AgriShift® Slave Dimmer



• Precise and consistent
• Improves animal welfare
• Schedule up to 500 days divided into 20 periods
• Program timed or temporary dimming override
• Transition time available for daylight simulation
• Optional remote control with standard 0-10V bus
• Fully automatic control or manual options
• Asymmetric program capability
• Incremental dimming

The AgriShift® Slave Dimmer provides smooth dimming of any ONCE® lighting fixture. It is easily controlled either manually with the front panel controls or remotely with a 0-10VDC control signal. The unit is optimized for low light level operation and offers better resolution than other dimmers. Dual output channels allow control of more lights at higher power levels.


Because animals are sensitive to different light intensities and colors of the light spectrum, performance and health can be improved simply by controlling it. Close attention to photoperiods and elimination of lighting anomalies have been shown to increase production outputs, reducing stress and negative effects on animals which enhances overall flock performance.


A Built For Your Barn® design uses techniques and materials that withstand harsh barn environment for years to come.
AgriShift® lighting systems “shift” spectrum and intensity, meeting the individual needs of your animals.


Artificial lighting programs must be applied with a thorough understanding of an animal’s physiological response to light and an incorporation of various characteristics that are sensitive to the way they interact with such lighting programs. ONCE® proprietary SIAM Technology® applies three key aspects we believe best improves animal welfare and optimizes production through artificial lighting for commercial agricultural facilities:

  1. Spectrum: The whole range of visible light with respect to its wavelength or frequency
  2. Irradiance: The power of electromagnetic radiation per unit area (radiative flux) on a surface
  3. Modulation: Transitioning from one lever to another

When using the AgriShift® Master Controller or Slave Dimmer to follow a ONCE® recommended lighting program, you’re providing your animal with smooth dimming and an optimized light spectrum at designated light levels through out the day/production cycle. Not only are you maximizing your overall return on investment, you’ll also experience reduced mortality, improved feed conversion, faster weight gain, reduced stress and other beneficial welfare and productivity enhancements in your animal. Learn more in The Science.
