Can you see the beam from the Dealextreme 200 mW red laser? A lot of people have asked me this and in this video I'll try to show you the answer.
It highly depends on the conditions. It's never as bright as even a low power (20-30 mW) green laser but this is because of the human eye. Our eyes are not very sensitive to red light compared to green light so if you are looking for maximum beam visibility in clear air you should always go for a green laser.
Hope this video clarifies even though it's hard to show you how it looks in real life. In real life it looks way better with its intense red color.

Captions in case you don't understand every word of my danish accent:
Hi. A lot of people have asked me: Can you see the beam from the 200 mW red laser from Dealextreme?
The answer is: Well... sort of... It depends on the circumstances. Let me clarify.
On their website they claim it to be visible in daylight. But it isn't. Just watch my first video. You can't see the beam in daylight.
So what about in less powerful artificial light? Well... No... Not really.
Okay. What about without light? Yes, you can see it but it's faint.
Now let's try it with smoke in the air. Just a little puff from a very cheap smoke machine.
I think the pictures spoke for themselves. There even was a reflection in the cabinet doors.
Now I'll just leave you with a bonus clip. See ya later
