Rubol’s MCP 12 is a 200 W DIY LED grow-light kit built around Multi C.O.B. Panels. The fixture uses 12 COB modules; each COB contains 144 individual diodes for a total of 1,728, supporting efficient light output across the panel. Standard builds ship with a warm, full-spectrum 3500 K white, and the COBs can be configured between roughly 2700–4000 K to emphasize growth or flowering. Beam control is available via optional 60°, 90° or 120° lenses and reflectors, so usable coverage depends on the chosen optics and mounting height. In practice, two MCP 12 units have been run as a 400 W indoor setup. The model appears in vendor listings dated May 20, 2019, and links to Rubol for further technical details.
