LED panels and louvre luminaires: guide for offices and commercial spaces

Good office lighting is bright, even and glare-free. This guide explains what matters with LED panels and louvre luminaires: mounting, glare (UGR), illuminance, colour temperature, efficiency and control. You will find all luminaires in the category Louvre luminaires & panels.

LED louvre luminaires and panels for offices, practices and schools

Our LED louvre luminaires and panels are made for display screen workstations, meeting rooms, practices and training rooms. They fit into lay-in grid ceilings and plasterboard ceilings or are mounted directly on the ceiling as surface-mounted luminaires. Every luminaire comes with data sheet, mounting instructions and LDT files for DIALux and Relux.

Recessed, surface-mounted or plasterboard – which mounting suits?

• Recessed in grid ceilings (lay-in ceilings): the luminaire replaces a ceiling tile. Most of our models are designed for this, for example OFFICE MINI 2.0, CLASSIC SLIM 2.1 or SOFTIELIGHT.
• Plasterboard ceilings: for closed ceilings there are versions with a recessed frame, e.g. CLASSIC SQUARE LED for plasterboard.
• Surface-mounted: where there is no suspended ceiling, mount the surface-mounted version, e.g. OFFICE LB LED surface-mounted or CLASSIC ECO LB LED surface-mounted.
• Long formats: for corridors and narrow rooms, the LONG models are suitable, e.g. OFFICE LONG LB LED.

Glare: what UGR<19 and UGR<17 mean

The UGR value (Unified Glare Rating) describes how much a lighting installation dazzles. The lower the value, the more pleasant for the eyes. For office work at a screen, the EN 12464-1 standard requires a maximum value of 19. Many of our panels achieve UGR<19. The OFFICE LB series even achieves UGR<17 and is therefore also suitable for demanding workstations. Important: the UGR value also depends on room size and layout. A lighting calculation provides clarity.

How much light does an office need?

Guide values according to EN 12464-1 (minimum illuminance, maximum UGR, minimum colour rendering Ra):

• Writing, reading, screen work: 500 lx, UGR 19, Ra 80
• Meeting and conference rooms: 500 lx, UGR 19, Ra 80
• Technical drawing: 750 lx, UGR 16, Ra 80
• Filing, copying: 300 lx, UGR 19, Ra 80

For binding planning, the original standard applies.

Colour temperature, efficiency and control

• Colour temperature: 4000 K (neutral white) is standard in offices, 3000 K feels warmer and suits receptions and meeting rooms. With Tunable White (2700–6500 K), for example SOFTIELIGHT Tunable White or CLASSIC Tunable White, you adapt the colour temperature to the course of the day.
• Efficiency: modern panels achieve over 150 lm/W, the CLASSIC SLIM 2.1 HE up to 179 lm/W. This reduces electricity costs and heat load.
• Control: depending on the model on/off, DALI for lighting control and presence detectors, or with an emergency lighting option for escape routes.
• Damp rooms: for kitchens, laboratories or changing rooms there are IP44 versions, e.g. CLASSIC LED IP44.

Frequently asked questions

What does UGR<19 mean for LED panels?

UGR stands for Unified Glare Rating and describes the glare of a lighting installation. For office and screen work, the EN 12464-1 standard requires a maximum value of 19. The lower the value, the more glare-free the light.

What size are louvre luminaires for lay-in ceilings?

The common grids are 600 × 600 mm and 625 × 625 mm. For long grids there are formats such as 1200 × 300 mm. Check the ceiling grid before ordering – you will find the exact installation dimensions in the data sheet.

How many lux does an office workstation need?

For writing, reading and screen work, EN 12464-1 specifies at least 500 lux. For technical drawing it is 750 lux, for filing and copying 300 lux.

Which colour temperature is best for the office?

4000 K (neutral white) is used most often because it supports concentrated work. 3000 K feels warmer and suits receptions and meeting rooms. Tunable White panels can be adjusted between 2700 and 6500 K.

Can I install an LED panel without a suspended ceiling?

Yes. Many models are available as surface-mounted luminaires that are screwed directly to the ceiling. For plasterboard ceilings there are versions with a recessed frame.

Do you supply LDT files for DIALux and Relux?

Yes. For every luminaire you will find the data sheet, mounting instructions and LDT files for download on the product page. We are also happy to prepare a lighting calculation for your project.
