Flow-Through In-Grade

The M9800 Series Modular In-grade lights are multi-purpose units designed for flush mounting in soil or concrete. The M9800's are used to uplight large architectural and landscape features. These are the first, modular 400 watt in-grade uplights which provide a new alternative to conventional flood lighting. The units consist of a factory sealed, thermally protected Lamp Module and epoxy encapsulated Power Module placed in a secured Rough-In Section (RIS) which includes channeled convective cooling, an integral junction box, and door assembly. The M9800 has a 460 mm (18 in.) footprint with a cylindrical RIS.
