Features and Benefits

HEP plasma light technology is perfect for horticulture grow-lighting:

High output UV spectra: UV from the UV420 is vital for influencing plant physiology to boost nutritional and medicinal value

Tailored Spectral Output: The absence of electrodes enables flexibility in the dose chemistry and spectral output to be accurately specified - perfect for horticulture where UV-B has been overlooked and for tailoring to specific plants or outcomes

Improved Lifetime and Lumen Maintenance: Electrodes and metal-to-glass seals are common failure mechanisms in discharge lighting; with no electrodes, these are eliminated to deliver long life and high lumen maintenance levels of 90%

Very Bright Small Source Size: Single point source improves collection of the generated light for improved energy efficiency.

Good Vertical & Horizontal Illuminance: Point source facilitates efficient reflector designs, distributing light and maintaining high horizontal illuminance, crucial to penetrate through a canopy for uniform growth

Fully Dimmable:  Can be fully controllable, with real–time dimming to 50% of system power and comparable consumption

Rapid Re-start: Power outages are a fact of life, but plasma grow-lights will cool sufficiently to enable a restart within four minutes

'Flicker-Free' Output: HEP lights operate at microwave frequencies and are effectively 'flicker-free' - perfect for video recording.

UV420 plasma grow-lights complement traditional PAR lighting systems:

      Unique Features

  • Delivers UV-B, UV-A and blue wavelengths through 280 to 550nm
  • Working alongside PAR grow-lights for a full sunlight spectrum
  • Small luminaire for excellent light penetration and minimal shadowing
  • Long life of +30,000 hours
  • Prolonged output - maintenance factor of 90%
  • Optimise quantity and wavelengths for a particular growth stage.

      Superior Performance Benefits:

  • In indoor areas, it delivers the UV-B, UV-A and blue missing from most grow-lights
  • Targets key pigments and photoreceptors 'missed' by other growlights
  • Activated photoreceptors produce secondary metabolites eg terpenes, flavonoids, antioxidants
  • Increased chlorophyll production and thereby improved photosynthesis
  • Stronger rooting system to encourage faster vegetative growth
  • Improved pollination from pollinators attracted by the UV on the flowers
  • Reduced microbial attack and pests
  • For growing, adding-value post-harvest; and sterilising between cycles.

      Improved Economics for Higher Returns on Production Activities:

  • Reduces capital costs of replacing units
  • Prolongs light intensity to maximise growth and metabolite production
  • Produces larger crop volumes/weights
  • Enhances medicinal and nutritional values - flavour, colour and potency
  • Reduces cash and environmental costs of hazardous pesticides and fertilisers
  • Increases frequency of crop production
  • In cannabis trials, resin production improved with >20% more CBG, CBD and THC.
