LED Panel Light vs Troffer: Which Ceiling Light Is Right for Your Project?
LED panels and troffers are the two dominant commercial ceiling lighting form factors, together representing over 65% of office and institutional lighting specifications. The choice between them impacts not just aesthetics — it determines ceiling plenum depth requirements, glare compliance (UGR), light uniformity, and per-square-meter installation cost.
With 3,200+ panel lights and 1,800+ troffer SKUs from 89 verified factories on Compare2Best, this comparison focuses on the procurement-relevant differences that engineering specs and facility managers need to evaluate.
| Feature | LED Panel Light | LED Troffer | Winner |
|---|---|---|---|
| Thickness | 10-18mm (ultra-slim) | 40-80mm (requires plenum space) | Panel (shallow ceilings) |
| Light Guide | Edge-lit PMMA light guide plate | Direct-lit lens + parabolic reflector | -- |
| UGR (Glare Rating) | UGR <19 (prismatic diffuser) | UGR 16-22 (parabolic louver) | Troffer (glare control) |
| Efficiency (lm/W) | 100-130 lm/W | 90-120 lm/W | Panel (10-15% higher) |
| Uniformity | 0.75-0.85 (no dark spots) | 0.65-0.80 (slight edge shadows) | Panel (more uniform) |
| CRI Options | CRI 80/90/95 widely available | CRI 80/90 (95 limited) | Panel (wider CRI range) |
| Dimming | 0-10V / DALI / TRIAC | 0-10V / DALI (TRIAC limited) | Panel (broader compatibility) |
| FOB Price (600x600, CRI80) | $18-45 (1000pcs) | $15-38 (1000pcs) | Troffer (15-20% cheaper) |
| Lifespan (L70) | 50,000-72,000 hrs | 50,000-60,000 hrs | Panel (slightly longer) |
| Best Applications | Office, hospital, school, lobby | Office building, corridor, garage | Application-dependent |
| Ceiling Type | T-bar, plaster, surface, suspended | T-bar (standard 600x600/300x1200) | Panel (more flexible) |

Decision Guide
Decision Guide
Step 1: Check ceiling depth. Plenum <80mm -> panel light only. Plenum >80mm -> both viable.
Step 2: Check budget. Under $25/fixture -> troffer. $25-50/fixture -> either. Above $50 -> panel (CRI 90+ premium).
Step 3: Check glare requirements. EN 12464-1 requires UGR<19 for offices. Panels typically deliver UGR 16-19. Troffers with parabolic louvers can achieve UGR<16 for surgical prep areas and design studios.
Step 4: Maintenance model. Frequent relamping (24/7 server rooms) -> troffer (replace tubes individually). Long-term low-maintenance -> panel (5-8 year whole-fixture replacement cycle).
Bottom line: 70% of commercial office projects choose panels (aesthetics + efficiency), 30% choose troffers (cost + glare control). If you have the budget and care about visual comfort, panels are the right call.
