Well, the spacebridge in DOTM, was kind of a light/energy beam, though not the same thing. The Allspark also manifested a lot of light related surges, and also can't be counted for laser fire. Blackout's pulse-wave, was spacey enough, and awesome. If I'm not mistaken, when Jazz, Ironhide and Ratched all attacked Brawl/Devastator, Jazz used his shield, and something blue bounced off of it -- or I'm just confusing it for Brawl's energon oozing stump. I think Even Megatron shot something blue at Prime, with his fused hands-cannon, and perhaps even in ROTF, when firing at Sam.
