WickedLasers has released a "weapons-grade" laser that is rated at 1W of power. The Spyder III Pro Arctic looks like a lightsaber, and according to the company it's powerful enough to set your skin or other body parts on fire if you aren't careful enough. The product is available on WickedLasers' site for $197.97.
And here's the best (or worst) part -- it can set people (or things) on fire. Apparently the laser is so high powered that shining it on fleshy parts will cause them to burst into flames. Of course it's equally capable of blinding people. The retailer warns:
Warning: Extremely dangerous is an understatement to the power of 1W of laser power. It will blind permanently and instantly and set fire quickly to skin and other body parts, use with extreme caution and only when using the included eye protection. Customers will be required to completely read and agree to our Class IV Laser Hazard Acknowledgment Form.
If you're willing to "sign the form", WickedLasers warns you "With greater power comes the need for greater responsibility." (We can't make this stuff up, really!)
