haha no problem. For future reference, as it really isnt a problem, my screen name is KRNAZNBOY, which can be broken into 3 parts, KRN-AZN-BOY. KRN extends to korean, AZN extends to Asian, and BOY is just boy. Therefore, you get "Korean Asian Boy"

Just a bit of story on my name lol. Still get kicks out of it. Dont want to change it though.

Equal brightness is NOT the same as a good color balance. This is speculation on your part, and it is wrong.
Well im sorry sheesh. Care to explain as i do not understand. I am not experienced with rare laser wavelengths or color balances.

Some wavelengths excite cones better than others. Refer to the graph in the video above. The types of cones need a specific excitation ratio to get white, and again, this is not the same as brightness.

As an example, DPSS 473nm is clearly brighter than diode 445nm of equal power, but 445 is closer to the peak of the blue cones' sensitivity, so you actually need less of it to make white. 473 is further off the peak, so you need more of it. It appears brighter because it excites other cone types better than 445.
