GB 30255-2026 Is Coming: 3 Metrics More Important Than Wattage

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

  1. Efficiency Grade: Replace wattage as primary filter (Grade 1 >=75 lm/W, Grade 2 >=65 lm/W)
  2. Standby Power: Smart lights must declare (<=0.5W excellent)
  3. Color Rendering Index: Ra>=90 for eye-care spaces with policy support

GB 30255-2026 filters out low quality products.
