I want to have an equal comparison, apples to apples. I'm looking at 850nm IR lights. With regular lights, a 60W isn't as bright as a 65W. I'm told by one IR seller his 3 watt is brighter than a 5w by company X. So I went to mW as in milliwatts and again am being told, dont look at the mW because company Z sells a 1070mW that's brighter than company W 1500mW. Watts, mW, Lumens, Come on, there has to be a way of knowing which companies IR light is shining brighter than the others. Is there a simple way to compare IR illuminator brightness or output?
