Agricultural Lighting

ONCE® is a Signify brand. Together we lead the world with highly innovative dynamic lighting solutions that unlock the potential of light.


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.
