Hello ı have 1w 445nm blords laser , my laser is sell and ı will buy new laser ;

3w Blue 445nm or 400mw Green laser , Do you have a video comparison (Beam daylight/night , burnmatch)

And what is G2 lenses , How it works , Laser can be obtained is it necessary?

Maybe someone will come along with a video (or pic) comparison but in the mean time here is a website that can show you what the relative beam or dot brightness between the two:

Beam: (445nm 3000mw) vs. (532nm 400mw)

The above shows that green beam (presuming you mean a 532nm 400mW) will still be 1 1/3 times brighter than a 3W 445nm laser.

Dot: (445nm 3000mw) vs. (532nm 400mw)

And this one shows that the green dot (presuming once again you mean a 532nm 400mW) will be over 2 3/4 times brighter than the 3W 445nm laser.

A G2 lens is a special chemically treated low loss beam correcting lens. It is not as good at beam correcting as a 3 element lens (being there is only one lens) but there is much less loss of power when running a laser through it. A 3 element lens will typically cost you 25% to 30% of the power output. Someone will probably have a better explanation but till then this is what I can tell you.

Definitely a 3W 445 would be a good choice to buy. Great with Burning and bright at night too. A 400mw 532 won't burns that great. :wave:
