People think that LUX and lumens are the same, nlsk1 could just explain it without being a twat.
I am not sure I am experienced enough to explain it for you... I probably need references or something...People think that LUX and lumens are the same, nlsk1 could just explain it without being a twat.
Yeah, you sorta cut that line off short eh?Took this from the original post on that thread
"What this means is that if you put two lights the same distance from a point, and each light provides N photons per unit area at the point, with two lights you will have 2N photons per unit area at the point. Because intensity is a measure of the number of photons per unit area, the light is twice as intense, whatever unit you choose to use. Twice the lumens, twice the lux, twice the footcandles.
An obvious practical caveat to this point comes when using multiple low-intensity light sources. Notice how I stated that the lights were at the same distance? A practical problem with CFLs, for example, is that while you can get 27000 lumens from 10 x 42W CFLs
it's difficult to get them close enough to make them useful.
Well I already know. Now why don't you amaze the kids with your wiki powers because they might not be able to see what you really are.I am not sure I am experienced enough to explain it for you
