Though watts measured the amount of power used, people started to associate them with level of brightness, because everyone knew a 100-watt bulb was brighter than a 40-watt bulb. Why is there so much confusion between watts and lumens? When incandescent lights where the primary light source used in homes and businesses, all were measured in watts. In the world of LED, a 26-watt bulb creates the same amount of lumens. An incandescent bulb that uses 100 watts, for example, produces about 1600 lumens. However, you can estimate the amount of lumens a particular watt bulb would produce. This would be like comparing a pound of apples to a gallon of milk – the measurements are completely different. Lumens and watts measure different things, so they can’t really be compared. If you need a particular number of lumens per square foot, and know how many lumens the light produces, you can install or purchase the right number of lights. Most facilities have a minimum requirement for proper visibility, and you can only calculate how many lights you need if you calculate in lumens. Lumens are a particularly helpful unit when trying to calculate how many lights to buy for your facility. That is why LED lighting is measured in lumens. Now that the industry has so many energy efficient lighting options, more wattage does not actually mean more light, unless you are staying within the same type of light bulb. Traditional incandescent bulbs were measured in watts, which showed how much power they used. Measuring the brightness of a light is more important than measuring its power. The higher the lumens, the brighter the light will be. In other words, lumens measure the amount of light your LED light puts out. The term lumen means “light,” which makes sense when you understand what this measures. This is different than Watts, which measure the amount of energy in a light. In LED lighting, lumens measure the brightness of a light. Here’s a closer look at what this term means, and how it affects your lighting choices. Lumens are an important measurement in lighting and understanding them will help you choose the right lighting for your needs. In fact, on the information panel of an LED light, lumen ratings are often listed first. 7180187.When shopping for LED lights, one term you will come across often is the term lumen.
