Well, I like those renderings (I am still not getting the icecube idea ^^) of SFMAT, great!

Though, I am still confused by his A7/bulb lets-intermingle-it logo. Honestly, its hard to look at - I mean, it makes me look away everytime I want to focus on it: maybe its the coloring (try completely white ellipses and another shadowing, plus, make the 7 black or dark grey) or the shape: the ellipsoid-chain of the bulb holder has a completely divergent swing than the streched ellipse of the "7" PLUS the orange 7 is also introducing a whole new viewing curve to the "reader" (+ shadow direction). So, I dont know why, but it makes me feel.. awkward. So, maybe if you add some more order to the view axis of your logo (the logo.. not the rest!) and the composition with the label (acknex 7), you could improve your logo a lot! (I think)

I vote for that one or two logos that make(s) the whole product more serious.
