4. some people may think orange is exactly the same with the color of orange. it is incorrect. compare with 638nm and 660nm, 638nm is brighter when they are in the same output. 638nm is closer with the yellow color so that we call it orange/red. it cannot be exactly the color like a orange or sun.
The modules are tested and the output power are measured by laser power meter before sending out.
Please don't compare the power of this one with a none-measured laser.
If you doubt the output, please have the laser you recieved checked by laser power meter.
