Cheap and High-Quality 500mW 650nm Red Laser Pointer For Promotion

This model comes with high stability, and the useful life is up to 8000 hours, which means you can keep it for many years under normal circumstances. The visibility of the 650nm laser is relatively low, but you can still see the red beam if the power reaches 500mW. It adopts the copper-nickel alloy housing and multi internal protections. You don't need to worry about overtemperature or overcurrent. This powerful laser pointer can easily ignite matches, and it can work continuously for more than 2 minutes. For better promotion, we offer a wholesale price.

Ultimate heat sinking
It adopts a substantial 40mm copper heatsink surrounded by another aluminum heatsink, maximizing the heat-dissipation-efficiency without active cooling.

Copper-nickel alloy construction
The rest of the laser body is made of copper-nickel alloy, which is very tolerable to scratches and impact damages.

Driver protections
Our electronic driver has several battery protections: over-discharge protection, over-charge protection, and reverse polarity protection.
