i was not saying they were no good. as a matter of fact, when tested side by side by MIGRO, the p series is a little better, . i was just pointing out the name brand of the diode and driver as some boon to a name of the newer light.
im actually sort of into electronics and such, and im not so sure the difference in one diode and the other is significant really, but the names carry some weight in the community, so to get anyone to even look, i tend to mention it.
