Cree is a US-based LED manufacturer. It is well-regarded for its high-quality products and innovation in lighting. Color temperature is a characteristic of light. It is used to quantify the color appearance of light sources. Flashlights use the smooth reflector when long-range light is important. This includes searchlights and thrower flashlights. The AR coating on the lens maximizes light transmission. This makes the flashlight more effective in darker environments.

The Javelot Pro uses multiple switches. The switches' placement and design determine this. They allow for one-handed operation. The flashlight has electronic switches. They have many benefits and extra features compared to mechanical switches. A simple press or click of the rear switch turns the flashlight on or off. This removes the need for complex button combinations or multi-step processes.
