Description

This twin diffuser is a 1800mm clip-on polycarbonate cover designed for dual-tube T8 battens rated at 2x70W. The prismatic polycarbonate panel diffuses light from the fluorescent tubes below, reducing glare and protecting the tubes from dust accumulation in workshops, storage areas and utility spaces.

The diffuser clips directly onto compatible Knightsbridge T8 batten housings without tools, covering the full 1800mm length of the fitting. The prismatic texture on the polycarbonate breaks up direct sightlines to the tubes, softening the light output and making the fitting more comfortable to work under for extended periods. The 120mm width matches standard twin-tube batten profiles.

Rated IP20, the diffuser suits dry interior environments where dust protection is needed but moisture ingress is not a concern. The polycarbonate construction is impact-resistant and lighter than glass equivalents, making replacement straightforward if the diffuser is damaged during maintenance or relamping. The 56mm projection from the batten body when fitted means the complete assembly sits approximately 60mm proud of the ceiling or wall surface.

Frequently Asked

Which battens is this diffuser compatible with?

The diffuser fits Knightsbridge twin-tube T8 battens rated for 2x70W lamps with an 1800mm body length and 120mm width. Check the batten housing has the clip channel running along both edges before ordering.

Does it reduce light output?

Yes. The prismatic polycarbonate diffuses and scatters light, which reduces direct glare but also lowers measured lux at working height by approximately 15-20% compared to bare tubes. This trade-off is acceptable in most utility and workshop applications where comfort matters more than maximum brightness.

Can it be used in damp environments?

No. The IP20 rating means the diffuser and batten combination are suitable only for dry interiors. For garages, sheds or covered outdoor areas with moisture exposure, an IP65-rated batten with a sealed diffuser is needed instead.
