With LED lights, no ballast, with the power switch on the line,
General LED advertising lamp box, you can use the regulated power supply for the LED advertising lamp box power supply. The power of the regulated power supply matches the total power of all the advertising lamp boxes, and the power of the regulated power supply can only be large, which can be higher than the total power of all the advertising lamp boxes, and can not be small and the voltage must be the same.
With LED lights, no ballast, with the power switch on the line,
The most convenient way is: all advertising lights LED lights module all in parallel together, and then connected to the regulated power supply.
