The R5 is nowhere near the 'Newest And Brightest Of All.' The XM-L (or XM-L2 when it comes out) is probably closer to that designation. It may be the brightest you can safely run for under 5 min with a heat sink that size, but that's it.
Oh, and that 'test' of how bright the leds are is flawed as the leds point all of their light straight out of the end of the lamp. The stock 921 shines light in all directions, which is where the reflector comes into play. If that was a valid test, they'd have a reflector shining all the light from the bulb onto the sensor.
Sorry, I hate marketing gimmicks. Especially when it comes to led lighting.
