Low Glare Work Area Lighting

Sigma has been designed specifically to meet the needs of the modern office. Historically, office lighting was focused on limiting glare, but while category 2 lighting achieved this, it also made the area dark as the light was faced down. Sigma resolves this issue, delivering a low-glare solution, with evenly distributed lighting across the office space – not just downward lighting, but upward and sideways.

Low-glare and evenly distributed light give softer lighting working conditions and helps with eye fatigue, mental health, and better focus; overall, creating a more productive working environment.

  • LG7 fully compliant
  • Flicker-free performance helps decrease eye fatigue and improves focus
  • Balanced light distribution for enhanced visual comfort
  • Micro-prism diffuser technology keeps unmatched efficacy of up to 133Llm/W
  • Standard fixed-output or digital dimmable options available

High-Performance Lighting

The Sigma provides superior performance thanks to a central micro-prism optic with an efficacy of up to 133Llm/W and an opal side diffuser that distributes light evenly and eliminates glare.

Sigma provides solutions ranging from 2,000 to 4,200 lumens with a lifetime of 100K hours providing unfailing performance and ideal for any working space

  • 2,000 to 4,200 lumen options available
  • Unmatched efficacy of up to 133Llm/W
  • 4000K neutral-white CCT
  • High colour rendering of CRI> 80
  • Extra long LED lifespan 100,000 hours
  • 5 Year Warranty

Balanced Lighting for Optimal Working Conditions

Guaranteeing a low-glare lighting solution, Sigma has the ability to contribute to a reduction in eye fatigue, improved mental health, and better focus. A much better option than outdated category 2 lighting, Sigma delivers evenly distributed lighting across office space, reducing areas of darkness

  • Ultra-low glare lighting solution
  • Even ligh distribiution
  • Optimised lighting conditions
  • Flicker-free performance

Flexible Installation with Swing Tabs


The swing-tabs allow for an easier and more flexible installation, into a grid ceiling, plasterboard, or even more elaborate ceiling types. Installation of the fixture can be carried out from below, so there’s no need for deep ceiling voids. This makes Sigma ideal for use in shallow ceiling voids, adding to their adaptability.

TPa Fire Rating


It can be hard to find LED panels that are suitable for projects where fire-rating and safety standards are required. Sigma is a TPa panel, ensuring that it meets the requirements for Building Regulations in closed-in areas such as corridors. This allows a great deal of flexibility over where Sigma can be installed
