By these answers that is not a great website it seems if you want an answer for your scientific question.
The answers that you quote are vague, terms are undefined, the information is incomplete and some information is wrong. In other words: the question is not very scientifically answered. One example: light from a CFL tube can be perfectly white, even very high CRI, and yet the spectrum is a bunch of discrete peaks, most wavelengths in the visible spectrum are prety much absent.
Black is the absence of all colors, they are all absorbed into a black body and nothing reflected hence no color to see. White is the presence of all colors, nothing absorbed.
Hey I’m just doing the best I can with what I have to work with, I’m not even close to a scientist. Like old Forrest Gump, I’m not a real smart man.
I’m just throwing out some ideas against the wall to see if anything will stick.
Back to the ole’ drawing board I guess for me…… …
But I truly am interested in the true definition / meaning of white light.
If it is not…. “White light is a balance of all the wavelengths (colors) of visible light: Red, Orange, Yellow, Green, Blue, Indigo, and Violet, the same colors and order of rainbows”. …… what is it?
White light is defined as the complete mixture of all of the wavelengths of the visible spectrum. This means that if I have beams of light of all of the colors of the rainbow and focus all of the colors onto a single spot, the combination of all of the colors will result in a beam of white light.
At some point I wonder if it really matters that we understand HOW white light is made, I mean, after all, WE are not the ones making emitters or the phosphor that drives them. We merely buy what is available to us, which oftentimes is not the best tint. Not to mention that WE don’t control the AR coatings that go on a lens and more often than not skew the tint of our prize emitters. So, is it us that needs to understand, or the people that actually have control over the items we buy?
Seriously, teacher, we already have ONE ROCKET SCIENTIST here, he can’t get it right either apparently… look sharp, ie: focus and diligence achieves the ultimate success. Or does it? Luck favors the blissfully ignorant.
Hope it will be able to outperform in throw Nitecore MH20GT which is almost identical in dimensions (except max diameter)
Or maybe its just a wishful thinking?
