How To Calculate Amps For Led Lights. This calulator will help you figure out the proper resistors needed to safely hook up one or more LEDs to power supplies of various values. For most light sources and LED spots the power consumption in watts W is given.
For example the Waveform FilmGrade LED strip power draw is 55 watts per foot. Determine the voltage and watts per foot or meter for the LED strip. A 100 square foot living room that requires 10 to 20 foot-candles will need between 1000 and 2000 lm.
A simple formula for calculating amps is to take the watts and divide that by the volts.
In this example the transformer will see a load of 47 watts. Show activity on this post. LED 6 Lamp T8 STINGRAY 6XL Highbay Fixture 132 Watts Frosted Calc View Product. We stock all of our LED Tapes for next day delivery.
