If you ever plan to lead a PowerPoint presentation projected on giant white board orbiting the Earth (we'll leave the logistics of that one up to you) there's only one laser that will get the job done -- Wicked Lasers ' S3 Krypton. The Guinness Record-pending laser produces about 86 million lux and can be seen from up to 85 miles away, well beyond the edge of our atmosphere. Of course, at roughly 8,000-times the brightness of the Sun, serious safety precautions are needed when operating the S3. Goggles are a must (and bundled with the handheld laser), while sensors and a microprocessor regulate current to keep the tube of aluminum from overheating in your hands. The top end model is available now for $1,000 but, if blinding astronauts isn't on your agenda, lower-powered versions can be had starting at $300. Check out the video after the break.
