    The batteries' struggle

    I recently bought a 532nm green laser from ebay, and it came without a battery. I tried it with my ecig's 18650 3.7V Li-ion battery and it seems to work like a charm, although I later found out it's supposed to be used with 2 16340 3.7V batteries (the contacts are a little loose so sometimes I...

    Tips on how to use my new laser safely?

    The laser was obviously advertised as <5mW, the seller said it should've been around 1.5W (unrealistic for a green laser given the inefficiently of using IR lasers to make green light) and the sticker on it says it's under 5000mW so I basically have no idea until I shove out the 300+ dollars for...

    Tips on how to use my new laser safely?

    Thanks for the advice! All of my siblings are over the age of 14 so I'm hoping that if I tell them not to play with my eye-blowing death laser if they don't wanna become permanently blind they'll follow my advice. Regardless I think I'll buy an ammo case regardless, just in case... 😂

    Tips on how to use my new laser safely?

    Hi all! This is my first time posting here, I've been following this community for a while (got to know this thanks to styropyro) and yesterday I finally got my first laser "pointer" delivered. It's a green (532nm) class 3 laser and the sticker says the output power is "under 5000mW" (duh). I...
