Default Difference between 75 and 95 mW

Hello guys,

First of all i want to apologize if someone was already asking about this but i havent found satisfying aswer.

The thing is im about to buy a new laser, i already had an 50mW unit from CNI.
This time im thinking about 75 or 95 mW from Dragon Lasers but i cannot decide which one to get.
I dont really want it to burn things and do stuff like that, the thing im interrested about is the beam itself and its visibility.
So the question is, is 95mw beam is alot brighter than 75mW or the difference isnt so noticeble and i should rather stick with 75mW?

Thanks for help and sorry for my english.

in my experience, the difference it negligible. many lasers have powers that go between the two. unless your looking at them side by side you shouldnt be able to tell a difference

What wavelength are the 3 Lasers are you referring to...

532nm, And what about the terms of safety, i know both are dangerous but how whats the difference?
With that 50mW which was rated propably slightly higher i havent used goggles and nothing bad happened.

The statement that "nothing bad happened" does not mean
that your 50mW Laser is not dangerous... IT IS DANGEROUS....
You should be wearing Laser Safety Googles/Glasse when
operating it inside.

It is a well known fact that operating any Lasers > 5mW should
be operated while wearing the Laser Proper Eye Protection.

As to the visible light intensity difference between a 75mW and
95mW 532nm Laser that may be different from person to person.
You may see a slight difference (if the two Laser are actually 75mW
and 95mW respectively) in the intensity of the two beams or you
might not... you are only talking about a 20mW difference...

Thats why i said i that i know both of em are dangerous, the way i mented it was more like if i should treat +40mW laser much more carefully than my previous 50 mW unit.

Not really, they are both just as dangerous... Think of it like this...

If you shoot yourself in the head with a revolver or a .50 cal you will still be dead.
the .50 cal will leave less of your head intact but regardless you will be dead.

Is a revolver less dangerous than a .50 cal when shooting yourself in the head? I would say no.

Get the 95mw not because it's a little bit brighter, but because you'll get rid of that nagging question of 'should I have bought that 95mw laser' you'll be happier you did.

Thanks for help everyone was really helpful but one final question.
How is Opto compared to Dragon lasers in quality of pen laser units?
I heard Opto's RPL series is superior but how about pen lasers?
