This SMD5730/5630 round LED lamp board uses San'An chips at 110–120 lm/W and a CRI of over Ra85 for DIY bulb, downlight, spotlight, and floodlight modification. Ten wattage options from 3W to 36W across multiple diameter sizes. 300mA constant current. Three color temperatures — warm white, natural white, and cool white. Lifespan of 50,000 hours.
Requires an external LED driver — not for direct mains connection.
Certified to CE, CCC, and RoHS standards.
