I'll have some pics up tomorrow.
Well for starters, the only other green laser I've had before this was the 75mW phoenix from WL. I realized about a year after I bought it that I had paid to much lol. Anyway I love the price of the 150mW module. $101 shipped is great.
I also love the power. Like I said, I had only had a 75mW green before so double the power was a nice jump lol. With the 150 I can easily light matches at about 6 inches only running the laser off of 2 AA lithiums, putting out about 3.25v.
Visibility is about what you would expect, about 2x as visible as the 75mW. Beam divergence is slightly worse than that of my 75mW but it is still a fairly nice beam. Haven't measured, I will tomorrow, But it's not too bad. The only real complaint I have is that there seems to be a lot of scatter.
I did try out MISTERWILLINGs suggestion in the 7 color build tips thread of using a pot to control power. He was using a 80-100mW module but I figured it'd be pretty much the same. All I had on hand was a 25ohm pot so i tried it out and it was a little touchy toward the end as I expected. I did get all the way from about 1mW all the way up to full power. So for that I just need to get a better suited pot lol.
Other than the scatter I really love the laser and the price. Like I said I'll have pics up tomorrow as soon as I get my day started lol which may be kind of late due to the pain meds I'm on for my surgery
