It's a rare event when one technological breakthrough can have far-reaching effects in fields as diverse as stage lighting, horticulture, entomology, energy management, and potentially, space colonization. Penn State researchers from theatre arts and horticulture have collaborated with the Office of Physical Plant to fine-tune lighting for improved plant growth and energy conservation in greenhouses.

Light-emitting diodes (LEDs) have been used for years because of their energy-efficient properties and theatre arts professionals are well aware of the lighting sources' ability to enhance drama on stage. But now a research grant, secured in 2010, is helping to show how the same lights can have a multi-pronged benefit in greenhouses.
