Lumatek 315w CDM Ballast & 3100k Agro Flowering Bulb

The brand new 2018 Lumatek 315w CDM 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 Dimmable 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


The included adapter means you can still use your normal E40 (Screw-in HPS / MH) reflector, all you need – to enjoy fast-growing, high-yielding, potent CMH harvests – but if you need CMH specific reflectors, please see our shop for full kit options.

Lumatek Agro 3100K High Par CMH FLowering Lamp

The Lumatek 31ww CMH pulse-start lamp, has 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.
