One of the things I really love about my screen used helmet as opposed to my Sideshow replicas is that it has real lasers in it as opposed to LEDs. For those of you that costume, real lasers probably aren't the best choice, but my helmets are pretty much for display only so I am planning to outfit them all with the same lasers as are on my original helmet.
From what I can see, KNB used 5MW laser modules that have a brass housing that is 8mmX13mm and include a current control driver.
Here are the lasers in my Berseker helmet:
These are the closest I have been able to find on eBay.
