The Dimlux 630 Watt Ceramic Metal Halide (CMH) is a professional-grade, full-spectrum horticultural HID lighting system designed to deliver powerful, natural-like illumination for indoor plant cultivation. This complete fixture integrates Dual CMH lamps with an efficient reflector and digital ballast to maximise light output, efficiency, and plant performance in grow rooms or greenhouses.

🔆 High-Intensity Full Spectrum Lighting

  • Includes two 315 W Ceramic Metal Halide (CMH) lamps that produce a broad, balanced light spectrum similar to natural sunlight — beneficial for both vegetative growth and flowering.

  • CMH technology provides excellent color rendering and higher PAR intensity compared with traditional HID lamps, encouraging strong plant development and robust yields.

🌞 Efficient Light Distribution & Reflector Design

  • Built with an Ultra Optics 98 reflector using Miro Silver mirrors and Single Bounce Clear Sight (SBCS) technology to ensure up to 98 % reflective efficiency and excellent light distribution across the canopy.

  • Adjustable side reflectors help increase light overlap and minimise wall reflection losses for more effective canopy coverage.

  • The reflector’s open design allows passive cooling, extending lamp life and maintaining efficiency, with an option to actively extract heat via a 50 mm port.

⚙️ Advanced Control & Performance

  • Features Ultra High Frequency (UHF) digital ballast technology which improves light output and reduces heat generation vs older HID systems.

  • Provides adjustable output levels from around 330 W up to 760 W, giving growers flexibility across different growth stages.

  • Includes Soft Start, Soft-Dim, and Soft-Off functions and offers multiple dimming levels to fine-tune light intensity manually or with a compatible Dimlux Maxi Controller (sold separately).

  • Built-in diagnostic LED indicators and safety protections help ensure reliable operation.

🌱 Grower Advantages

  • Generates very high PAR levels suitable for dense canopies and commercial-scale grows.

  • As both a standalone system or supplementary lighting solution, it offers versatility for various grow setups.

  • The broad spectrum and efficient light delivery support healthier plants, stronger stems, and potentially higher yields compared to non-CMH lighting.
