The Spyder III Pro Arctic is an incredibly powerful laser- one of the most powerful in the world that you can legally own. This laser can put out a pilots eye from 10,000 up in the sky (flying the plane of course) feet from the ground if pointed up at the plane.
There is even a warning not to do this very thing (point the laser at planes or helicopters)! Imagine what all that power can do consolidated and compressed into a "saber" blade?
You don't have to imagine; wicked lasers did it, and for under 400.00 (299.00 for the Spyder laser device and 100.00 for the LaserSaber attachment piece).
The green version is a bit more expensive even though it looks like it's less powerful (from wattage). The reality, however, is that the green laser is incredibly powerful (much more so than the blue laser) and the only one to break the earths atmosphere (from the ground) and push on into space. At close range this laser can cut/melt a CD or even a Velcro strap in seconds.
With all this cool laser power out in the open, nobody thought to "cage" it for a more powerful piece of harnessed light. This is precisely what the Laser Saber attachment does. It pushes the light into a diffuser that pushes the laser light up the blade evenly. The laser light inside the sabers blade can inflict some serious damage and even death... So no sword play!
This laser, even in sword/saber mode, requires protective eye wear- now that's a powerful light. You can't actually stare into the swords brilliant light with the naked eye unless you want to risk damaging your vision.
This device has to be seen only by those with protective eye wear! The light can blind instantly and can set fire to skin so be careful! The unit does come with these glasses. If your planning to showcase your bad boy laser saber make sure you have enough glasses for everyone watching!
