Blue Lasers vs. Red Lasers: Which are Better

Here I compare powerful red and blue lasers, showing the pros and cons of each. Both make great burning lasers with enough power behind them. I built the 1W blue laser in the video, but the 200mW red laser was bought from here: I originally wasn t going to make this video, but I had a lot of requests for it so I went ahead and made it. Y all are too lazy to watch the other two videos in the series and make a conclusion between red and blue ;)
