MegaDrive Linear 400 is California LightWorks’ 400-watt, greenhouse-focused LED fixture designed for supplemental top-lighting with minimal shading. The MDL-400 uses a centralized MegaDrive power unit (no drivers in the fixture) and supports up to 27 fixtures per power drop, reducing in-canopy wiring and heat. It offers two-channel digital spectrum control with 0–100% dimming for daylight balancing and flowering optimization. Manufacturer specifications list 1,044 μmol/s PPF with efficacy up to 3.93 μmol/J, an L90 lifetime over 100,000 hours, and sealed passive cooling for humid environments. The bar measures 30.5 × 3.1 × 5.4 inches (about 77.5 × 7.9 × 13.7 cm) and weighs 10 lb. Typical applications include greenhouses and high-bay indoor rows where the linear form factor minimizes shadowing.
