The Bilberry develops LED lighting technologies for horticultural research and greenhouse applications. The interdisciplinary technical team combines knowledge and experience from optoelectronics, biotechnology fields and IT.  The HORTI series by Bilberry are light fixtures that can provide constant, dimmable light spectrum. Fixtures are equipped with a wireless control module allowing for easy connection with the control software - the Bilberry Plant Research Platform. Optionally, the lighting system can be also equipped with the Bilberry Cable Height Adjustment system.  The variable light spectrum fixture (VSF1) by Bilberry is a light fixture with exchangeable LED panels (light sources) that can dynamically shape light spectrum in the wavelength range from 280 nm (UV) to 855 nm (IR). The user can set and control the light spectrum in order to trigger certain behaviors and metabolic reactions in plants. The fixture is also equipped with a wireless control module allowing for easy connection with the control software of the Bilberry Plant Research Platform. Optionally it can be also equipped with the Bilberry Cable Height Adjustment system.
