Do we plug LED system in the same way as conventional lamps, into the wall outlet?
Since LED sources are solid state devices, they are most commonly powered by DC voltage. In addition, the color changing features of some fixtures require a data line connected from a central controller. Common fixture voltages are 12 and 24 VDC. Providing this voltage requires a power supply or driver. Due to the low power draw, one power supply may operate multiple fixtures. Consolidating many fixtures on one power supply reduces the size of the fixture, the cost of the unit, the number of problematic components onboard the fixture, and the heat build up in the fixture.
