New 635nm beam quality is better than old one, New: 2.9x3.8mm diameter,<1.5mrad full angle. Old:5x8mm diameter,<3mrad.
5W RGB(R:1W/635nm, G:2W/532nm, B:2W/445nm) CNI analog modulation diode, DT40pro scanner.
To show the graphic at 10m distance from the laser to wall, it is nice with good white balanced.
It is worthy to pay with low price and high quality.
