    This 300mW RGB Laser Module was tested in house... Red = 110 mW Grn = 51 mW Blu = 117 mW Total = 278mW A little under the advertised 300mW buy close enough for our needs. Unfortunately no hookup instructions included.

    Works perfect with arduino or espressif mcu, can be controlled via PWM and display all colors, definitely worth the buy!

    This RGB White-light laser very well suited to incorporation into laser projectors. The beam is sharp and has a very good combination of the red, green and blue laser beams. The modules are very small and do not seem to get hot in operation. The TTL modulation works well zero to two point five volts keeps the laser held off. Two point five volts to five volts switches the lasers on. I am using Wonsung 20Khz scanners that come with a show card and the output of the show card drives the laser

    Can produce 7 colors (+black/off) depending on the three TTL inputs. Beam quality is fair for the price but no cylindrical correction. The alignment is quite good as well. Even at 10m distance the beams allign quite well. Convergence errors are barely visible with the bare eyes. Nevertheless the beam widens relatively fast ... at 10m it is apx. 8mm in diameter.

    This is very bright. It offers 3 TTL control inputs for Red Green and Blue lasers. I assume that feeding pulse width modulation on these inputs should display most colors like a Tv but have not tried this yet. My only concerns are for safety. What kind of safety glasses do you use? Red Green and Blue at the same time?

    This is a very nice laser module for building small laser show systems. The three colors are alligned quite well. So even in 10m distance they are pretty much on the spot. Divergence is ok. No high end optics is used (still ellyptic shape) but for demonstrations, small shows and experiments. Nevertheless the power of the laser output is quite dangerous. Only people with right eye protection googles and knowledge about hazardous laser radiation should work with such kind of modules. Eye sight can

    Very good RGB Laser, idealy for smaller Rooms, Bars. Good Beam Divergenz, important if you plan to use it into a closed Box to Cool down the Driver Supply and the Laser Diodes. Many thanks for that great Product kindly Regards

    Works well and arrived within a week. Colors mix well but be carefull to give 12V orelse it will get pink if just less than 12V. Haven't tried to use TTL yet but since white is white I expect good results. Spot is not as small as I expected. Consumes about 600mA. Looks very good for the price.

    I have not done extensive testing, but the module works fine out of the box - very bright. I have tested the TTL control, and that works fine too. What more could you expect for this price? Very pleased with the product and shipping.
