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 ?
