Solid State Lighting

We all know we should eat our greens because they’re good for us.

Lithuanian researchers have found a way to make them even healthier by exposing them to short-term light treatment with a solid-state illuminator, reducing harmful nitrate concentration by 44% – 65% and boosting nutritional value.

The researchers grew lettuce, marjoram, and green onions to harvest time in a greenhouse in daylight conditions with supplementary lighting from standard high-pressure sodium lamps. The plants were then given a 3-day treatment with a solid-state illuminator which generates high-density photosynthetic photon flux.
