We bought these for a project that got scrapped, good, extremely bright panels.
Chinesium Description: “The lamp board is made of high quality lamp beads and aluminum substrate. The power supply interface is MICRO USB, which is convenient to connect the ordinary mobile phone charger and mobile power supply. The set working current is relatively large, with a current value of 430mA~470mA, which can ensure sufficient brightness and better heat dissipation design, so that the temperature is not too high. The matched current limiting resistor is 1210 large package, instead of the common LED”
Translation, 5730smd LED modules (20 per board), wired up to a micro usb female header. Carrier board is all aluminum for great heat dissipation. Very bright, weighing in at 7.70 grams, they are very light.
They can be powered by ordinary wall USB charger.
no enclosure to these, (But hey, you have a 3d printer, get on tinker cad and whip something up!)
WARNING: DO NOT STARE DIRECTLY INTO LIT PANEL AS THEY ARE SO BRIGHT YOU WILL THINK YOU HAVE GONE BLIND!
