Indicates how much power the light source draws from the mains, in other words consumes electricity. Please note that different light fixtures produce different amounts of light (lm/W), so the input power is not to be used as a measure of the amount of light or to compare the light output of two different light fixtures.
The power used by the whole product (not just that of the LED) (W) is indicated in every LIMENTE light fixture. Therefore, it’s easy to choose the correct power supply as follows:
Add up the power of all the light fixtures connected to the same power supply, e.g. 5x4W=20W. In this case, the power supply should be of at least 20W. Please also pay attention to make sure the power supply and the light fixtures have the same voltage (12V or 24V).
