What XtremeLUX offers for R&D:

Since 2011 XtremeLUX has been providing lighting products for plant research, and the range of capabilities and applicabilities have grown ever since.

Variety of systems
  • IP68 remote-driver light bars capable of operation under water
  • Analog-controlled dimming ranges up to 10,000:1 without flicker
  • Dimming response times down to 4 milliseconds
  • Directional sources with adjustable beam angle
  • PPFD up to 15,000 µmol/m2/s (7 suns)
  • Light bars with beam angles from 16° to 150° full-width- half-maximum
  • Factory-calibrated light bars with thermal compensation and linearized 1000:1 dimming ranges for high accuracy and repeatability
  • Narrowband and broadband spectra from UVB to far red
  • Phosphorescence-free light bars for extreme on/off photon flux ratios

Variety of applications
  • High-power light bars are in use at U.C. Davis for stimulating Arabidopsis plants that subsequently glow due to transplanted firefly genes. Low phosphorescence enables cameras to pick up the dim glow from the plants.
  • High-power directive sources simulate the sunrise-to-sunset angular trajectory of sunlight for studies involving the daily motions of sunflowers.
  • Light bars used at Google to study effects of spectrum, photon fluence rates, and other variables on leafy green plant morphologies and yields.
  • Studies are being conducted in cannabis trial rooms to assess the effects that spectrum, fluence rates, angular distributions, intensity-vs-time profiles, and other variables, have on yields, product quality, plant morphology, insect and pathogen resistance, etc.
