DAYLIGHT 315W CMH WITH SUNSYSTEM LEC REFLECTOR

Description

DAYLIGHT 315W CMH WITH SUNSYSTEM LEC REFLECTOR is the complete ceramic metal halide lighting kit that combines a precision-engineered 315W CMH/LEC fixture with the Sun System LEC reflector, delivering full-spectrum, sun-quality light to the canopy for exceptional vegetative growth and outstanding flowering results. We have been recommending CMH/LEC complete kits to UK growers since 2017 as the premium single-light solution for growers who prioritise spectrum quality alongside energy efficiency.

Why CMH/LEC Technology Represents a Step Change from Conventional HPS

The Ceramic Metal Halide — also known as Light Emitting Ceramic or LEC — arc tube technology operates at higher temperatures and pressures than conventional MH or HPS lamps, producing a plasma discharge with a colour rendering index (CRI) exceeding 90 and a spectral profile that closely mirrors natural sunlight. This broad spectrum includes genuine UV output alongside balanced blue, green, and red wavelengths that drive not just photosynthesis but the full range of plant developmental and biochemical processes that respond to natural solar radiation. Terpene and essential oil production is particularly enhanced by UV exposure — a significant advantage for aromatic crop cultivators. At 315W, CMH technology produces more useful photons per watt than equivalent 315W HPS, making it both more spectrally complete and more energy efficient. The complete kit format with Sun System LEC reflector ensures the lamp is paired with compatible, optimised control gear and reflector optics from day one.

Coverage, Mounting, and Integration into Your Growing System

The 315W CMH with Sun System LEC Reflector is optimised for a 1m x 1m primary canopy, making it ideal for single-light home grows or as a supplemental spectrum enhancer in larger multi-light rooms. Mount at the manufacturer’s recommended height — typically 30–60cm above the canopy — and adjust based on plant response and canopy temperature. The Sun System reflector is designed specifically for the CMH lamp geometry, ensuring even light distribution across the target coverage area. Pair with a quality digital timer or environmental controller for automated photoperiod management. For growers upgrading from standard HPS or looking for the best possible single-light solution for quality-focused cultivation, this complete CMH kit is one of the most compelling options available.
