I'd be happy to compare with any light that I can get my hands on. The Solarstorm x2 looks like it puts out a lot of light, the MTBR review said it was maybe 1000 lumens. The picture looked impressive, but the pictures always look impressive. Cameras don't see the way we see. They have ISO, we don't.
Anybody in the NYC area that has one and wants to do a side by side?
