Q. Do you have any comments from growers that use your lights?
A.
“I changed my lights to ONCE® and I am seeing a $500.00 a  month power savings on my 4 house farm. I love the lights.”
 
“I love these lights, my weight has improved and I don’t change lights out anymore.”
 
“I finished first for the first time. The only change I made was installing the ONCE® lights. These lights are great.”
 
“I had cold cathodes in my broiler houses and my performance began to slip over time. I put the ONCE® lights in and my performance came back and my lights are not failing.”
 
“I have a 8 house farm and installed 2 houses of cheap LED’s. I was not satisfied with the light in these houses. I put the ONCE® LED’s in my other 6 houses and my lighting is much better. My weights are heavier in the ONCE® houses.”

 

Q. How much money will I save using your LED's in my Broiler House?
A.

A typical poultry house has 50 house light and 20 brood lights, By replacing your 60-100 watt incandescent lights you will save $120.00 to $150.00 per house per month. Your energy savings will pay for your LED’s within one year or less. ONCE® LED’s are an Agriculture LED designed for how poultry perceive light and not humans. Data have showed that using ONCE® LED’s will improve poultry performance. Improved performance will also help pay for your ONCE® LED’s. ONCE® LED’s are the only item you can install in your poultry operations that will pay for themselves.

Q. Why does the ONCE® LED broiler light have a red and a blue light output?
A.

ONCE ® LED lights are designed for how the poultry visualize light. ONCE ® LED lights produce the correct light spectrum so the birds can maximize their growth potential. This is why color matters. By having the red spectrum during brooding ONCE ® lights promote early growth. Then during the grow-out as you dim your lights ONCE ® LED lights shift color to a blue light spectrum. This blue light spectrum keeps your birds calmer which improves your feed conversion. Other LED lights are designed for how people see light and do not have the full color spectrum needed to maximize bird performance.

Q. With the ONCE® lighting system, will there be shadows and dark spots in the poultry house?
A.

ONCE LED’s are designed to provide 180 degrees of light coverage in the poultry house. This eliminates shadows or dark areas in the poultry house.  The wide coverage minimizes the ring of light effect you get with some household LED bulbs.  The uniform lighting also encourages uniform bird growth.

Q. Are dimmers necessary for the layer barn?
A.

Dimmers are necessary to properly manage the intensity of the light in the barn. With the availability of dimming and LED light sources, you are better able to monitor the light level and influence the behavior of the birds. By dimming to the proper light level, you can calm a skittish flock of layers. With the use of a programmable dimmer, you are also able to simulate a sunrise and sunset effect when transitioning which reduces stress on the birds.

Q. What is the significance of red light for layers?
A.

Red light has a significant impact on egg-laying performance and much research has been done on which type of red light is most beneficial. Two different studies show that red light (630 nanometers wavelength) is the most beneficial to laying hens; this particular color is “superior to any other wavelength in increasing egg production” (El Halawani, 2009). ONCE® lighting systems use proprietary Dim-to-Red® Technology, which is optimized to provided this red spectrum.

Q. What makes ONCE® different from other agriculture LED light bulbs?
A.

ONCE is an innovative photo-biology company who designs and manufactures animal-centric lighting systems. Meaning, we do not just sell “LED light bulbs”. Because animals perceive light differently than we do, all of our systems are species-specific, have both the animal and farmer in mind, and are designed to influence desirable biological processes to achieve optimum results. Most of our products are Built For Your Barn and have a 5 year (24/7) warranty.

Q. What type of lighting do you use for Pullets?
A.

ONCE ® has developed a Dim-to-Blue ® Pullet Light that optimizes the color spectrum to mimic the Autumn photoperiod. Studies have shown higher body weight gains and reduced feather pecking injuries by using this system.

Q. Who is currently using ONCE® lights in their Layer barns?
A.

16 of the top 20 egg producers use ONCE  LED Lighting Systems.

Q. Why should I buy ONCE lighting systems for my layer facilities?
A.

The single most important factor in making any investment is the return. By basing our technologies on decades of proven research, we have had the opportunity to work closely with researchers, in addition to the primary breeders, equipment manufactures and producers throughout the years. This has allowed us to not only develop a lighting system, but also a technology that provides optimal illumination to exceed the needs of the industry.

Q. What type of lighting is recommended for Pullets?
A.

We recommend a blue/green light spectrum when raising Layer Pullets. Our research has concluded that the green light spectrum has been shown to enhance growth in poultry during their early stage by enhancing proliferation of skeletal muscle satellite cells. It encourages uniformity in growth. Growing under this spectrum allow uniformity in your hen size and prevents them from going into lay too early. Learn more about pullet lighting

Q. From a biological perspective, what is the importance of the red spectrum?
A.

One of the main functions of red light is Melatonin regulation and stimulation of reproductive activity. The red spectrum is the only spectrum which entrains hypothalamic (the reproductive controller in a hen) and pineal oscillators. The rhythm of melatonin synthesis is driven both by an extrapineal and an intrapineal oscillator entrained by light and dark information, which is perceived directly and indirectly by the pineal gland. Melatonin enhances the immune response and counteracts immunodeficiency states resulting from acute stress, viral diseases, aging, or drug treatment. With this knowledge, artificial lighting programs with the red spectrum can be a useful tool to direct desirable behaviors in poultry. When used properly, red light can have a significant impact on egg-laying performance. Layers under ONCE Dim-to-Red technology are calmer, less prone to flight and notably less aggressive.

