Compare the light given off by a good CFL, like a 26-watt GE daylight (equals a 100 watt bulb) to an incandescent 100 watt and I will be dipped if I can't see a LOT better with the CFL.
It don't add. The physics. 2+2 = 9,213,616
A hundred watts, right? Well how many watts, the percentage, is given off as infra red with an incandescent light bulb? You can't end up with forty percent of the energy expressed as heat and a hundred percent more added on expressed as photons.
Some bright individual has to work on lumens philosophy and translate the current gibberish into rendered light quantity. Of all the disciplines I have browsed this one is the most muddied, malleable and controversial. Someone casts out a number. It and the other hundred billion "lumen" claims are as valid as your everyday 3 dollar bill.
I buy a 600 lumen light and compare it to another 600 lumen light. I will kiss your... well anyway, they do not emit the same amount of light. Take your pick doesn't matter if they are 3,000 K or 6,000 K
I have seen 300 5-meter LED strips that do not give off as much light as my dinky 9 watt daylight CFL. But they are rated for more lumens, and more watts. I don't mean SPREAD OUT. I mean coiled up strips.
So as far as I am concerned learning or understanding what some of the PhD knotheads express as visible light is as meaningful as trying to learn Xhosa Click Tongue Language to aid in business meetings.
Damn! It's brighter! We'd better assign a higher number to it! This only is meaningful to the consumer if people are a) intelligent b) ethical
Crankiness of the day expended.
