KEOU‑MB053 is a dual‑zone recessed color ring panel light built for commercial projects where you need a visible upgrade without changing installation habits. The ring and center can run different colors at the same time, controlled via wall‑switch stepping—ideal for retail zoning, hospitality mood areas, and corridors. With an adjustable cutout range of 75–205 mm and a slim 25 mm body, it reduces retrofit risk and simplifies SKU planning. Use the included bid‑ready spec table to confirm size, hole range, and lumens, then request a quote or a sample to validate fit and mode behavior on site.
