First, I am an idiot. None of this came from my brain. I picked Henry's brain which is much better than picking his nose.
Folks asked before what lumen output is on the HDS monochromic lights (Dark Adaption Red, Hunter Green, Forensic Blue, UV, and Amber). Since these are not measured in lumen output but in mW.
First point to remember here is that the exact same amount of power is going into the emitter with all the HDS monochromic lights. This doesn't change (this is important later in order to confuse you).
So let's muddy things.
If the Dark Adaption Red is 900mW and the Amber is 250mW outputs, then we can assume that the red is brighter, right? Wrong.
This has to do with how your eyes are color sensitive. Here is a chart of how sensitive your eyes are to different colors...
As you can see, your eyes are most sensitive to green (555 nanometers). This means red light needs to be "brighter" or have more mW to appear as bright as green. Same with the other monochromic colors. It may not be easy being green, but you will be seen better.
So, you should be asking yourself "if an emitter is lower in mW output, shouldn't that run longer since the amount of juice being fed to said emitter is the same?".
Nope.
The reason for this is that different materials are used in the emitter in order to get it to generate those specific monochromatic colors. The efficiency of these materials for each color is different.
Power (being constant) x efficiency of the emitter converting electrons to photons = mW
mW X eye sensitivity = how bright it appears.
So, the Dark Adaption Red emitter is much more efficient at converting electrons to photons... but in order for it to appear (your eye sensitivity) as bright as another, you need a lot more of it.
