3W Beads. Yikes! Tested with UPRTek CV600. Tested multiple of each kind.Natural White 4000-4500k – Horrible CRI at about 63, but it was at color temp stated. Definitely wouldn’t want to use this for anything unless you need yellow and green with a spike in blue.Blue 460-470nm – Peak at 458nm. Not in range.Royal Blue 440-450nm – Peak at 451nm. Package states 440nm. Not in range.Deep Red 650-660nm – Peak at 660. Package states 660nm.Full Spectrum 380-840nm – Peaks at 444nm blue. Not…
Works as expected, and much cheaper per unit to buy these along with Chanzon’s heatsinks and assemble yourself. Have purchased multiple sets of these chips after great success with the first batch. So far, every chip has worked perfectly. Mounted to the corresponding heatsinks also from Chanzon with a tiny dab of thermal compound (I used Céramique by Arctic Silver) and haven’t had any issues with the heat generated, although I am only driving them around 310mA using an LM317 (Chanzon specs 300-350). With the Chanzon star-shaped heatsinks, you could probably max them at 350mA without any trouble. (If you…
