Wattage refers to: minimal amount of energy necessary to create light; heat output;

The higher amount of lumens, the brighter the light will be. On average, an incandescent bulb produces around 14 lumens per watt, compared to 63 lumens for energy saving compact fluorescents (CFL) and 74 for LED bulbs. A specification in lux tells you how many Lumens (total light output) you need given the measured area you are trying to illuminate. Lumens are used to measure the total output of a bulb and you’ll find the measurement on the box of the bulb or the bulb itself. Waterproof Marine High Intensity LED Flood Light. Dimmable from 100% to 10%, these bulbs have a 200 degree beam angle to cast light in a wide area. Thanks to older incandescent light bulbs, people are used to looking at Watts to determine light output. Watts measure the electrical energy required to light a bulb, while lumens are a measure of the brightness of the light produced.
