Does Lumens equal brightness?
A 60 Watt incandecent light bulb has approx. 750 lumens (according to the box) and a 65 Watt incandecent floodlight is approx 665 (plus) lumens. I was shopping for a LED replacement for the floodlight and I read where manufacturers state that their bulb was equivalent to a 65 Watt incandecent flood, but depeding on the manufacturer, they were only 70, 115, 190, 240, ect. lumens. How can all these be equivalent to the “brightness” of a 65 Watt incandecent flood? Does the “Par” have anything to do with this? (what is it?)
I’m basically looking to replace 5 incandecent 65 Watt flood lights (can track lighting) with something of equivalent brightness that is dimmable and more energy efficient.
A lumen is a unit that represents how much light the bulb puts out
A watt is a measure of how much power(voltage x current) the light bulb uses to make the light.
So if you have a LED bulb that’s equivalent to a 65 watt incandescent bulb that means it puts out the same amount of light as a 65 watt incandescent bulb, but with much less energy use. I think the manufacturers made a mistake on their light bulbs. When you consider that a pretty good presentation projector is about 2000 lumens….yeah. You also might have confused lumens and nits. Nits are another commonly used measurement of luminance. Nits, however are used to measure direct light, not refracted or reflected light. There’s also a chance that the manufacturer confused it with another unit if luminance.
