Lumatek 315w CDM Ballast Reflector & Choice of Bulbs

The brand new 2018 Lumatek 315w CMH system represents the culmination of many years development & testing.  This ultra reliable, high-output, Lumatek Ceramic Metal Halide ballast & bulb features a high frequency Dimmable Digital Lumatek 315w CMH ballast & High PAR 315w Lumatek 3100k Agro flowering lamp, as well as a free E40 to CMD adapter to convert old HID reflectors.

Lumatek 315w CMH Digital Ballast

The Lumatek 315w CMH Digital Dimmable Ballast is a high output, low power, low-heat digital, dimmable horticultural ballast.


Despite using low-power, & creating low-heat, these powerful little Lumatek CMH ballasts can emit unrivalled PAR per watt figures, even compared to modern digital HPS set-ups. And can provide better gram / watt figures than ever seen before, yet with less energy consumption and at considerably lower grow room temperatures.

Your plants not only get to enjoy far more usable light per watt than ever before, but with lower heat to contend with; your whole grow-room environment is vastly improved. Meaning less stress for grower and plants alike, and no need for clumsy air cooled reflectors, or expensive cooling solutions.


These fantastic high PAR Lumatek CDM systems genuinely can compete with a standard 600w HPS setup, yet with lower running costs, lower temperatures and less stress to your plant canopy. Join the CDM revolution today; at lowest UK and online prices

Also included in this fantastic little Lumatek 315w CMH kit is a CMH reflector. This needs no adapter and will more efficiently run your Lumatek 315w Ceramic Metal Halide system via a bespoke CMH lamp fitting.

Lumatek 315w CMH kits usally come with an adapter for HID reflectors, but these CMH reflectors fit CMH lamps, and therefor provide a more reliable connection between CMH ballast and CMH reflector

Lumatek 315w Ceramic Metal Halide Bulbs

Our Lumatek 315w CMH Ceramic Metal HAlide bulbs, have been engineered for use specifically with Lumatek 315w CMH electronic ballast (included) and is produced using high-grade ceramic arc tube technology and specific horticultural gas blend that creates optimal spectral output for healthy plant growth.

CMH technology creates high energy PAR/PPF levels with low heat at full spectrum which is closer to sunlight and produces healthier plant growth and larger yield. With a CRI (Colour Rendering Index) of >90%, CMH is perfect for growing high quality produce and essential oil extraction. Lumatek 315w Ceramic Metal Halide (also known as CMH/CDM/LEC) lamps are available in 4200K Daylight and 3100K Agro formats.

The PCA ceramic arc tube permits the lamp to operate at higher internal temperatures increasing colour rendering, output and efficiency. PCA resists interaction with the chemicals inside the tube which stabilizes the chemical mix over the life of the lamp, thereby improving colour consistency and PAR/PPF level maintenance. Pulse-start technology enables faster start up & restrike time, longer lamp life and increased lumen maintenance.
