Q. How long do LED lights last?
A.

ONCE offers a 5 year (24/7) warranty with most products. In poultry and sow facilities you should get 6-7 years. In a sow finishing unit, you may get up to 10 years.

Q. Do you have any trials that validate your performance claims?
A.

Yes, ONCE lighting systems have multiple studies proving weight gain and better feed conversion in agriculture facilities. Visit our Studies Page.

 

When applied to 26,000 birds per house x 6 pounds each x 6 flocks per year = 37,440 pounds more x $0.055 per pound = $2,059 more to producer.   Electricity Cost Savings for Lighting = $426 per house per flock x 6 flocks per year = $2,556 more to producer.  Total value increase to producer per year =$4,615 per house. LED installation Cost (at 75 lights per house) = $2,250.  Payback = 6 months.  Weight .23 better, adjusted feed conversion 3.2 better, livability .36 better, actual feed conversion .005 better.

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. 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. How do I get a lighting layout so I will know how and where to place my new agriculture lights?
A.

ONCE has a designer on staff to make sure you get the correct lighting levels, the correct placement of the lights, and this is cost free. We can help with dimming controllers and surge protection as well.

Q. If I buy your lights, can I get a rebate from my Electrical power provider?
A.

ONCE has a database on providers and rebates that can help you lower the cost of ownership. We also have staff in place to help you if your provider needs technical questions answered and information about product testing to grant you a rebate.  Rebates vary by geography and power provider.

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

Yes, when used with the ONCE® Master or Slave dimming unit you can control the light color and intensity from 5% total red, to 100% bright. Lowering light levels or total dark times helps the swine rest and supports melatonin production.  With the dim to red feature you can let your swine get the rest they need, but still have enough light for staff to see the swine and the environment.

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 in a barn respond to not only the intensity of the lighting in a barn but also the color of the lighting in the barn. For instance with chickens, blue light has a calming affect while red light elicits an excitatory response.

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

Research has shown that animals in a barn respond to the amount of light in the barn. 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.

Q. Why does the color of the light in a barn matter?
A.

Research has shown that animals in a barn respond to not only the intensity of the lighting in a barn but also the color of the lighting in the barn. For instance with chickens, blue light has a calming affect while red light elicits an excitatory response.

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.

Q. Can animals perceive light in their environment without using their eyes?
A.

Many animals can perceive light in their environment with other structures besides their eyes.  These organs can be found in the brain of the animal.

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

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. 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. 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 recent studies (El Halawani 2009, Huber-Eicher et al, 2013) 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 ® LED Lighting Dim-to-Red ® technology is optimized to provided this red spectrum. 

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. 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. ONCE ® offers a 5-year (24/7) warranty.

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.

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. 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. 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. 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. 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. 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.
