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

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.
Ultraviolet Germicidal Irradiation (UVGI) is a subset of light that falls into the entire UVC germicidal range of ultraviolet radiation.
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.
The single most important factor in making any investment is the return. By optimizing photoperiod and intensity, and leveraging light wavelengths that are species-specific, application-specific, beneficial and in some cases ESSENTIAL, a ONCE lighting system can dramatically improve the economics of a facility’s production.
Our luminaires are at least IP66 rated and the materials are specifically chosen and designed to resist harsh barn environments.
Yes, ONCE lighting systems have multiple studies proving improved animal welfare and production in agriculture facilities. Visit our Case Studies page.
ONCE offers an advanced portfolio of lighting systems. To establish compatibility, first look at your power supply (120V or 230V). Then, research local aprobations to undersand what’s needed. Ask your ONCE key account manager or 3rd party sales rep for more information about compatibility in your region.
Our controllers adjust the intensity of our lighting and can receive a 0-10V input signal.
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.
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.
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.
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.

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.
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.
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.
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.
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.
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.
16 of the top 20 egg producers use ONCE LED Lighting Systems.
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..
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.
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.
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.
There is little to no maintenance with the MLS light. The only thing would be to power wash the light on a regular basis.
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.
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.
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.
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.
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.
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.
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.
