450nm 1W 1000mW Blue Laser Module With Holder For DIY Laser Cutter

[lightfoot500]

Hi, came across these two laser modules on banggood.
they say they are for etching as part of cad system
i see some blue 1000 mw pointers for comparable price, but i wonder if the module would last longer or be a true 1000 mw or more depending on which one was bought?

price isnt too bad i thought.
i wondered how far of a beam it would project out. or whether it was just concentrated at a short distance. would the beam project out over several miles is it my question.
definitly some power available.

12 volt 1.3 amp,, could it be run off a battery or just a wall charger ?

I see those all over ebay too. Don't know about how good or bad the divergence would be. If they say 12 volts and 1.3 amps you could run it off any 12V battery or decent 12V PSU.

I guess these things are over rated. no body is messing around with these ?

Don't know if anyone here has one. They might or might not be good, but you'll need to be the guinea pig
