Photobio is developed by photobiologists for horticultural professionals!

The mission is quite simple: develop only the best lighting solutions, specific to horticulture, available in the world. The various spectra employed in Photobio fixtures have been trialed extensively to elicit specific photomorphogenic responses in your crop.

Photobio has a unique spectra and optical design. Through our unique spectra we are able to improve nutritional value, extend shelf life, drive more pigmentation, increase active compound production, and shorten flowering times. These spectra have been trialed on over 300 varieties of crops and have been thoroughly fine tuned and proven. Photobio believes that a fixture’s performance should be measured in real world trials rather than by how it looks on paper. Photosynthetically active radiation between 400–700nm (PAR) has been the historical metric used to measure how efficiently the fixture converts power (W) into photosynthetic photon flux (PPF). This is an important measurement but it is eclipsed in importance by plant biologically active radiation between 280–800nm (PBAR). We place more emphasis on PBAR as it incorporates both UV-A/UV-B and far red. Photobio fixtures utilize unique optical design to distribute the superior PPF flux uniformly over your growing area.


  • 1-to-1 LED replacement for 600W HID legacy fixture
  • Optimized optical design delivers 750 μmol/s uniformly to the plant canopy
  • Slim linear design minimizes sun interference when used in a greenhouse environment

Spectrum Information

S4 Spectrum: Provides highly efficient full spectrum with a healthy red-to-blue ratio to drive photosynthesis. Light energy between 500-599nm, previously thought wasted, penetrates deeper into the plant canopy promoting photomorphogenic responses. High color rendering “white” light aids to rapidly identify potential superior working conditions and safety for personnel. Ideal for both flowering and vegetative production.

S1 Spectrum: Developed for businesses heavily focused on flower production for the eventual extraction of pharmaceutical grade concentrates. Provides UV and Far Red outside of the PAR range. UV is responsible for increased terpene content, pest and pathogen resistance, and color expression. Far Red Light is responsible for increased leaf size, which contributes to driving other processes in the plant. More leaf surface area increases photosynthesis which in turn increases flower and fruit biomass.
