What type of lighting fixture is described as a 400 W MH floodlight, ground mounted?

A 400 W metal halide (MH) floodlight that is ground-mounted is classified as a Type "Y" fixture. This classification is often based on the design and intended application of the fixture in providing intense illumination over a wide area, typical for floodlighting purposes. Metal halide fixtures are known for their bright, white light and are commonly used in outdoor settings such as sports fields, parking lots, and outdoor venues, where the goal is to illuminate large areas effectively.

The designation of Type "Y" typically refers to fixtures that are robust, designed for exterior use, and capable of handling high wattages, which aligns perfectly with the specifications of a 400 W MH floodlight. This makes them suitable for tasks that require high-intensity lighting, including security and large-scale outdoor events.

Other types of fixtures might not possess the required durability or lighting efficiency characteristics that a Type "Y" fixture does, which is essential for such applications.
