10 pcs 3Watt LED, 3W High Power LED Chip Super Bright Intensity SMD COB Light Emitter Components Diode 3W Bulb Lamp Beads DIY Lighting (Warm White 3000K)

I ordered these from a search (not google, but DuckDuckGo) having only the LED driver info of 3-4volts and 3W. The specs looked good so I ordered and tested the LEDs when they arrived. They are bright, I measured the voltage and amperage and found they used 3.3v and 530mA from a constant current driver. The specs for these LEDs indicate 3-3.4v and rated at 730mA but neither the original driver nor the new Chanzon LED Driver 600mA drew the full 730mA but both drivers only pulled the 530mA at full bright. I might try the 5W units as they must be extremely bright. Head sink needed for these as they get too hot to touch while operating.

I am using for my DIY projectthanks

A couple LEDs stopped working in our electric fireplace, had to replace all eight with these high power bulbs.Worked perfectly
