Grow lighting Lumatek CMH 315 Watt
The Lumatek CMH 315 Watt lighting kit pairs a controllable digital ballast with a ceramic metal halide pulse-start lamp running at 3100K Agro spectrum. Delivering 575 µmol/s PAR output and 32,500 initial lumens at just 334W input power, this full-spectrum fixture covers both vegetative and flowering stages with a single lamp. The six-step dimmable ballast uses square-wave technology for silent, flicker-free operation and is compatible with the Lumatek Digital Control Panel. Lower heat output and a CRI above 90% set CMH apart from conventional HPS. Order now from Plant & Flower.
Lumatek CMH 315W Kit — Full-Spectrum Ceramic Metal Halide Grow Light
The Lumatek CMH 315W kit delivers full-spectrum illumination through ceramic metal halide technology, bridging the gap between traditional HPS fixtures and modern LED systems. Designed for growers seeking superior light quality with lower thermal output, this integrated fixture combines a controllable electronic ballast, a 3100K Agro pulse-start lamp and a compact hammertone reflector.
Performance Specifications
- PAR output: 575 µmol/s at 3100K, providing usable photosynthetic light across the full visible spectrum.
- Luminous efficiency: 104 lm/W with 32,500 initial lumens — up to 20% more efficient than conventional metal halide lamps.
- CRI >90%: near-sunlight spectral quality that supports terpene and essential oil production.
- Ballast input: 334W at 240V, power factor >0.97, efficiency 92%, dimmable from 50% to 100% in six steps using square-wave technology.
Ceramic Arc Tube Technology
The Lumatek 315-930 lamp uses a PCA ceramic arc tube that operates at higher internal temperatures than quartz equivalents. This increases colour rendering, spectral stability and PAR maintenance over the lamp's 12,000-hour rated life. The pulse-start ignition reduces warm-up time and extends restrike capability, while the PGZX18 base ensures a secure twist-lock connection. Unlike conventional HPS lamps that concentrate output in the red-orange band, CMH fills the spectral gaps with blue and green wavelengths critical to healthy photomorphogenesis.
Safety and Control Integration
Full circuit protection covers open/short circuit faults, over-temperature events, voltage fluctuations and end-of-lamp-life detection. EMI suppression is certified. The ballast is compatible with the Lumatek Digital Control Panel for programmable scheduling, simulated sunrise/sunset and automatic dimming when ambient temperature exceeds set parameters.
