Considerations when Considering LED
LIGHT SCIENCE Considerations when Considering LED Compared to HID, fluorescent and other light source technologies, LED fixtures are relatively easy to build. Source some reputable LED chips and an electronic driver, provide proper heat-syncing, and one can produce an operational LED light source as easily as building an electric crane […]
Read MoreRed to Far-Red Benefits
LIGHTING SCIENCE Red to Far-Red Benefits from CMH Lamps Back in January, we posted an article about plant response to far-red output. As stated, in the absence of far red radiation, such as when plants are raised under sole-source lighting (e.g. indoor growth chambers), leaves can be under-developed. Therefore, adding […]

Ultraviolet Radiation – Artificial Light Sources Ultraviolet (UV) radiation has long been known to be quite important in biological photochemical reactions. Anthocyanin and other flavinoid pigments absorb blue and UV light to protect chlorophyll from photo-destruction. UV-A, or near UV, is comprised of energy between 315 nm and 400 nm […]
