WebHow do you measure brightness of solar lights? A lumen measures the amount of light that comes from a bulb. It refers to a light bulb's brightness, intensity of light and visible light emitted. A standard 40-watt (40W) bulb is equal to 400+ lumens. Typically, the higher the wattage, the higher the lumens, and the more light output.

WebWatts work hand in hand with lumens to predict how much brightness your LED light would emit in a specific watt. A lot of LED lights use the term watt equivalent. When you see a label that says 100-watt LED equivalent, it doesn’t mean that it actually uses 100 watts.
