China's New LED Lighting Standard GB 30255-2026: What Buyers Need to Know

Starting March 1, 2026, GB 30255-2026 — China's mandatory energy efficiency standard for indoor LED lighting products — is now fully enforced. If you're manufacturing, specifying, or purchasing LED fixtures for the Chinese market, here's a practical breakdown of what changed and how it impacts your decisions.

What's New vs. the 2019 Standard?

The updated regulation brings three major changes:

1. Broader product coverage — The old version only regulated directional downlights. The new standard now covers non-directional LED bulbs, T8/T5 tubes, high-bay luminaires, and retrofit double-ended LED lamps.

2. Higher efficiency floors — Tier 3 (the minimum market-entry threshold) has been raised by 15-30 percent across most product categories.

3. Tighter parameter transparency — Luminous efficacy, color rendering index (CRI/Ra), and chromaticity tolerance are now mandatory disclosure items.

The Three Efficiency Tiers

The standard defines three tiers: Tier 1 (best-in-class), Tier 2 (mid-range), and Tier 3 (mandatory minimum). Products below Tier 3 cannot be manufactured or sold in China.

Tier	Downlight Efficacy	LED Bulb Efficacy	LED Tube Efficacy
1	120+ lm/W	110+ lm/W	120+ lm/W
2	100+ lm/W	95+ lm/W	105+ lm/W
3	85+ lm/W	80+ lm/W	90+ lm/W

Four Parameters That Matter

1. Energy Efficiency Tier — Don't just look at wattage. A 9W Tier 1 downlight at 120 lm/W produces roughly 1080 lm, while a Tier 3 unit at 85 lm/W only delivers ~765 lm — nearly 30% less light for the same rated power.

2. Luminous Efficacy (lm/W) — The single most important metric for comparing LED products. Higher efficacy typically indicates a better driver power supply with higher conversion efficiency, better thermal management, and slower lumen depreciation.

3. Color Rendering Index (Ra) — For general interior lighting, Ra80+ is the baseline. Tier 1 products often achieve Ra90+, which is recommended for living rooms, offices, and retail spaces where accurate color rendering matters.

4. Correlated Color Temperature (CCT) — Match your CCT to the application:

• 2700-3000K (Warm White): Bedrooms, restaurants, ambient lighting
• 4000K (Neutral): Living rooms, kitchens, offices
• 5000-6500K (Cool White): Work areas, task lighting, garages

Why This Matters for LED Driver Selection

Behind every high-efficacy fixture is a reliable constant-current LED driver. The driver conversion efficiency directly determines whether a fixture can meet Tier 1 requirements. At Nexlamp, our driver solutions deliver up to 93% conversion efficiency and maintain stable output at 85 degrees C ambient — a key factor in achieving and sustaining top-tier efficacy ratings.

Key Takeaway

Good LED = Right wattage x High efficiency tier (1/2) x Ra90+ + Scene-matched CCT + Reliable driver power supply

When sourcing LED products for the Chinese market post-March 2026, always verify the GB 30255-2026 compliance label and efficiency tier. The era of vague energy-saving claims is over — the new standard provides concrete, verifiable benchmarks.
