![]() Incandescent bulbs, for example some modern LED light fixtures can produce 800 lumens It is very interesting to compare modern lights to So if you want the same amount of light but want an LED light source, you would look for an LED light that produces 800 lumens. The chart above is very useful in understanding theīrightness of incandescent bulbs. – LED or CFL) will not produce a valid comparison. Light per watt, the more efficient modern sources are able to produce aĬonsiderable amount of light using a very small amount of electricity.Ĭomparing the wattage of an incandescent light bulb with a bulb using aĭifferent light source (e.g. While less efficient sources wouldn’t necessarily produce as much There are light bulbs with many different types of light sources on the market,Īnd there is a big difference in the energy efficiency of these different Would give a good idea of the difference in brightness between those bulbs. Number of lumens per watt), so comparing the wattages of two different bulbs MostĬonsumer incandescent lights have the same efficiency (producing the same For a long time incandescent bulbs were the standard.ĭuring this period their brightness was often spoken about in Watts. This misconception about watts comes from the era of ![]() Why were Watts used to describe brightness? If you are interested in learning about the brightness of a light, it is important to ask how many lumens the light produces. Watts are a measure of the power used, not the amount of light produced. This is a common misconception, and it isīased on a misunderstanding of what watts measure. Watts our LED lights are, they often assume that because they are low wattage We often speak to customers who are surprised by how few
