LED flat panels in the three sizes a commercial ceiling uses — 2×2, 2×4 and 1×4 — from 40W to 50W and 4000 to 6250 lumens, in fixed 4000K and 5000K and in selectable-CCT versions. Ultra-thin profiles are carried alongside standard depths, and 347V models cover the higher-voltage supply common in Canadian commercial and institutional buildings.
Panel size, wattage, lumen output, colour temperature, voltage and dimming are published per SKU. Voltage is the specification that most often stops a job in this category — a 120-277V panel and a 347V panel look identical on a shelf and are not interchangeable.
Surface-mount frames are stocked with the panels. Not every ceiling has a grid to drop into, and carrying the frame alongside the fixture keeps a retrofit from becoming a two-supplier order.
