While their rated raw lumen outputs are fairly close, what I don't see on Black Oak's site is a [email protected] measurement, which tells you how effective the optics in the light are at harnessing the light output of the LEDs. These Rigid Duallys throw out 721 lux at 10 meters, and since the Black Oak LEDs look like they use fairly generic optics, I'd argue that the Rigid's have an edge on overall brightness and beam pattern.
