Grower's Choice 500W Single Ended CMH Bulb

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.

3K 500W Single Ended CMH:

Color: 3100K
Type: SE-CMH
Wattage: 500W
Initial Par: 840 umol/s
CRI: 90
Hours: 15,000

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.

For use in any standard 500W CMH fixture
Produces more PAR per watt than HPS
Richest spectrum flowering lamp on the market with a CRI of 90
Optimal for flowering but can be used for Veg as well
Promotes higher rate of metabolic activity and resin production through the use of UV and far-red spectra

3K-R 500W Single Ended CMH

Color: 3100K
Type: SE-CMH
Wattage: 500W
Initial Par: 860 umol/s
CRI: 87
Hours: 15,000

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.

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 500W Single Ended CMH

Color: 4200K
Type: SE-CMH
Wattage: 500W
Initial Par: 800 umol/s
CRI: 97
Hours: 15,000

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.

For use in any 500W CMH fixture
Produces more PAR per watt than standard Metal Halide
Richest spectrum on the market
CRI of 97 makes this lamp the closest solution to sunlight available
promotes extremely tight inter-nodal spacing leading to more flowering sites and a fuller canopy
Offers significant improvement in spectral quality over standard Metal Halide
