Features and Benefits

HEP Plasma Technology has attributes suitable for supplementary grow lighting:

  • Tailored Spectral Output: The absence of electrodes enables wide flexibility in the dose chemistry and spectral output to be accurately specified.  This means that the ionCORE™ light engine is perfect for horticulture grow-lights and for tailoring to specific plants; our work has also identified opportunities for a UV-C spectrum for sterilisation.
  • Improved Lifetimes and Lumen Maintenance: Electrodes and metal-to-glass seals are the common failure mechanisms in traditional discharge lighting.  With no electrodes in HEP plasma lighting these failure mechanisms are eliminated; this ensures longer life and high lumen maintenance levels of 90%.
  • Very Bright Small Source Size: The small size of the quartz lamp improves collection of the generated light, dramatically improving energy efficiency.
  • Good Vertical & Horizontal Illuminance: The small single point source facilitates efficient reflector designs, distributing light along vertical surfaces whilst maintaining high horizontal illuminance.  This is crucial for horticulture where plasma grow-lights can penetrate through a canopy for uniform plant growth.
  • Fully Dimmable:  HEP plasma lighting can be fully controllable, with real–time dimming down to 50% of system power and with a comparable reduction in power consumption.  This enables fixtures to be utilised very effectively to deliver specific local task lighting requirements as and when required.
  • Rapid Re-start: Power outages are a fact of life, but in such an event, plasma grow-lights will cool sufficiently to enable a full restart within four minutes.
  • Flicker-Free Output: HEP plasma lighting operates at microwave frequencies and is thus effectively flicker-free making it perfect for video recording.

UV420 Plasma Grow-Light is a perfect supplementary grow-light:

      Several Unique Features:

  • Delivers blue-light, UV-A and UV-B and green light through 280 to 550 nm
  • Working alongside 'red-end' spectrum lights, it delivers a fuller natural spectrum
  • Small luminaire for excellent light penetration and minimal shadowing
  • Lamp life in excess of 25,000 hours
  • Output and spectra adjustable to deliver best wavelengths for growing period
  • Quantity and wavelength of light adjusted according to the transmitting filter used.

      Provides Superior Performance Benefits:

  • In indoor areas, it boosts the blue light, UV-A and UV-B required by plants
  • Increased chlorophyll production and thereby improved photosynthesis
  • Triggers blue light photoreceptors, to increase biomass and accelerate growth
  • Stronger rooting system to encourage faster vegetative growth
  • Enhanced colour, fragrance, nutritional value, taste and potency
  • Improved pollination from pollinators attracted by the UV on the flowers
  • Reduced microbial attack and pests.

      Improves Economics for Higher Returns on Investment:

  • Longer life units
  • Prolonged output with ‘Maintenance Factor of +90% over life
  • Fewer HPS units required
  • Lower energy costs
  • Reduced monetary and enviornmental costs of hazardous pesticides
  • Increased frequency of crop production.

      Higher Value End Products:

  • Larger crop volume/weight
  • Improved taste and fragrancy
  • In cannabis, anecdotal evidence shows increased production of cannabinoids - CBD and THC - and resin production by 20%.
