Description
The Knightsbridge MRBLED is a 32W CAT2 recessed modular LED fitting designed to drop into standard 600mm x 600mm suspended ceiling grids. The fitting outputs 3370 lumens of cool white 4000K light through a clear diffuser panel backed by a CAT2 anti-glare louvre, which reduces screen glare and visual discomfort in office environments with desk-level monitors and computer screens.
Designed as a direct replacement for older 4 x 18W T8 fluorescent modular fittings, the MRBLED fits into the same grid aperture and reduces power consumption by approximately 40 per cent while delivering comparable light output. The fitting suits commercial interiors including offices, classrooms, healthcare reception areas and retail back-of-house zones where 600x600mm suspended ceilings are already in place. The IP20 rating limits use to dry indoor environments with no moisture exposure.
The white-painted steel housing measures 595mm x 595mm to fit within the grid cell, with a recessed depth of 52mm above the ceiling line once installed. The integrated LED module is rated for 50,000 hours to L70B50 (the point at which 50 per cent of LEDs reach 70 per cent of initial light output), which translates to approximately 17 years of operation at 8 hours per day. The fitting is non-dimmable and runs on constant-current driver circuitry, which minimises flicker and delivers stable output across UK mains voltage variation.
The CAT2 classification indicates the louvre geometry meets Category 2 anti-glare requirements under EN 12464-1, the European standard for workplace lighting. This makes the fitting suitable for environments where users face screens at typical desk heights of 720-750mm and viewing angles between 55 and 85 degrees from horizontal.

Frequently Asked
What ceiling grid size does this fit?
The fitting is designed for standard 600mm x 600mm suspended ceiling grids. The 595mm x 595mm outer dimension provides clearance to drop into the grid cell without binding, while the flange rests on the T-bar framework.
Can this replace existing fluorescent modular fittings?
Yes. The MRBLED is a direct replacement for 4 x 18W T8 fluorescent modular fittings in the same grid size. It delivers comparable light output at 3370lm while consuming 32W instead of 72W, reducing power consumption by approximately 40 per cent.
What does CAT2 mean for glare control?
CAT2 refers to Category 2 anti-glare classification under EN 12464-1, the European workplace lighting standard. The louvre geometry reduces screen glare for users working at desk heights of 720-750mm with monitors, making the fitting suitable for office environments with computer workstations.
How long will the LED module last?
The LED module is rated for 50,000 hours to L70B50, meaning 50 per cent of the LEDs will still deliver at least 70 per cent of initial light output after 50,000 hours of operation. At 8 hours per day, this equates to approximately 17 years of service life.
