E-Pro Downlight LED Light | 1 x 10 | Recessed | 3000K/4000K | Customisable

For open plan offices and commercial fit-outs where glare control is a specification requirement, a cellular recessed linear downlight with round aperture optics is more effective than a standard recessed linear with an open diffuser. The individual cells each contain their own precision optic, which limits the visible brightness of the light source from oblique angles and reduces discomfort glare for occupants seated below. Linear Lights stocks the E-Pro, a UK-manufactured architectural recessed linear downlight with diamond-cut reflectors and CRI >90Ra, available in 3000K or 4000K in black or white trim with gun metal optics, in configurations from 3 to 10 cells to suit different ceiling spans and lumen requirements.

A cellular LED downlight houses multiple individual LED cells within a single linear fitting, each with its own precision reflector or optic rather than sharing a single diffuser across the whole length. This approach gives significantly better glare control than a standard linear downlight because the light source within each cell is recessed and shielded, reducing the angle from which it is directly visible. The E-Pro range uses round aperture optics for ultimate glare control, is available in 1x3, 1x5, and 1x10 cell configurations, and achieves 106 lm/W efficacy with CRI >90Ra. In high-end commercial interiors, the cellular format also contributes a considered, architectural quality to the ceiling plane that a plain diffuser fitting cannot replicate.

A diamond-cut reflector is a precision-machined internal surface that controls exactly how light exits each cell, directing it more accurately and reducing stray light compared to a standard stamped or painted reflector. The result is a tighter, more defined beam per cell, which in a 10-cell linear fitting means highly consistent illumination across the full length without hot spots or uneven distribution. For commercial offices and reception areas where the quality of light directly affects the perception of the space, the difference between a diamond-cut cellular fitting and a standard recessed linear is visible both in terms of ceiling aesthetics and the quality of light on surfaces below. The gun metal optics finish on the E-Pro also adds a premium detail that reads clearly against both black and white trim options.
