Product Overview

The MaxLite RADM-18WCSTA Recessed Architectural Downlight Light Engine is a versatile, high-performance modular lighting solution designed to upgrade legacy incandescent, fluorescent, or metal halide downlights in commercial and architectural spaces. Featuring 3 selectable wattages (18W, 24W, 30W) and 5 selectable color temperatures (2700K, 3000K, 3500K, 4000K, 5000K), this TAA-compliant light engine provides up to 2,800 lumens of high-efficiency illumination. Equipped with multi-mode dimming (TRIAC/ELV at 120V and 0-10V at 120-277V), an adjustable beam angle from 25° to 45°, and a 12V auxiliary output for MaxLite c-Max control nodes, it delivers future-proof adaptability for both retrofit and new construction projects.

Key Features & Benefits
