Here are some pics of my new Makoto blade (I just got it today). I quickly put it in my Graflex WIP with Anakin electronics inside just to show how it works. The other saber is a 2005 MR Anakin ROTS. Both sabers have new Energizer lithiums.
The Makoto blade is not perfectly even in color/brightness but is still looks pretty good and bright. You can still see some unevenness when viewing in person. It is not blinding bright or anything like that either but it is much brighter than the MR. I'll have to compare it to my blue Lux Rebel once I get that setup.
These next 3 pics are taken with different aperature settings. The first one is underexposed but shows some of the unevenness of both blades. I'd say it actually looks something inbetween the 2nd and 3rd pic but closer to the 2nd. Also, the camera doesn't really capture the actual color very well. The Makoto blade is more of a lighter powdery blue than the Anakin (more than the pics show at least).
This was done with just the standard MR electronics. I'm going to try overdriving it with a USB2.0 at 1500mA.
