AgriShift® TLL for Layers and Breeders


The AgriShift® TLL tube light provides poultry producers with an in-system lighting solution that meets the needs of today’s modern poultry houses. Made with Dim-to-Red® technology and a Build For Your Barn® design, the AgriShift® TLL reduces electricity costs, decreases labor and maintenance costs, and increases flock performance.

In-system lighting provides a more uniform and continuous light pattern free of dark spots and shadows. Birds are less likely to be spooked or provoked by movement outside of the system and are noticeably less-stressed and calmer.

The Science Behind the Technology

The AgriShift® TLL has a deep red saturated light output with an added blue and green spectrum, benefiting the vision of your animal. The enhanced red spectrum is the only spectrum which stimulates a hen’s hypothalamic and pineal oscillators, helping maintain circadian rhythms and promoting sexual maturity. It also stimulates the release of two reproduction regulating hormones essential for sexual maturation and daily egg production.

Dim-to-Red® technlogy provides a natural sunrise and sunset simulation, reducing stress on your animals.
