Lighting and Control

Light that changes without a site visit, dims itself at night, and tells us when a fitting fails before you notice.

How big does your sign have to be?

Tell us how far away it has to be read from. The letters below are drawn to the height they would actually need — the doorway and the person are there for scale.

These are estimates from the standard rules of thumb, not a quote. A real quote states the cap height, the illumination type, the return depth, the load in watts, the duty class and the warranty in months, for your building.

Duty class is the first question a retrofit quote turns on, because it decides the fittings. A retrofit is also specified by measured lux at the work surface, the existing load in watts, and the load after — a retrofit quoted only as a percentage cheaper is a retrofit nobody has measured. We quote measured watts saved per month, not a saving.

What this covers

Fabricated signage

Your name, built and lit — face-lit channel letters for a shopfront, halo-lit lettering for a reception wall, light boxes where frontage matters more than depth.

  • Cap height ≈ 25 mm per 3 m of reading distance
  • Return depth 60–100 mm
  • Halo standoff 25–50 mm

LED display

A screen specified by what it has to do: the distance it is read from, the light it competes with, and the hours it runs. The LED count is an output of that, never a selling point.

  • Shopfront P3–P5 · 1,500–3,000 nits
  • Street-facing P6–P10 · 3,500–5,000 nits
  • Minimum comfortable viewing distance ≈ pitch in mm

Lighting and control

Zones on their own schedules, dimmed after midnight, and an installation that reports its own health instead of waiting to be noticed.

  • Duty classes: trading hours, dusk to dawn, continuous 8,760 h/yr
