China released GB 30255-2026, mandatory energy efficiency for indoor LEDs, effective Sep 2027.
Key Changes
Smart lights regulated for the first time. Coverage expands from ~40% to ~90% of fixtures.
Comparison Table
| Metric | Old (2019) | New (2026) |
|---|---|---|
| Coverage | Basic downlights only | 90%% of indoor LEDs + smart |
| 3rd tier efficiency | ~45 lm/W | 55 lm/W (+22%%) |
| Standby power limit | None | <=2.5W |
| Ra>=90 bonus | No | ~10 lm/W relaxation |
Why This Matters for Smart Lighting
The standby power cap is huge. The new 2.5W limit forces driver optimization. Our Tuya Zigbee drivers at nexLAMP run under 0.5W standby.
Buying Guide: 3 New Metrics
- Efficiency Grade: Replace wattage as primary filter (Grade 1 >=75 lm/W, Grade 2 >=65 lm/W)
- Standby Power: Smart lights must declare (<=0.5W excellent)
- Color Rendering Index: Ra>=90 for eye-care spaces with policy support
