Under normal circumstances, the output voltage of the LED lamp is 3 ~ 12V.

LED lamp beads, in fact, is a light-emitting diode, loading a certain voltage and current will emit light. Generally, the voltage of a single LED chip is about 3V, and the current is 30mA, and the voltage and current of the LED lamp beads are mostly determined by the series and parallel relationship of the LED chip during the LED packaging process.
There are generally two kinds of voltage on the market, 12VDC and 24VDC, of which 24VDC is more for them. This is mainly related to the series and parallel circuit of your LED lamp with lamp beads, if you are a series circuit with 3 lamp beads, the driving voltage is 12VDC, is 6 lamp beads, the driving voltage is 24V, of course, the circuit to add the current limiting resistance.
led lamp output voltage is 12V, 36V.
led driver output voltage is 12V, 24V.
