The 2x4 troffer above your desk is doing more work than it looks — colour accuracy, glare control, and dimmability all affect how a commercial space actually feels to work or shop in. This collection covers 1x4, 2x2, and 2x4 LED flat panels, back-lit panels, and troffers in standard and CRI 90+ premium options.
Standard panels (CRI 80) suit general office and back-of-house retail space; CRI 90+ options are worth the upgrade anywhere colour accuracy matters — dental and medical clinics, retail displays, and showrooms all benefit from the truer colour rendering. Frame/grid panels sit into a standard T-bar ceiling grid, while center-basket troffers are a more traditional recessed profile — both are direct 2x2 or 2x4 fluorescent troffer replacements. Sensor-ready models with PIR receptacles let you add occupancy sensing without rewiring later.
DLC listed and rated 120-347V, with selectable wattage and CCT (typically 3000K-5000K) on most models so one SKU covers multiple spec requirements. Built-in motion and daylight sensor options help meet Alberta energy code requirements for occupancy-based lighting controls in commercial space.
What's the difference between a panel and a troffer? "Panel" typically refers to a thin, edge-lit LED fixture; "troffer" refers to a recessed fixture with a center-basket or lensed design. Both fit standard T-bar ceiling grids and are largely interchangeable for most commercial applications — the choice often comes down to aesthetic preference and existing ceiling cutout.
Is CRI 90+ worth the extra cost? For most general office space, CRI 80 is adequate. For any space where colour accuracy affects the customer or patient experience — retail, clinics, galleries — CRI 90+ is a worthwhile upgrade; see also our Architectural & Designer Lighting collection for even higher-CRI track and accent options.