Q. How are dimmers used in layer facilities?
A.

Dimmers have several functions. The first function is to simulate natural sunrise / sunset, which triggers the circadian cycle in poultry. The secondary function of a dimmer is to manage the birds and move them through out a cage-free system. By having a higher intensity light under the system, we are able to minimize floor eggs. In addition, by using different intensity levels, we can move the birds back into the system at night and into the areas that we want them to go. During the day, we’re able to move them both horizontally and vertically through out the system by using different dimming intensity levels. Finally, by strategically locating the lights in the system, we’re able to reduce checked eggs. Shop our AgriShift Dim.

Q. How do animals see?
A.

Most animals see with their eyes. What an animal sees depends on the structures within their eyes. These structures are not only responsible for visual imaging but also the colors perceived in the environment. The light we see affects our mind and a wide variety of metabolic processes within our body. Learn more about the visible light spectrum and how animals see differently in The Science..

Q. How does barn lighting affect animal productivity?
A.

Research has shown that animals grow better when they have optimum lighting conditions. Barn lighting can create an environment that enhances feed conversion, reduces stress on the animal and promotes growth. Read How Poultry See for more information.

Most Commonly Asked
Q. How long will a ONCE® LED Swine light last?
A.

In a Sow unit you should get 6 – 7 years. In a finishing unit, you may get up to 10 years. LED lights do not burn out like other traditional lighting bulbs or lamps and eliminates constant bulb changes which saves time and money. The LED light intensity output decreases over time. Inferior household LED bulbs may go prematurely dim in as little as a year especially when mounted in a glass jelly jar fixture. Shop Swine lighting.

Q. How much energy will I save using ONCE® LED lights?
A.

ONCE LED Lights use only 8-17 watts of electricity (1/3rd to 1/30th of Incandescent or CFL). This will save money on electricity and replacement costs because ONCE ® LED lights last 5-10 years.

Q. Is the ONCE® MLS Swine Light Easy to maintain?
A.

There is little to no maintenance with the MLS light. The only thing would be to power wash the light on a regular basis.

Q. Why is lighting important in swine barns?
A.

 Lighting plays a significant role in reproductive and overall swine production performance. Each level of production requires different light levels and photoperiods. The amount and type of environmental light swine receive directly affects hormonal cycles and can contribute to animal well-being or increase physiological stress. With artificial lighting, the correct design of a lighting system in a swine barn is critical to maximize light efficiency, minimize overlift or underlit areas and promote healthy development and growth.

Most Commonly Asked
Q. Besides photoperiod control, what else should I consider in a lighting system?
A.

A fish’s response to light is complex, and will depend on the degree of light stimulation that it receives, as well as the unique light receptors the fish has at a particular stage of development. The degree of light stimulation received will depend on the light system used (intensity and spectrum), the photoperiod and water absorbance properties. An artificial lighting system must be designed for a fish’s particular natural ecology, photosensitive structures at a developmental stage, and its present artificial culture environment.

Q. How can choosing the correct light in the fish’s environment, improve production?
A.

Light has been shown to be a useful tool in manipulating a fish’s maturation rate and feed intake. This has, in turn, allowed farmers to realize higher value on their sold product, and to reduce feed costs and improve feed conversion. Light in an animal’s environment can support a better immune response to disease agents, reduce aggressive behavior and directly affect the cosmetic presentation of the product in the marketplace. Indirectly, the lighting in a facility can improve water quality and therefore reduce water remediation efforts.

Q. How do fish perceive the light in their environment?
A.

The ability to perceive light in their environment changes as a fish develops. Although vision seems to be the primary sense involved in foraging activity and feeding for most fish, non-retinal photoreceptors, such as the pineal organ and deep brain photoreceptors, play key roles in a fish’s physiological response to light. In some fish species, these non-retinal photoreceptors are functional as early as one day post-fertilization, long before the eyes have developed in the embryonic fish.

Q. What is circadian rhythm?
A.

The circadian rhythm is the result of the fish’s internal clock. It regulates the body’s chemical and hormonal production and metabolism along an approximately 24-hour cycle. Circadian rhythms are generated by the body, but external stimuli can affect them. Light is one of the biggest cues for the circadian rhythm.

