1 LED Lighting Update and Field Experiences By Jon Moyle

2 Lighting Brooding Growing

3 Lighting Light needs to be provided at the appropriate brightness Measure light level at feed lines in between the light bulbs Measure here

4 Grower Survey (Delmarva) What is your main type of lighting? Percent Incandescent 54.84% Cold Cathode 25.81% Compact Florescent 8.87% LED 10.48%

5 Grower Survey (Delmarva) What type of brood lighting? Percent Incandescent 37.80% Cold Cathode 3.15% Compact Florescent 48.03% LED 5.51%

6 Incandescent

7 Compact Florescent

8 Cold Cathode (CCFL)

9 LED Lamps

10 Organic LED

11 Comparing Bulbs Type Power (W) Initial Light Output (Lumens) Lumens/ Watt Average Life (hours) Incandescent ,000 CFL* ,000 CCFL* ,000 LED ,000 *Contain mercury

12 Heat is the Enemy Heat reduces the life of the bulb/lamp Some have fins to help disperse heat Need to be cleaned Lower energy use means lower heat output More efficient lighting produces less heat energy and more light energy

13 So why LED Adaptable Use less electivity Save money Long life Lower light depreciation Only lose ~5% per year Incentives Cost share Reduced cost of lamps (some dimmable 6 watts with 5 year warranty are <$12)

14 LED Style

15 Style

16 LED Non traditional lighting

17 Color (Kelvin K) Most lighting sold based on color Kelvins (K) used to represent lamp color Compresses spectrum to one number But spectrum is rarely one color

20 Yellow vs. White 3,200 5,600

21 Is Color important? Broilers In a study looking at light color, chickens occupied both colors evenly and did not show a preference Mendes et al., J. Appl. Poult. Res. 22 :62 70

22 Is Color important? Layers LEDs can be used to produce monochromatic light at specific wavelengths (color) Green light increase foraging and exploring Red light reduced aggression and accelerated sexual development Huber-Eicher et al. Poultry Science 92 :

23 Hatchery? Hatchery Broilers - results indicate that LED light stimulation of chickens during embryogenesis results in increased hatchability, improved chick quality, and had long-term effects on fear responses and stress susceptibility; furthermore, they indicate that warm versus cool light was not a factor. * Layers-increased quality of chicks *The effect of exposing chicken embryos to warm- or cool-spectrum light-emitting diode (LED) light during incubation on hatchability, embryo mortality, 14-d growth and FCR, fear and physical asymmetry.

24 SO WHAT'S IN IT FOR GROWERS

25 Electrical Use 2008 Side Wall Ventilation 4% Miscellaneous 2% Lighting 32% Tunnel Ventilation 62%

26 Electrical Use 2014 Other Motors and Pumps 7% Miscellaneous 2% Poultry House Lighting 6% General Lighting 5% Ventilation 80%

27 Production Results Farm #1 Light Type Body Wt. Feed Conversation Livability LED % Incandescent % *Four flocks

28 Production Results Farm #2 Light Type Body Wt. Feed Conversation Livability LED Incandescent *8 Watt LED vs 60 Watt Incandescence Through 5 flocks

29 Production Results 7 Bird Weight Flock 1 Flock 2 Flock 3 Flock 4 Flock 5 LED Incandescent

30 Production Results 2.5 Feed Conversion Flock 1 Flock 2 Flock 3 Flock 4 Flock 5 LED Incandescent

31 Production Results 120 Livability Flock 1 Flock 2 Flock 3 Flock 4 Flock 5 LED Incandescent

32 Economic Payback Separate meters on Light circuits Installed 96-8 watt A-19 LED verses 60 watt incandesces Grower paying $.12 per KwH Results No bird performance loss ( paired chicks) 93-95% energy savings $1700 per house $17.70 savings per bulb Bulb Retails for $16 11 month payback

33 Grower Survey (Delmarva) How likely are you to change to LED lighting? Percent Yes 40.14% Maybe 41.55% No 5.63% Use LED lighting now 5.63%

34 Dimmers Dimmers fall into two categories Resistance: Alters voltage Electronic (Triac): Alters current wave Altering voltage Incandescent output proportional to voltage Decrease voltage, decrease light Decreased voltage, increased life Incandescent lamps dim to ~0%

35 Dimmers What about LED? Do not work well with varied voltage Some lamps are designed for use with dimmers Requires revised ballast design to reduce power to bulb New specific dimmer designs available Not all lamps turn on or turn off at the same dimmer setting

36 A Couple of Interesting Findings Do you use ? Yes 75.37% No 24.63% Do you use the Extension websites for educational information? Yes 56.74% No 43.26%

37 Conclusion LED lighting can save growers money on electric bills Less than a one year pay back (can be free with incentives) LED lighting does not hurt production Weight Feed conversion Mortality
