CMH 315 Fixture & Bulb

R5 500 - R5 500


Ceramic Metal Halide or CMH for short (some refer to it as CDM), is becoming more popular in the horticultural industry. The CMH lamps have a very broad light spectrum which is more similar to the sun itself than any other form of HID lamp. We have taken CMH technology and increased its operational efficiency, making the most comprehensive spectrum of light output for an HID fixture even better. The CMH lamps also have increased efficiency in PAR/Watt compared to other forms of HID lighting. The CMH fixture can be used as a primary veg light, a primary light for SOG applications, or a supplemental full spectrum light for large flowering operations.

Fully sealed, low frequency ballast is side mounted. The CMH 315 single lamp fixtures vertical lamp mounting position provides an even light footprint. Meets ETL Standards and uses 97% German reflective material. Both Nanolux CMH fixtures can be used with any 315W 3K or 4K horticultural lamp from all the leading quality brands.


CMH 3K/4K Bulb included

CERMIC METAL HALIDE LAMP 315W 3K & 4K MaxPar CMH lamps are broad spectrum “white” light lamps. MH lamps are predominantly blue spectrum focused and HPS lamps are predominantly red/yellow focused. CMH lamp technology is broad-spectrum based. A CMH lamp has 2.5 times the blue light of an HPS lamp. The 13.4% blue light from CMH lamps is slightly higher than a 50/50 mix of HPS and MH lamps. A CMH lamp has a far more uniform spectral output than any other lamp used in horticultural lighting. MaxPar offers color temperatures in both 3K (3100K) and 4K (4200K) models. CMH lamps are suitable for cloning, flowering, and vegetative growth. MaxPar CMH lamps should be considered a valuable component in any lighting setup.
