How to choose laser pointer 1500mw?

At least 200 MW is a good starting point for photographing trees or shooting ranges. But the more intense, the better during the day. Using lasers that can widen or thin the beam for focus adjustment is also a wise choice. The intensity of the beam can be increased by making it thinner or more concentrated. This will make it more visible during the day. For other applications, like demos, you can go for something less powerful, because no doubt you'll be using lasers on a blackboard or whiteboard projection screen, so you can be lighter. No matter where you are directly facing the sun, if you are unsure, it makes more sense to use high power than low power.
