I contacted Sanwu and they told me that the 455 nm 150 mW is very close to 445 nm 500 mW but I haven't got any pictures.OIC
I'm sure a mod will come along and delete the other at some point.
I wouldn't expect 150mw of 455nm to be very bright but 150mw of 488-492nm looks great, have you thought about a Sharp GHO4850B2G ?

Sharp 490nm GH04850B2G 55mW Laser Diode Datasheet The micro-printing around the diode window is SB303B292, just like the one in this photo, Jordan. I have preliminary results and I have never been so happy to be proved wrong. I tested the first five at varying currents from as low...laserpointerforums.com
