I have every colour of the Sanwu Pocket lasers and like them all. I like that the red laser and violet laser are single mode. I like the blue and green lasers too for the colour. I was using a 50mw 520nm pocket laser for astronomy, but I replaced it with the 5mw Laserland pen style 510 laser (see other thread). I also like that the violet laser causes fluorescence and it is really good burner too (focuses into small spot). I am a bit afraid of the blue and violet lasers for safety reason (high power and blue and violet bother my eyes after awhile). I have safety glasses, but accidents can happen.

I see, I'm leaning more towards the cyan ones then. I envision using them on night time hikes and don't necessarily want something too powerful because I likely won't be using laser safety goggles. (Will be pointing up at the sky or other distant places)

Before you buy any laser over 5mw you need to have laser safety glasses that attenuate the wavelength you will be lasing with.

Yes I have a pair of Sanwu red and another pair of Sanwu green safety goggles. From what I've read, I didn't think they'd be too necessary for a lower output lasers (sub 300mw maybe) if I'm using it outdoors and away from reflective surfaces? (Correct me if I'm wrong)

Well any laser above 5mw can cause issues with your eye if you look directly into them. Green lasers tend to be safer in that they appear brighter and you are more aware of the intensity of the beam. Violet and red appear less bright at same power levels so you can think they are less dangerous (not so). Also blue and violet light can cause macular degeneration. I have seen the effects of bright blue and violet light when I close my eyes and it takes my eyes a little time to recover. Also, accident can happen quickly so better be safe then sorry.

If you can be 100% certain that you won't get a specular reflection or be in the path of the beam then you should be safe, however I would not view a diffuse reflection at point blank either or on the desktop without wearing the laser safety glasses.

You can also use the laser safety glasses to view your spot on the desktop that you otherwise couldn't see because of the bright splash, so the laser safety glasses are a useful tool as well to see what your collimating lens is really doing.

Also you said you were going to use the lasers at night hiking so I doubt you will use safety glasses in the dark hiking.

Yes, I use my od3 glasses for indoor use. I decided to go with the 150mw 520nm pocket laser. I hope it comes out well. Thank you guys for your help. I treat lasers with caution and a lot of fear so it should be alright.

I don't have personal experience with them, but I was considering them when I was looking
