Hi,
I have tons of 450nm and 445nm builds and there the most bang for the buck i love em.
Out of the 450nm diodes ill take the PLTB450B over the M140 any of the week due to the constant efficiency i have encountered with them.Every one i had is well over 2+W's some M140's don't come close. 532nm sounds great ill have to check it out thanks buddy or even a 520nm will do . That might be pretty cool in this host my most concern is heat but i like the sound of a high power diode in this little full copper host,.
