The latest LEDs from Nichia and other suppliers are game changers. I designed a replacement light source for our Aralab Fitoclima 1200 growth chambers and Nikolai Belevich (Biotechnology Institute) assembled a prototype before the start of the pandemic. This post was written time ago, but I am publishing it now that the final design of the light sources is ready for use after extensive testing. Nikolai Belevich also assembled the six light boxes for three growth chambers based on the final design, to which he also contributed.
In this post I briefly describe the prototype and some of the steps that led to the final design. I also discuss how the latest LED components, icnluding some specifically designed for horticulture, have qualitatively changed lighting possibilities in growth chambers and rooms.