Q. What is the advantage of using LED lighting systems in an aquaculture facility?
A.

An LED lighting system will be substantially lower in cost to operate than any other traditional lighting system. Usually an LED system is 1/10th the cost to operate. Although upfront costs may be significantly high, they are offset by the considerable energy savings and long life. A typical LED lighting system is guaranteed for 3-5 years and high-quality units designed for aquaculture environments will last considerably longer. LED systems can have a varied spectral outputs and dimming capabilities in a single lamp, so that the lighting system can be fully adapted to the lighting needs of that particular fish under culture–something not capable by other traditional lighting technologies.  In addition, due to their ruggedness and efficient size, LED lighting systems can be placed anywhere in the aquaculture environment; above the tank or even submersed in the tank.

Q. Why is lighting important in a fish hatchery?
A.

Light in a fish’s environment is a key factor that synchronizes all life-stages of fish, from embryo development to sexual development. There are daily and annual changes in natural light. Over thousands of years of evolution, fish species have adapted to these predictable changes in light by developing a circadian system or biological clock that entrains rhythmic physiology and behavior.

Q. Can we put any metal or liquid object inside the box?
A.

Flammable liquids should not be placed inside BioShift®. Metals and other hard surface objects are okay.

Q. Do you have efficacy reports showing before and after contamination loads?
A.

Yes, we tested efficacy through a third party laboratory, testing two common viruses. They found that 5 minutes of exposure resulted in a 4-log reduction of viable viruses. ‘

The PRRS and PED virus stocks were diluted 10-fold and assayed for infectivity and/or cytotoxicity in their respective host cell lines. Based on these control results, the TCID50/100 uL for the PRRSV input was determined to be 105.00. The TCID50/100 uL for the PEDV input was determined to be 105.00

Q. How safe is it to put food inside the BioShift?
A.
If the food is contained in a bag or container, no UV radiation will actually hit the food. If the food is directly exposed to UV light, the food remains safe to eat. In fact, UV irradiation is commonly used in the food industry to disinfect food prior to packaging. See the info from FDA below: 

https://www.fda.gov/Food/IngredientsPackagingLabeling/IrradiatedFoodPackaging/ucm081050.htm

Q. What germs, pathogens or viruses are not effective using UVC?
A.

Different viruses and bacteria have different susceptibilities to UVC, which is dependent on the presence of DNA repair enzymes. In the below reference, several different bacteria showed different sensitivities to UVC. In that paper, most bacteria were reduced by 90% with a fluence of 3-4 mW*s*cm^-2 UVC radiation. Five minutes exposure in the BioShift® results in 54-84 mW*s*cm^-2 UVC radiation. One notable UVC-resistant bacterium is called Deinococcus radiodurans, which requires ~91 mW*s*cm^-2 UVC radiation. It, however, is not a pathogen.

Q. What is the frequency of the UV light?
A.

The germicidal UVC bulbs use excited mercury vapor, which emits primarily at 254 nm (and a small amount of visible light >400nm). This light is not safe to expose to your skin or eyes directly.

Q. What is Ultraviolet Germicidal Irradiation (UVGI)?
A.

Ultraviolet Germicidal Irradiation (UVGI) is a subset of light that falls into the entire UVC germicidal range of ultraviolet radiation.

Q. What UVC lighting options are available?
A.

Several artificial sources of UVC exist, most being fluorescent mercury lamps with peak emission at 254 nm (optimal killing is 265 nm). A majority of the UVC LEDs being developed emit the optimal 265 nm, are more energy-efficient, require no warm-up time, and have longer lifespans.

Q. Can ONCE lighting be connected to farm controllers?
A.

Our controllers adjust the intensity of our lighting and can receive a 0-10V input signal.

Choosing The Right Lighting For Your Barn
Q. Why does the color of the light in a barn matter?
A.

Research has shown that animals not only respond to the intensity of light, but also the color. The spectral characteristics of a sprectrum, as well as the intensity, affect how light is perceived. As animal production has moved indoors, many wavelengths of the natural light spectrum are lost. Some of these wavelengths can have a beneficial affect on metrics and animal welfare. Learn more about how animals see light differently.

Q. Can the lights be dimmed? Is this a good idea?
A.

Absoutely, yes! An optimized lighting schedule includes manipulation of light intensity. Dimming is an essential function of ANY lighting system or solution in indoor animal rearing.

The Science
Q. How does barn lighting affect animals?
A.

Research has shown that a lighting environment plays a very significant role in the production metrics of animals raised indoors. Making a well-informed decision to invest in a lighting system can dramatically improve production metrics AND animal welfare—two factors that are highly dependent on each other.

Q. Why does the intensity of the lighting in a barn make a difference?
A.

In any animal schedule (or light recipe), light intensity is important. This can be dependent on the time of day (setting the photoperiod), or on the stage of life an animal is at. If the light is too bright in intensity, the animal will be stressed. However, if the light is too low, the animal will not develop correctly. The objective of artificial lighting should be to provide the animal with the optimum lighting so that it prospers and grows.
