The PLTB450B 1.6W diode has a better beam profile than the M140. Using a G2 with the PLTB450B still gives a great tight beam profile.G2 laser lens will be good if i want thinn laser beam ?
I have 3 of them myself.
Can you use 2 "18350"s" or 2 "16340's"? Then you can run the first driver you showed.
Using 1 "18650" you will need a boost driver I believe and maby only get 1.2A with it.. I'm not experienced enough on this so maby others will chime in..
Could be the driver you showed will work well with 1 cell. I'm really behind the times..
I think Laserland is a decent place but its located in China so shipping might be slower a little slower.
Yes they have a 95% feedback score but it only takes 2 negative feedbacks to drop them there if they only show 132 items sold in the last month..
