Agricultural Lighting

ONCE® animal-centric lighting systems go beyond traditional LEDs by offering a SOLUTION designed to simultaneously improve production and animal welfare.


We research the science of light exclusively for the agricultural market and incorporate the findings into commercial patented technologies.


At ONCE®, we base our technology on decades of proven research so both the animals and your bottom line benefit, leaving you to feel confident with your informed decision.


By incorporating photo-biology into innovative technologies, ONCE® can minimize sudden changes in light and provide natural daylight simulation, reducing animal stress and improving welfare.


Every single day begins with a sunrise and ends with a sunset, but not every day is ideal.

It can be for your animals.
