Since I have a bunch of new models and I'm deciding which to keep or whatever to do with all of them, I figured I'd mess around and take a pic. The full size image is pretty big, but click on it if you want to see this in an 800 pixel tall version where the text is easier to read.



Since the emitters base frequency on all these 'white' LEDs is always in the blue region I figured I'd hit them with an ultraviolet source and see what happened. The Malkoff mod is a couple years old but I've always regarded it as having extremely nice tint and quality, the Huntlight I've had for much longer (was my first LED flashlight I believe) and certainly doesn't exactly light up like the rest.

That's pretty sweet. Now I have to go dig out my blacklight.

Yeah it's interesting to see how the different LEDs of various types and ages react. I expected to see more from the Huntlight, but I don't even know what emitter it has, I just know I've had that light for at somewhere around 4 or more years. They seemed really impressively bright back then too!

I guess I should clarify what's going on since I left a lot out of the original post. Since the base wavelength of these emitters is in the blue, I used the black light (UV, near blue) to substitute that so I could get the phosphors to react without turning the lights on. I just wanted to compare the phosphors to one another.

Is it 100% the same as how they might respond to the emission of the emitter? Not necessarily. Still interesting and easy enough to do!
