So, according to the relative brightness calculator, a 532nm laser is 13.57x brighter then a 450nm laser of the same power. However, if I switch to beam brightness, and turn on mesopic correction, the blue laser's beam is actually 1.31x BRIGHTER then the green laser, when they are both 5mW. At 1W for both, the green laser is 1.17x brighter, and that increases with the power of both lasers. Is that even close to correct? A blue laser having a brighter or nearly as bright beam as a green laser with the exact same power just sounds so wrong...
