Difference between 1mW and 5mW lasers or advantages

Q: What is the difference between 1mW and 5mW move shoot move lasers or advantages?

MSM: The main difference between the 1mW and 5mW move shoot move lasers is their output power, as you could see from their names.

So the advantage of the 5mW version is: its beam is stronger than the 1mW version’s. It could be used in the light pollution area.

The advantage of the 1mW is: it is more power-effective than the 5mW version. So it could be used for a longer time than the 5mW version. Moreover, it could be used in a sub 0°Celsius environment.
