DLI CRI-Series 315W CMH: High-Uniformity Fixture with Flowers-Only Reflector
The Dutch Lighting Innovations CRI-Series 315W CMH is a commercial-grade fixture designed for the highest possible total reflectance at all wavelengths, delivering excellent PAR rendition, efficiency, and uniformity at 1.7 µmol per watt. The unique flowers-only reflector creates a light pattern optimized for canopy-level uniformity — fewer hotspots and more even plant growth across the footprint. Rated at 340W actual power consumption on 120–347V input with a power factor of 0.98 or higher.
Extra Low-Profile CMH Fixture for Low-Ceiling Commercial Grows
The extra low-profile housing makes the CRI-Series ideal for low-ceiling installations where standard fixtures would crowd the vertical space between light and canopy. Plug and play with the DLM-4 Zone Controller via an included RJ12 connection kit for easy installation and on/off control. The improved heatsink increases driver efficiency, an LED indicator provides status and error diagnostics, and the IP65 controller connection keeps the control interface protected in wet environments. Built-in spirit level ensures perfectly even light spread during installation. Dimensions: 16.9" × 11.6" × 7.1", weight: 6.5 kg (14.3 lbs).
Key Features
- 1.7 µmol/W Efficiency: Delivers strong photon output per watt consumed, keeping energy costs competitive across multi-fixture commercial installations
- Flowers-Only Reflector: Proprietary reflector design optimizes light distribution for flowering canopies with fewer hotspots and more uniform PPFD coverage
- Extra Low-Profile Housing: Fits low-ceiling grow rooms where standard fixture heights would limit the vertical distance between light and canopy
- DLM-4 Zone Controller Compatible: Plug and play with the DLI zone controller via included RJ12 connection kit for centralized on/off control across the room
- IP65 Controller Connection: Protected control interface handles wet-environment conditions in greenhouses and humidity-controlled grow rooms
