I know someone already said it but you must know that blue lasers are much more powerful than they look, only 2% of our eyes receptors see blue I have been told as we are most sensitive to green, such as trees, bushes and leaves in the woods.
This is where a lot of us buy our glasses, they are good at a good price. Safety
Feel like I'm in a time warp or something.....lol
Thanks for the welcome guys, this thread is 3 months old tho...lol.
Never recieved my diode, I ordered a 7475 eBay and never recieved it. Filed on PayPal, got my money back and didn't order another one. I did order a couple 520nm 50mw diodes from China a few weeks or so ago, should be getting them soon. Not sure if I'll build a 7475 as the divergence is supposed to be pretty bad. Time will tell,
