Pulsed Alternating Wavelength System is the key component to XTi technology

Over 12 years of research has shown that the Pulsed Alternating Wavelengths System (PAWS), is the most effective way of delivering light to plants and animals.  PAWS technology takes advantage of proteins present in both plants and animals called chromophores.  Chromophores are proteins that change their shape in response to light energy.  This conformational change results in a subsequent biological change in the plant or animal. 

There are thousands of different chromophores and most of them are "bi-phasic", meaning they exist in two distinct states. One state is when they are in a "ready" state and can accept a light photon of a specific wavelength.  After receiving a light photon, the chromophore undergoes a conformational change and sends off a signal, activates a receptor, opens a ion channel, etc.  At this point the chromophore is in a "refractory" state and can no longer accept the initial photon wavelength.

In order for a chromophore in a refractory state to "reset" to its ready state typically requires a multi-step chemical pathway that takes time.  During this time, the chromophore in its refractory state cannot perform its intended "job".  The second pulse of light in PAWS is a different wavelength and gives the chromophore the energy to immediately return to its "ready" state.  This shortening of the refractory period of the chromophore allows more light initiated information signaling to be driven to the organism.  

These chromophore changes are photo-chemical reactions that happen in the order of femtoseconds.  It is not necessary to deliver light to plants or animals with on off-cycles that mimic the sun (24 hrs).  Instead, these pulsed light signals can be given as a function of ratios of near-red, far-red and blue wavelengths thousands of times per second.  This ability to control signaling is what drives day length and seasonality information to the organism.

Improvements in commercial egg production

Improved economic outcomes for poultry

XTi poultry showed a significant increase in overall production of large, extra large, and jumbo eggs. XTi lighting resulted in increased production, lower mortality, and improved feed conversion.  XTi lit birds represent a significant economic advantage for both commercial and residential egg producers. 

Current demand for eggs is at an all-time high, driven largely in part by the scientific understanding that eggs may not negatively impact cholesterol. In fact, many of the top health advisors in the world consider eggs to be great source of protein and other nutrients. 

In a world rife with supply chain interuptions, labor shortages, rising fuel costs, and bird flu, XTi lighting can be a great way to increase production while decreasing feed and labor costs.   

XTi's patented poultry recipes help producers increase production, decrease mortality, improve feed conversion, and increase profitability.

What difference can XTi lighting make?

Both barns are from a commercial poultry layer facility.  Birds in both barns are the same age and from the same flock.

XTi has been working to improve agricultural welfare and production for over a decade. The video below shows how XTi lighting can have a significant reduction in bird agitation and anxiety.

Dairy Applications


Commercial Dairy Studies

Commercial dairy trials with XTi lighting have shown numerous beneficial outcomes, including:

  • Decreased incidence of dystocia (difficult birthing). 
  • Reduced hypocalcemia (low calcium)
  • Reduced mastitis (inflammation of the udder)
  • Increased milk production 
  • Increased milk fat 
  • Increased rumination 
  • Potential for decreased greenhouse gas emissions and increased sustainability

Horticultural Applications

Benefits of XTi lighting

Fruiting Plants:
