1. Color Temperature
For reading, ~4000K natural white. For relaxation, 3000K warm light. Adjustable is best for multi-purpose use.
2. Brightness & Dimming
Choose stepless dimming to adjust based on ambient light. Recommended desk illuminance: 300-500 lux.
3. Color Rendering
CRI Ra≥90 for accurate color reproduction. Below 80 causes eye fatigue over time.
4. Blue Light Protection
Choose RG0 (exempt) rated products to reduce retinal damage from blue light.
5. Flicker-Free
No visible flicker is a basic requirement. Point your phone camera at the light — no ripple means qualified.
