Sanwu Challenger II. 4.5w. 470nm blue laser 

Great video.

This laser has NUBM07 diode that typically emit 465nm light, output power around 3500mw

I just purchased the multi-operation version and now I'm wishing I just got the single. It's coming in the next two weeks.

Do you actually need to put the goggles on when you are pointing it outside? i got the Challenger 2 6w, so i am just wondering. Also, i got the bright blue version.

এই ভিডিওটা যে এই জেলাটি দেখিয়েছেন লাইটের দাম কত এবং এটি আপনি অর্ডার এনে দিতে পারবেন আমার বাংলাদেশি টাকায় কত টাকা

I accidentally messed up my Challenger 2 lens, so I am wondering if I need a type of glue to stick my new lens in my laser

Where did you get that??

The edits take away from the content of the video
