The lamp board adopts high-quality lamp beads, the substrate is aluminum substrate, and the power supply interface adopts MICRO USB, which is convenient for connecting to ordinary mobile phone chargers and mobile power supplies. The set working current is relatively large, the current value is 430mA-740mA, which can ensure sufficient brightness, and has a better heat dissipation design, so that the temperature is not too high. The matching current-limiting resistor adopts a 1210 large package, which is not an ordinary LED night light single 0805 small package resistor, and has a long service life.

Supply voltage: DC4.5-5.5V (DC voltage)
Power supply interface: Micro USB female socket/+- solder joint welding external lead
Luminous color: white light

Rated power: 
8 LED lamp beads about 8*0.3W=2.4W
12 LED lamp beads about 12*0.3W=3.6W
16 LED lamp beads about 16*0.3W=4.8W
20 LED lamp beads about 20*0.3W=6.0W

Note: A single LED lamp bead is 0.3W, and each column of lamp beads is connected in series with a current limiting resistor,
Actual power may be less than rated power.
