Our Technology

The Secret is in Our Technology

As a global leader in agricultural LED lighting applications, we know how important it is to achieve results while improving animal welfare. That is why we focus on applying photo-biology and optogenetics to develop innovative technologies fueled by research.

ONCE® animal-centric lighting systems go beyond traditional LED technologies by studying the science of light specifically and exclusively for the agricultural market. It is the reason we are so successful at what we do, and why our products complement some of the world’s largest integrators and equipment manufacturers.

With over 50 awarded patents and more than 180 patents pending , our proprietary technologies allow us to control all aspects of the environment. Through our research we strive to present species-specific technologies that allow animals to start each day with a sunrise and end each day with a sunset.

Our proprietary SIAM Technology® applies the key aspects that 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
2) Modulation: Transitioning from one lever to another.

Broiler, Pullet and Turkey Jungle Green Technology

ONCE® species-specific lighting systems allow producers to give broilers and pullets a customized lighting solution to achieve what matters most: improved animal welfare, reduced stress and better flock performance. By offering technology developed from decades of proven research, a species-specific spectrum and a Built for Your Barn® design, our broiler, pullet and turkey specific lighting systems are guaranteed to provide a return on your investment.

Experience an ROI after the first flock with our new jungle green light spectrum, providing producers with an estimated$20,508.70 in additional profits per year* and integrators$15,912.00 PER WEEKʠ!

Junglite Green is the newest and most advanced broiler and pullet specific lighting technology on the market today. There are no other products available designed specifically to replicate a birds’ natural habitat with a jungle green light like this technology does. By simulating an enhanced green light spectrum with added blue, a birds’ highest color sensitivity is stimulated, meeting developmental needs at all stages of growth. The added red content regulates circadian rhythms, improving animal welfare. Research has consistently concluded that broilers reared under monochromatic green light during the early stage experienced greater proliferation of the skeletal satellite cells, a primary muscle regenerator, while pullets showed greater weight gain in less time when compared to regular LEDs.

Improve Feed Conversion 

Recent scientific trials showed broilers raised under Junglite Green technology compared to those under a regular blue-enriched white LED showed reduction in bird feed consumption per pound of meat produced. With a .028 feed conversion rate improvement, this provides an ROI after the first flock and is estimated to give producers $19,008.70 in additional profits the first year* and save integrators $15,912.00 PER WEEKʠ! Because ONCE® AgriShift® fixtures have a Built For Your Barn® design, they use techniques and materials that withstand harsh barn environments for years to come, longevity is guaranteed.

*With a savings of .34¢ per pound (lb) and standard gross lbs sold equaling 411,936. ((.34¢ x 411,936 lbs / 2 houses) x 6 houses) x (5 flock turns per year) = Approximate yearly profits – ($3,500.00 Estimated Investment of ONCE® lighting system – $1,500.00 – Estimated investment of other lighting option) = Total profits after investment (i.e. for year 1)

ʠ Assuming a poultry complex places 750,000 birds per week with 96% livability rate, average bird weight is 6.5 pounds (lbs) and Junglite Green™ technology reduces weekly growers’ standards to 0.34¢ per lb. ((750,000 x 96%) x 6.5) x 0.34¢ = Savings per week

**For maximum performance, it is recommended to replace ONCE® fixtures after 50,000 hours or 5 years. 

There was a time when a morning sunrise gave light and an evening sunset gave night to every living creature—it was considered a natural part of life. But not every day is ideal when commercially raising animals indoors.


In the spectrum charts below, daylight at noon, compared to daylight at sunset is compared.


An animals’ natural habitat was meant to be outside—more specifically, the red jungle fowl, an ancestor of the domestic chicken, originated in the rain forests of Southeast Asia. A place where photoperiods are not as drastic and light intensities and spectrum are different when compared to open land areas and many parts of the country. Pecking, nervousness, feed source recognition and hormonal responses may all be seen in chickens outside of their natural habitat, causing increased stress and decreased animal welfare.


The pig, an ancestor of the Eurasian wild boar, also originated in Southeast Asia but on islands such as the Philippines and Indonesia.

Animals See Differently

You can tell simply by looks that a human eye and the eye of an animal are not the same, so it makes sense that we see color differently. When an animal, like a chicken or pig, sees the same light we see, they perceive something different because they have an entirely different set of photoreceptors.

As you can see in the human eye drawing below, the retina at the back of the eye. This is where photoreceptors are located. The two types of photoreceptors that are directly involved with sight are rods and cones. Rods work at low light levels (i.e. night vision), while cones are stimulated by light and used to see color.

Learn more about the human eye.

Two additional key photosensitive in birds, non-visual, organs are the pineal gland, photon absorption by functional photoreceptors located in the pineal gland on the top of the brain, and hypothalamus reception, photon absorption by deep encephalic photoreceptors.

Knowing that cones are used to see color, humans have three pigment cones (trichromatic vision), poultry have four pigment cones (tetrachromatic vision) and swine have two (dichromatism vision).

How Humans See

Lighting for humans is typically categorized on a white scale, but white light, particularly sunlight, is made of all the colors. Think of a glass prism and how it separates white light into all colors.  If the individual colors are mixed differently, the color of the light we perceive changes.

As humans, we all have the same types of photoreceptors in our eyes and will perceive the same colors. The graph below shows the typical color sensitivity of a human. The smooth white line curve and large peak in the center shows that a typical healthy human eye responds to wavelengths between about 400nm to 750nm humans, and sees green and yellow colors better than they see blue and red. The higher the white line is on a color, the more sensitive the human eye is to that color. Looking more closely, you can see the height of the curve in both the red and blue spectrums are much lower than green, which indicates the human eye is not as sensitive to blue light or red light.

How Poultry Sees

The main difference between the way humans see and the way a typical healthly chicken sees is the fourth cone. Instead of being sensitive to three color wavelengths, chickens are sensitive to four. In the graph below, you can see there are 4 (four) distinct color peaks. The highest sensitivity is green, which domestic fowls see similarly to humans. This is so both species can see well in the available light under green forest canopies, a part of our primary natural habitat. Domestic fowls also have a high sensitivity to blue and red, but you can see another one in the UV spectrum (far left bump on the curve).

A bird processes light information differently, meaning they perceive light from ONCE® AgriShift® LED’s 25% brighter than we do. That is why foot candle measurements with a common light meter do not read the red and blue light spectrum. They measure what humans see, not what poultry see.

Because birds see UV, they experience a richer color landscape. The image below demonstrates how a human would see (on the left), the middle image only shows the UV spectrum and the far-right image shows how another bird would see, therefore color matters.


How Swine Sees

In the graph below we see that swine view the world more subdued than humans do. They only see 2 (two) distinct colors, blue and green – with the highest sensitivity being green light. The spectrum drops off significantly before the color red, showing that pigs cannot see that color efficiently.
