2022/06/03 · Lastly, consider the voltage of the high-brightness LED strip to make sure it will give you the power you need. 110-120V strips that you can plug to the current are more powerful than low-voltage models, such as the 12V and 24V

Why drive current matters. The amount of light (Lumens) an LED emits depends on how much current is supplied. Current is measured in milliamps (mA) or amps (A). High-power LEDs can take currents from 350mA to 3000mA. LEDs vary on their current ratings so be sure to keep track of this when picking an LED and driver.
