How to Judge LED Light Quality

6 ways to quickly assess LED fixture quality.

1. Check Luminous Efficacy: Below 80 lm/W is low-end; above 120 lm/W is premium.

2. Check Color Rendering Index: Ra above 80 is acceptable; Ra above 90 is excellent.

3. Check for Flicker: Point your phone camera at the LED—no rolling lines is a good sign.

4. Check Heat Dissipation: Aluminum heat sinks are better than plastic; the fixture should not be too hot to touch after 30 minutes.

5. Check Build Quality: Seamless joints, and certification marks like 3C, CE, or UL.

6. Check Warranty: Quality LEDs come with a 3-5 year warranty.
