 3000K, 4310lm at 5700K). The microwave sensor detects occupancy through ceilings and partitions, with adjustable sensitivity and hold-time settings to suit different room types and usage patterns.

The fitting uses rear and end conduit fixing points spaced at standard 600mm centres, making it compatible with existing fluorescent batten mounts and BESA boxes. Push-fit loop-in loop-out terminals on the gear tray allow daisy-chaining of multiple battens without needing connector blocks. The opal diffuser gives even light distribution across the 1225mm length with a 145-degree beam angle. The LED module carries a 60,000-hour L70B50 rating and a five-year warranty.

Frequently Asked

How does the microwave sensor work?

The microwave sensor detects occupancy by emitting low-power microwave signals that detect movement through ceilings, partitions and glazing. Sensitivity and hold-time are adjustable via controls on the gear tray, allowing the installer to set how sensitive the sensor is and how long the light stays on after the last movement is detected. Typical hold-times range from 30 seconds to 15 minutes depending on the setting.

What does adjustable wattage mean?

A switch on the gear tray allows the batten to be set to either 18W or 32W output before installation. The 18W setting is for smaller spaces or where lower brightness is acceptable, while the 32W setting provides higher output for larger areas or where more light is needed. Once set, the wattage remains fixed during operation.

What colour temperature should I choose?

3000K produces a warm white light similar to halogen, suited to residential and hospitality spaces. 4000K is neutral white, common in offices, schools and commercial areas. 5700K is cool daylight, used in industrial and task-heavy environments. The CCT can be changed by accessing the switch on the gear tray.

Can multiple battens be linked together?

Yes. The push-fit loop-in loop-out terminals on the gear tray allow daisy-chaining of multiple battens from a single feed cable without needing separate junction boxes or connector blocks. The terminals accept cable sizes up to 2.5mm² and the hinged gear tray provides access without removing the fitting from the ceiling.
