I just got one today from TMart, advertised as focusable and 200mW, reviews say it is probably closer to 70mW.
My understanding is that you can see a green beam even in direct sunlight. Is that your experience? I can't see mine in direct sunlight, so I was curious.
Is impossible to see the beam in direct sunlight, even with a real 200mW laser. You can see the beam in the evening or at the sunset but surely not in direct sunlight
Here is a couple things to try. You should be able to burn black electrical tape, take a wooden match and black marker and mark the match head than you should be able to light it also a you should be able to melt right through a black trash bag. Check the amp draw if you have a DMM. Definitely cannot be seen in direct sunlight.
Nice, thanks guys. Don't know what I'm going to do with it but lately nights here have been kind of misty, should look good in the dark.
A nice greenie is way cool in mist, fog etc. It can be interesting in the rain as well.
With a green laser you don't need fog to see the beam. A dark room is enough or also outdoor after the sunset.
Here's a "beamshot"
From left to right: 10mw Red laser, 10 mw Green laser, 20 mw red laser, 150 mw handmade red laser, 10 mw blue laser.
I take this pic in a foggy evening because red laser are difficult to see but green and blue laser don't need fog...
Now that's a cool pic! The 150mw laser looks like something off of an imperial battle cruiser from star wars.
The 150 mw Laser is the only one that i made by myself using some elettronic component and an old dvd writer.. Is quite impressive. It can also burn black plastic if well focused but i always wear safety goggles when i use it.
i have a 5mW green laser that i can clearly see in a dark room or when it is dark outside. looks like it goes for miles :)
