   Less common designs may have 3014, 4014, 7020, 8020, or other SMDs. In addition to the LED SMD type, the quantity of LEDs per meter is also an important factor in determining the overall power and brightness. [5] LED strip lights most commonly operate on 12 or 24 volts of direct current from a power supply, sometimes referred to as a driver ...
