1 Field Demonstration of Advanced Lighting Technologies for Poultry Houses Susan Watkins, Susan Sullivan, Joe Lacy and H.L. Goodwin Center of Excellence for Poultry Science University of Arkansas Division of Agriculture Funded by American Recovery and Reinvestment Act under The Department of Energy award DE-EE In Partnership with the Arkansas Energy Office and Arkansas Resource Conservation District Councils

2 Weeks Summer Weekly Energy Consumption Eight Week Grow-out August 1, 2006 September 20, 2006 Lighting Fans Feed Augers kwh One House

3 Poultry Operation Energy Saving Opportunities: Why Lighting? Feed augers/movement motors are a small percentage of the overall energy consumption little opportunity to improve efficiency. Fan motors are a high percentage of the overall consumption but have a higher replacement cost relative to the energy efficiency gains. Lighting efficiency improvement appears to offer the best opportunity for savings.

4 Incandescent Lighting Many poultry houses utilize incandescent bulbs Dimmable Low initial/replacement cost (50 /60 watt bulb) Least efficient lighting source Heating a metal filament till it glows Bulb production phasing out in next few years

5 Summer Flock Electricity Consumption Eight Week Grow-out Period One House 7275 Lighting (31%) Fans/Sump Pumps (63%) Feed Augers, Misc. (6%) Total 0

6 Winter Flock Electricity Consumption Six Week Grow-out Period One House 5415 Lighting (40%) Kilowatt-Hours Fans/Sump Pumps (56%) Feed Augers, Misc. (4%) Total

7 Alternative Lighting Options Cold Cathode Fluorescent Lighting (CCFL) Dimmable Compact Fluorescent Lighting (DCFL) LED (Light Emitting Diode) Lighting In 2006 LED lighting not available for poultry house usage, therefore CCFL and dimmable compact fluorescent were choices evaluated

8 While Efficient: DCF and CC Have Challenges Dirt accumulation on CFL bulbs significantly reduces light output DCFL and CC bulbs sensitive to power fluctuations, resulting in a high failure rate CFL contain mercury, disposal challenges LED bulb options came on market 3 years ago Initial LED testing began at ABRF unit in November 2009

22 Project Outline Phase 1- Field Demonstration of LED bulbs suitable for poultry production Coordinated by the U of A Division of Ag Poultry Science Compared bulbs previously tested at U of A Farm to incandescent, cold cathode and DCFL Utilized 20- broiler farms in Arkansas 16 complexes participated All houses were tunnel ventilated, solid side walls or dark curtains Flock performance-energy use monitored for several flocks Began installations in March finished in July

27 Cold Cathode Cold Cathodes Fluorescent Light bulbs 8 Watt 325 lumens 4100 Kelvin Frosted bulb Dimmable No warranty

28 Dimmable Compact Fluorescent 15 Watt Dimmable 1,100 lumens 8,000 hour life Base Must meet ANSI C for use in standard E26 sockets

29 Brood Lights All farms had options of either 23 or 26 watt non-dimmable fluorescent bulbs Drop ceiling houses- 23 watt 1,600 lumens 12,000 hour life span High ceiling-26 watt 1,800 lumens 10,000 hour life span

30 Light Intensity Measurements For each farm-select one house Take 120 readings across the house Every 10 feet for 150 feet 8 readings are taken across the house and averaged Readings are taken: At each side wall Each inside water line Each Feeder line 2 readings off center For this presentation light intensity as measured in foot candles were averaged

31 Participating Producers Background Almost all were using: 100 W incandescent for brood 60 W incandescent for grow W sodium for brood 1- using fluorescent tubes 2- using 110 W for grow 1-using 75 W for grow 1-using 15 W DCF-just really wanted to try LED Majority of houses wide by long

48 Next Gen LED 50 bulbs/house- $35/NG LED- 50% rebate Cost of bulbs to retrofit 1 house $875 Electric cost = $0.10/KwH $ Savings/house per flock Estimated payback time 7 flocks/year = 1.0 years 6 flocks/year = 1.25 years Does not include the cost of compact fluorescents ~2.60 each

49 How do We Improve Life of CFL Bulbs need to be burned in Turned on for hours straight Do not dim below 10% Utilize an incandescent on the circuit to provide enough resistance so dimmer can detect and properly dim Use caution when cleaning Don t buy cheap bulbs

50 Summary-LED Lighting Provides significant energy savings Far more durable than CFL and CC LED bulbs support good bird performance So far bird performance as good as if not better than on previous lighting Do have dark areas between LED bulbs May need to rethink brood bulbs for more light initially so lamp lumen loss not as dramatic
