Ceramic Metal Halide Lamps

Ceramic Metal Halide lamps are the pinnacle generation of HID lighting. Utilizing ceramics materials instead of quartz for the construction of the arch tubes, which contain the metal halide gas that causes the lamps to operate at higher temperatures, increasing efficiency and providing a more complete spectrum, covering the inadequacies standard MH and HPS poses. This makes CMH lamps a better option for horticulture as they efficiently produce more light across the PAR spectrum where it matters most. Grower’s Choice has four different CMH spectrums lamps to customize the light output for every stage of plant growth for optimal harvest potential. For growers using dual lamp models lamp spectrum can be further customized by utilizing different spectrum lamps in the same fixture. We found that 3k + 3K-R provides the best results during the flowering phase, finishing with the 10k lamp in during the last 1 week before harvest.

CMH Benefits over Standard MH:

  • Grower’s Choice CMH lamps are engineered for horticulture specialty crops, provides light output in the full PAR spectrum with greater PPFD per watt.
  • Four lamp options in different PAR spectrums allow the grower to tailor their crops needs specifically from start to finish, increasing yield and quality.
  • More efficient and cooler running CMH means more energy in the form of light reaches your plant vs being lost as heat energy, reducing load on HVAC and service costs.
  • Long service life means low service costs and less material waste.

3K 315W Single Ended CMH Lamp:

Grower’s Choice 3k-CMH lamp utilizes a full phase spectrum that is designed to be used in all stages of growth but optimized for bloom. With a Color Rendering Index of 90 the GC 3k spectrum is very close to natural sunlight but with modest blues, extra red and UV light to serve your plants photosynthetic needs during the flowering phase increasing yields and resin production.

 

Happy Hydro Grow Lamps
TECHNICAL INFORMATION:

Color: 3100K

Type: SE-CMH

Wattage: 315W

Initial Par: 570 umol/s

CRI: 90

Hours: 15,000

  • Contains precision gasses for enhanced spectral output
  • Generates much less heat than HPS and MH
  • More closely matches sunlight than ANY other lighting solution available
  • Growers report tighter inter-nodal spacing and better yields on flowering plants

3K-R 315W Single Ended CMH Lamp:

Growers Choice 3kr-CMH lamp is tailored specifically to enhance bloom production through the discharge of intensified red shift photon dispersion, which plants need to promote heavier yields and additional UV light to facilitate terpine and resin production as this is a plant’s natural response to protect itself from UV radiation.

TECHNICAL INFORMATION:

Color: 3000K

The Grower’s Choice 315w CMH Lamps are suitable for use in all standard 315w CMH fixtures. The 3K-R is an enhanced version of our 3K lamp that is designed specifically for plants that are prized for their resin production. It is similar to the original 3K, but it has contains a few subtle differences.

  • A slight increase in UV light to promote resin production
  • A taller peak in the Far-red to stimulate metabolic activity during flowering
  • Slightly higher PAR for better flower density
  • Increased intensity in red

4K 315W Single Ended CMH Lamp:

Grower’s Choice 4k-CMH Daylight lamp is the best option for hearty vegetative growth leading to a healthy bloom phase. With a Color Rendering Index of 98 and intense full spectrum the Grower’s Choice 4k lamp provides near sunlight photon output. This leads to healthier and more robust vegetative growth.

  • Contains precision gasses for enhanced spectral output
  • Generates much less heat than HPS and MH
  • More closely matches sunlight than ANY other lighting solution available
  • Growers report tighter inter-nodal spacing and better yields on flowering plants

10K 315W MH Finishing Lamp:

Grower’s Choice final phase 10k-CMH finishing lamp should be used during the last week to two weeks before harvest and is specifically designed to emit photons mainly in the ultraviolet 350-425 nm wavelength. As high amounts of UV light cause damage to plant cells, plants compensate in order to protect itself and facilitate reproduction by releasing more resinous oils which translates into a higher quality yield.
