Well I got that mixer light in a few days ago and tried it out last night; it works great and is plenty bright, almost too bright. My only complaint is that it could be longer; it's definitely on the short side but the brightness helps make up for it.
This was taken with my Nexus 4 with the flash off and the main house lights in the room off(only a couple of can lights over the stage were on).
It also should be noted that the LEDs produce very white light as opposed to the blueish light that many cheap LEDs produce.
I may try taping a piece of paper over the light to dim/diffuse it some; I'll post back if that helps. IMO the light is well worth the $20; if you need one go buy it.
