Lumen Depreciation All Lights Depreciate, But At Very Different Rates! Two Sources Of Lumen Depreciation: 1) Physical Deterioration Over Time – Can’t Control 2) Accumulation Of Dust, Dirt & Debris – Can Control

Lighting Uniformity • Need Quantitative Measure Of Light Output At Bird Level - Wall To Wall, End To End (Index) • We Use CV (Std.Dev./Mean) On 25-Spot Grid Sample
Lower CVs Denote Improved Lighting Uniformity.

LED Myths • • • • •
My Bulb Has Better “Bird Lumens” & “Bird Footcandles” My Bulb’s Power Factor Saves Big On Amps & Power Bill My Bulb Gives Better Bird Performance (Pounds, FCR, Etc.) My Bulb Is Required By Your Integrator My Bulb Is The Only Bulb That Qualifies For Rebates
• • • • • •
A Watt Is A Watt – Basis Of Power Bill, Not Amps Or P.F. Power Factor Has Very Small $$ Effect On Power Bill Any Performance Claims Are Highly Questionable Integrators Do Not Require Specific Brands Many LED Brands Qualify For Rebate Programs Bulb Specs, Warranty, Performance & Cost – All Critically Important In Making A Smart Business Decision!

Plays Tricks On Eyes. Light Meter Is A Must For Correct Dim Levels
Pullet House Lighting • Use Low Light & Feed Restriction To Delay Sexual Maturity • Males & Females Usually Need Slightly Different Lighting Programs, Depending On Breed & Strain • Wide Variety Of Pullet Housing, Lighting Layouts, & Dimming Considerations. Specific Housing Layout, Breed, & Sex Situation Dictates Best Lighting Approach • Some Don’t Use Dimmers At All, Only Low Light (CFLs). Works, But Not Best. Flex. With Dimming, But Costs $$ • Cost Varies From $150-$1,000 Per House • Since Pullet Grower Pay Is ~Fixed, Little Upgrade Incentive • 3,0000K Or Lower Suggested – Company Decision • Better Synch Light Increase Ratios @ Move (10:1 vs. 6:1) • LEDs & Dimming - Help Stop Digging & Aid Synch Control
Reasons For Changing Hen House Lights • #1 Goal: Lower Power Bill While Maintaining Same Breeding & Laying Performance • Power Rates More Than Doubled Past Few Years • High Electrical Consumption By HPS (185+ Watts)
Hen House Test, 2009-13 • 12 Typical Clear Curtain Sided Hen Houses, 40’ X 400’ • Replaced 32 150Watt High Pressure Sodium Lights With 100 23 Watt Non-Dim CFL Bulbs (2,700 0K; 12,000 Hrs) • 1 House To Start – Under Close Company Supervision
• Non-Uniformity Of HPS Lighting & Shadowing
• 2 Rows ~ Over Nests On ~10’ Centers, Plus Supplements In Cool Cell & Fan Areas. Yields Uniform 5-8 fcs
• High Labor & Maintenance Of HPS
• Cost Of Rewiring & Bulbs 600+ FPM

Light Emitting Diode (LED) Is Great Newer Technology Evolving Rapidly. LEDs Run Cool, Dim Smooth, & Last. High Cost Issues, But Prices Trending Down Past Year Most CCFL/CFL Mgt Problems Disappear With LEDs Many Shapes & Styles, Most Between 3,0000K & 5,5000K Issues With Some LEDs: Diode Quality, Heat Sinks & Fins, Lumen Depreciation, Warranty & Light Spread/Uniformity • High $$ Bulbs Disappearing At Flock End? • NPTC Is Evaluating 25+ LED Brands/Models/Shapes

General LED Observations • • • • • • • • • • • • •
Few Failures @ 6+ Flocks – LEDs Reliable, Last & Low LD! Erratic Low-End Dimming With A Few, But Solvable Difference In Power Bills Insignificant Among LEDs A19s – Best Overall Lighting Uniformity; Lowest Cost PAR30s – Good Uniformity; Slightly Higher Cost PAR38s & Hybrids – Good Uniformity; Most Costly PARs/Hybrids Best In High Ceilings (More Lumens/Spread) Most LEDs Water/Air Tight. Little H20/NH3 Damage Seen Debris Buildup On Some Styles – Management Problem Seeing Move To Longer Warranties – 5 Years Seeing New 9-11W A19s With 800+ Lumens (Heat/Life??) Takes Time To Measure Length Of Effective Service Life Not Much Lumen Depreciation Seen In 1+ Year

LEDs Dim Smoothly & Much Lower. Seldom Flicker. Catch Crews Really Like LEDs - Hard To Abuse. Dimmer/Brand Differences - Handshaking Challenge Most Problems Seen @ Lowest Dimmer Settings Some Still Require 1 Incandesc/Circuit To Dim At All Unlike CCFL & CFL, Dimming Increases LED Life

• All Houses/Farms Similar, But Not Identical • No Significant Difference Seen Or Reported In: Mortality, ADG, FCR, Or Any Plant Issues • No Change Seen In Grower Settlement Or Ranking • Other Factors More Important Than Lighting • Birds Act More “Content” With Uniform Light • No Difference Seen In Light Color (0Kelvin) • Some LEDs Offer Excellent Economic Payback, But LEDs Are NOT A Performance Silver Bullet! Therefore, Cost & Warranty Are Critical!

Economics Of Lighting Retrofits Get A Professional Electrical Checkup First! If Existing Wiring Is OK: • ~$800-$2,500+/Hse For LEDs (With No Rebate) • Annual Power Savings: ~ $200+/100’ Of Length (A Watt Is A Watt) • Use LED-Grows & Non-Dim Spiral CFL-Broods • Different Situations; One Size Does NOT Fit All! • Do It Correctly Or Expect Failures! • LEDs Are Great, But Some Issues Still Remain, Especially Cost & Warranty
Questions & Discussion
Lighting Retrofit Summary • Incandescent & HP Sodiums Should Be Replaced With LEDs Or CFLs – Specific Situation Dictates Best Fit • Use Low Wattage LEDs Over Feeders, & Add Higher Wattage Non-Dim CFLs For Brood – Best Bang For The $$ • Clean Bulbs Often – Get The Light You’re Paying For • Don’t Leave $1,000-$1,200/Hse/Yr On The Table • 5 Year Warranties On LEDs Becoming More Common • Simple ROI Paybacks Measured In Flocks, Not Years • Some LEDs Are Cost-Effective, But Some Are Not Yet • If An LED Rebate Program Is Available, Jump All Over It! ***Ultimate Goal Is To Make A Wise Business Decision***
