RAB T17FA Field-Adjustable LED Troffer — 2×2 / 1×4 / 2×4 — 3500K/4000K/5000K — White
The RAB T17FA series are field-adjustable LED troffers available in three sizes — 2×2, 1×4, and 2×4 — with field-selectable wattage and field-selectable color temperature (3500K, 4000K, or 5000K). The 2×2 and 1×4 models offer 40/30/20W selectable; the 2×4 offers 50/40/30W selectable. All models support 0–10V dimming (10–100%), operate on 120–277V, are rated for damp locations, and are DLC Listed. Each size is available with factory-installed battery backup (/E) providing 90 minutes of emergency illumination at 120V or 277V. Backed by a 5-year limited warranty. Ships at maximum wattage and 4000K default.
