315w 4200K Ceramic Metal Halide - CMH Grow Lamp - PGZ18 style base

315w 4200K Ceramic Metal Halide - CMH Grow Lamp - PGZ18 style base

CMH Grow lamps deliver a high PAR output and a broad, sun like spectrum, making them a favourite for both vegetative and flowering stages

  • CMH Offers Superior Colour Temperature 4200k – Ideal and highly effective for vegetative growth
  • High Luminosity – Emits an impressive 33,000 initial lumens, ensuring intense illumination for photosynthetic efficiency
  • CRI 95- Colour Rendering Index, measures how accurately a light source displays colours compared to a reference light source. CRI can be useful for human visibility in grow environments, but it is not a key factor in determining a grow light’s effectiveness for photosynthesis
  • CMH lamps offer a very High Ultraviolet UVA and UVB output
  • European PCA - Polycrystalline Alumina, a translucent ceramic material used in the lamp arc tube. Its unique properties make it ideal for HID lighting, with High thermal resistance withstanding temperatures exceeding 1,600°C. Its translucency allows for efficient emission of visible light while containing the arc discharge with improved colour consistency and efficiency stabilising the lamps spectral output over time, enhancing both performance and longevity
  • Energy efficient, high PAR value lamp spectrum, delivers a Photosynthetically Active Radiation (PAR) output of 630 µmol/s this is a high PAR per watt ratio, outperforming traditional HID lamps in terms of usable light spectrum and efficiency
  • Reduced operating temperature, CMH lamps operate at lower temperatures compared to traditional HPS or Metal Halide lamps. With less heat stress on plants, allowing you to position the light closer to the canopy without the risk of burning. Lower cooling requirements, which reduce energy costs and simplify ventilation requirements 
  • Made for Advanced low frequency square wave technology with its stable power delivery – Low frequency square wave ballasts provide a more consistent and smoother electrical current to the lamp, reducing flicker and improving lamp longevity.
  • Rated life span 20000 hours
  • Suits PGZ18 lamp sockets
