CMH LEC 315W 3100 K Lamp is a ceramic discharge bulb that offers a full spectrum of white light for indoor cultivation. Compatible with LEC/CMH ballasts, it provides high luminous performance with lower consumption and heat, ideal for cannabis plants.

The CMH LEC 315W 3100 K Lamp is an advanced lighting source that combines energy efficiency, spectral quality, and thermal stability. Its ceramic metal halide (CMH/LEC) technology generates a light spectrum similar to sunlight, favoring both vegetative growth and flowering.
With a color temperature of 3100 K and a CRI above 83, it faithfully reproduces the natural tones of the crop and improves photosynthesis.
Its luminous flux exceeds 37,000 lumens and a PAR PPF value above 510 μmol/s, which guarantees deep light penetration and homogeneous development at all stages.
It is equivalent to a 600 W HPS lamp but with almost half the consumption, significantly reducing heat generation in small spaces.
The CMH LEC 315W 3100 K Lamp uses a PGZX18 socket and must be used with a compatible low-frequency ballast.
Ideal for medium-sized tents, it promotes compact flowers, vigorous plants, and a notable increase in resin production, thanks to the emission of beneficial UV radiation.
At Hydroponics Blanes, a trusted Grow Shop and a reference as a Grow Shop in Spain, it is among the best options for indoor electrical accessories and LED grow light systems that are alternative or combinable with CMH, with discreet shipping and specialized technical support.
The use of a CMH LEC 315W 3100 K Lamp in indoor growing provides an ideal balance between energy efficiency and light quality. Its mixed spectrum allows both growth and flowering without the need to change the bulb. The 3100 K color temperature generates a warm white tone with enough blue component to promote leaf mass and adequate red light to stimulate flowering. Its ability to emit UV-A radiation improves the synthesis of essential oils and terpenes, resulting in more resinous and aromatic flowers. It is perfect for growers seeking a balance between power and controlled temperature in compact spaces.
This lamp functions as the core of the lighting system in grow rooms where thermal stability and professional performance are sought. With a consumption of 315 W, it provides the intensity equivalent to a 600 W HPS system with notable energy savings. Its CMH technology reduces flicker and maintains a stable spectrum even after many hours of use, resulting in uniformity in production. The white light generated allows precise observation of the condition of the leaves, detection of deficiencies or pests, and adjustment of environmental parameters. The PGZX18 socket ensures a secure connection with LEC/CMH reflectors and low-frequency ballasts. It is an essential component within the lighting equipment of any professional or home cannabis grow.
The CMH LEC 315W 3100 K Lamp represents one of the most balanced solutions on the market between consumption, spectrum, and performance. Its competitive price compared to similar power LEDs makes it an excellent option for those seeking professional results with moderate investment. Available at Hydroponics Blanes along with other indoor electrical accessories and complete lighting systems, with discreet shipping throughout Spain.
