Erstmal Hallo :D Leider ist mein Englisch sehr schlecht ;).

Ich habe mir den Laserglow Galileo gekauft. Der hat 4,5 mW. (https://www.laserglow.com/GGA)
Ich möchte mir nun einen kaufen der etwas stärker ist und wo man den Strahl in der Nacht noch deutlicher sieht. Ich habe mir diesen rausgesucht: Laserglow Aries 20. Er hat 20mW-34mW. (https://www.laserglow.com/GAR)
Meine Frage ist der Strahl von 4,5 zu 20-34mW deutlich besser in der Nacht zu sehen?
Und brauche ich eine Brille? Ich habe gehört 30mW währen gerade noch so die grenzen um einen Treffer ins Auge zu bekommen ohne das etwas passiert?



First Hello : D Sorry my english is very bad ;).

I bought the Laserglow Galileo, 4.5 mW. ( https://www.laserglow.com/GGA )
I now want to buy a slightly stronger and where we see the beam at night even clearer to me . I have picked out these : Laserglow Aries 20, 20mW - 34mW. ( https://www.laserglow.com/GAR )
My question: is the beam from 4.5 to 20-34mW a big difference at night ?
Do I need a pair of glasses? I heard 30mW are the border to get a hit in my eyes?

Hey, welcome to the forums. First off, your English is fine. It's easy to understand what you mean.

30mW and up is pretty visible at night. I would however get a 75mW+ Aries laser as you get a lot more power for the money you're spending on it. 5mW and up is already considered dangerous for your eyes, so I would recommend getting a pair of safety glasses with the laser.

Take a look at this calculator that one of our members (RHD) made. It's very easy to calculate how bright a certain power or wavelength is compared to another.

If you have any questions, feel free to ask.
