The green one I have is just a 200mw 532nm pen I got off the net, can pop balloons and such but call me Tim Taylor - Gotta Have More Power!!! lol I really love lasers and I want to just be able to burn through some small things like cd sleeves, light fireworks from a few feet away and just random fun stuff but definately with proper safety goggles and responsibility. I have been looking on the net for days for lasers and found the lpf forum. Been reading a lot of laser stuff and your laser looks great for me!!!
