Non-dimmable LED Driver
How Many Lights Can I Connect To My Power Supply? Sep 27, 2018

When operating LED lights, you need a Class 2 LED Power Supply to convert your standard line voltage (120V or 277V) into low voltage (12V or 24V). This allows your lights to function properly.


To figure out how many lights you can power with a single power supply, look to the minimum and maximum wattage ratings. The led power supply's minimum wattage rating tells you the smallest number of watts it needs to power in order to work. The maximum wattage rating, as you probably guessed, indicates the largest total number of watts a transformer can handle.


There are two kinds of power supply you can use – electronic and magnetic. Dimmable Electronic Power Supply are cooler, quieter, and more compact than magnetic transformers. But, electronic power supply can't power more than 300 watts, while magnetic ones can power as much as 1,200 watts.


When using an electronic power supply driver, the total wattage of the light fixtures connected to the transformer should be less than or equal to the maximum wattage rating. For most magnetic transformers, the total wattage of the lights you connect shouldn't be more than 80% of the maximum wattage rating. This is because the cheaper design of many magnetic transformers can cause additional power loss.


So, if you want to connect eight led strip lights to an electronic transformer, and the lights use 20 watts each, you would need a 160 watt power supply. (8 lights X 20 watts = 160 watts).
