Product Overview
What This Product Is And Who It Is For
A 260 x 260 mm square board carrying 84 pieces of 2835, built for square downlights and ceiling fittings where a linear board wastes the aperture. Efficacy climbs from 185 lm/W at 2700K to 200 lm/W at 4000K and above, so the same part number can be quoted across a CCT range with the efficacy figure stated honestly per temperature rather than as a single headline number.
Key Benefits
Why Buyers Choose This Build
A square emitting area fills a square aperture, so less light is trapped inside the fitting
Efficacy quoted per colour temperature rather than as one best case figure
84 LEDs spread the load, which keeps the drive current per emitter low
One board covers 2700K through 5700K within the same mechanical design

Use Guide
Specifying And Installing It Correctly
- Quote the efficacy at the colour temperature actually being supplied, not the 4000K figure
- Use the 10W build where efficacy matters and the 13W build where output per fitting matters
- Allow the board to sit flat on the fitting back plate for heat transfer
