What You Can See at the Showrooms

Photos cannot show glare, beam spread or the real colour of light. At the showrooms you can stand under each fitting and compare them side by side before you decide.

  • COB downlights and spot lights for false ceilings, in warm, natural, cool white and 3-in-1. Shortlist from the COB downlight collection before you visit.
  • Aluminium and silicone LED profiles for cove, shelf and skirting lighting.
  • LED panel lights for offices, kitchens and study rooms.
  • Underwater lights for pools and fountains, and the Nerva artificial skylight with smart gateways.

Planning a Visit

Bring your ceiling height, room sizes and a few photos of the space. If you already have a shortlist, save the product links on your phone so the team can show you those fittings first.
