I wanted to do a test.
Too many blade brightness photos don't adjust the camera settings, so the blade is over-exposing the camera sensor to white (which isn't what happens in-person).
More importantly, I have a nicely textured carpet, so I can gauge how much light the blade is throwing onto surroundings.
So I took my new sabers and did comparison pics.
These were taken in a standardly-lit room, with sunlight & artificial lighting, but I dropped my camera's ISO as low as it could go (100...this means it demands more light to pickup the image of something, and is less likely to be overwhelmed by saber brightness), and I dropped my camera's exposure compensation as low as it could go (making the picture darker, but making the saber brightness less likely to overload the sensor).
This makes my photos look like they were taken in a dark room, but they were not.
I think it's clear from these that the standard blade is throwing a bit more light onto my carpet & ruler than the Ultraedge (get the pics into a photo program and compare them side-by-side, horizontally, vertically, in segments etc). Does standard look brighter to the eye? Who knows, since I don't have 2 of the same saber to do side-by-side with differing blades.
Saber: Archon SRD/FOC AS/BuckPuck, fully charged Li-Ions
LED: I assume using 2-dies of a 4-die 10W RGB LedEngin
Blade: Standard mid-grade
Camera: ISO 100, lowered exposure, daylight; and yes, the FOC SRD is fairly blue (non-FOC is greener)

Same as above, but Ultraedge mid-grade:

Saber: Prophecy CG/BuckPuck/no sound, fully charged Li-Ions
LED: I assume a 5W LED
Blade: Standard mid-grade
Camera: ISO 100, lowered exposure, taken later in the day than the SRD. The color is a little blue in this pic near the emitter, the brightness was giving the camera some trouble:

Same as above, but Ultraedge mid-grade:
