HELP. For BEAM: Violet/blue 200-300 mW or green 100 mW?

Hi guys. I am new in this question. I like violet and blue lasers. But I doubt, that I can see their beams at night. And it is important. I live in the city with seaport in Baltic sea, so a climate little bit damp.
What to choose near 80 $? Burning ability is not strongly important. The main thing the biggest visibility of a beam.
What violet/blue laser is better?
1) 405nm 200mW Devil Cyber 405nm - 200mW Focusable Violet Laser Pointer
2) 405nm 300mW New Arrival 405nm 300mW Violet laser torch /Focusable/Burning [OL-NVL-300] - $69.99 : Zen Cart!, The Art of E-commerce

But there are questions: "O-Like" cooperate with PayPal? There can be lasers defective or weak, therefore the shop has discounted 22 %? I read, that probability of a deceit very much greater.

3) 450nm 200mW Powerful 200 mw 450 nm Adjustable Focus Water Resistant Blue Laser Pointer (Black) with * Laser Pointer * Box * 18650 Battery - Free Shipping
4) 405nm 500 mW Lazerpoint
5) 405nm 1000 mW Lazerpoint

Again the same questions: "Lazerpoint" cooperates with PayPal? This laser is qualitative? Capacity is not overestimated?

Here video about violet beams:
BLU-RAY LASER POINTER RUNNING AT 121 MW - YouTube
200mw purple laser beam - YouTube
200mw violet blue laser beam emitted from a pocket-sized laser torch - YouTube

Or better to buy the green laser 100 mW, (??????? ???????? ?????? 100 ??? (green laser 100 mw) - YouTube) and then expensive 1W 445nm?
What green laser is better?
4) LZCB - CYBER 532nm 100mW Focusable Green Laser Pointer
5) LZSK - Stick 532nm 100mW Focusable Green Laser Pointer
6) LZBH - 532nm 100mW Focusable Green Laser Pointer

Wow... that's a lot of links

First off, you should read the stickies and make an introductory post to the forums in the appropriate section. There is a ton of info here about various laser strengths and visibility in the archived posts that you can get from a few searches... Maybe even info on the models you are asking about.

Cheers!

Hello Wiesel,

A 100mW green will be brighter than a 300mW violet laser. There are threads on the Forum that explain this, there is even a link on here somewhere that lets you compare the relative beam brightness and dot brightness. Also, note that most laser companies are not high quality at all; O-like and Lazerer have been decent, I wouldn't really trust any other cheaper sources... Look around on the Forum if you want help on laser companies, everything's on here

If you want a blue with a tight visible beam, look for someone to sell you or build an osram450 single mode diode build for you. Otherwise go green for max visibility VS power.
