Description

This single diffuser is designed as a replacement or upgrade component for Knightsbridge 70W T8 batten fittings, measuring 1795mm in length to suit 6ft fluorescent tube installations. The diffuser is constructed from white polycarbonate with a prismatic surface pattern that refracts and softens the direct light output from the fluorescent tube, reducing glare in task areas such as workshops, storage rooms, corridors and retail back-of-house spaces.

The diffuser clips or slides into position beneath the main batten housing, covering the exposed tube and directing light downward rather than allowing it to spread laterally. The prismatic pattern breaks the light into smaller angles, distributing it more evenly across work surfaces and reducing the harsh line of light typically visible with bare fluorescent tubes. This makes the fitting more comfortable to work under for extended periods in task-focused environments.

The polycarbonate material is impact-resistant and lightweight, rated for IP20 dry interior environments. The 74mm width and 48mm projection match standard T8 batten profiles from Knightsbridge, though compatibility with other manufacturers' fittings should be confirmed by measuring the existing batten's diffuser housing before ordering. The white finish integrates cleanly with white or off-white ceiling installations.

Frequently Asked

Is this compatible with other brands of T8 batten?

The diffuser is designed for Knightsbridge 70W T8 battens and fits standard 1795mm single-tube housings with a 74mm width. Compatibility with other manufacturers depends on their batten profile dimensions. Measure the existing diffuser housing before ordering if you are replacing a non-Knightsbridge fitting.

Does the diffuser reduce light output?

Yes, to a small degree. The prismatic pattern refracts and diffuses the light, which softens glare but also absorbs a small percentage of the total lumen output. The trade-off is more comfortable working light with reduced direct glare from the tube.

Can it be used outdoors or in damp areas?

No. The diffuser carries an IP20 rating, which means it is suitable only for dry interior areas. For bathrooms, outdoor canopies or other damp or wet locations, an IP65-rated batten with sealed diffuser is required.
