Did some research re 445 + 450. It seems they are two different products... and I'm not 100% sure but I think the 450 is single mode, generally lower power. Would love to know then why laserbtb marked my 445 as a 450 lol
Thanks for the rep man, helps me a lot! Back at you, i think you are a nice guy! Think you got a little too much crap on that last thread. Keep up the experimenting!
