Here is the brightest handheld laser that I have ever built! As you can see in the video, the output of the laser easily illuminates a room, as well as ignites nearly anything in its path.

Also, thank you everyone for helping me reach 100,000 subscribers!! Making videos has been an awesome journey and I plan to post more videos before long!

Here is the laser diode I used: Laser Shop

I had the laser casing made for me by the talented machinist who goes by “Ehgemus” on laserpointerforums.
