3pcs green/blue/red "5mw" lasers eBay






Those are nice entry level Lasers for the price...
At least you will have 405nm...532nm and 650nm
of laser wavelengths.

eBay lasers are terrible in quality... enjoy your lasers while you can
 
I have some of those cheap 5mW eBay lasers in the
shop that I bought a few years ago and 90% of them
still work fine.

If you know that you won't get EXACTLY what you are
told by the seller you can't go wrong for 3 different
wavelength Lasers for under $11 with shipping included
from China as your first Lasers.

Yeah. These are pretty good! THe violet ones are about 70mw, the red up to 100mw, and the green ones can get up to 50mw!!!
 
You are right about the other two but I've never had
a cheap 5mW red measure higher that 12mW..
and the greens are with a lot of IR..


Jerry
 
Yeah the greens are almost 50% IR 50% green... dangerous

EDIT: 532nd post! :p

I bought a 3-pack like this on eBay a few months ago. They look just like yours, 3/$12 plus $4 shipping. (The higher price is because I wanted it shipped from the USA.) They work fine and have proven durable. They say eBay is fine for inexpensive items like this.
 
But very dangerous due to way overspec output and IR dangers. Not to mention, a lot of eBay pens die after a few weeks :whistle:
