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!

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 <$1,700/House
• Expect Additional Power Rate Increases
• More Farms Facing Demand Metering Surcharge
Hen House Lighting Test Results
• $1,850/House Electrical Savings Per 44 Week Flock
• Power Co. Recently Started Demand Metering (~$0.035)
Original 150 Watt HPS Layout
• No Loss In Flock Performance (1 Egg/Hen/Yr = $350-$375)
• Floor Eggs Cut In Half; Slightly Lower Hen Mortality
• No Maintenance & Repair Expense With CFLs
• Lighting Amps @ Panel Reduced From ~50A To ~20A
• Reduced Power Usage - Saved 54.5 kWH & $6.02 Per Day
(16,800 kWH Per 11 Month Flock Cycle)
• Demand Metering Delayed ~1½-2 Months ($1.50-$1.75/Day)
23 Watt/1,600 Lumen CFL Layout Tested
(<=Optional)
• Plan: Replace All Lamps Every 2 Flocks (10-11,000 Hrs)
• Savings: Year 1 = $150; Year 2 & Beyond = $1,700
(Plus Any Savings From Demand Metering Delay)
Why Change Broiler House Lighting?
• LEDs Not Adequate Or Cost-Effective For Hen Houses
• Non-Dim CFLs Make Best Economic Sense For Hen Houses
Goals Of Broiler House Lighting
• Brood - Concentrate Light Over Feeders/Drinkers.
• Goals: 1) Extract Full Genetic Potential By
Influencing Behavior & 2) Reducing Power Bill
• After Turnout, Dim Progressively & Smoothly.
• Incandescent Bulbs: >85% Heat; <15% Light
• Co. Lighting Programs & Premium Pay Specs Vary.
• Incandescent Lights Can Be 25+% Of Power Bill
• In General, Target 3-5 fc @ Brood Over Feeders;
Then Dim Until End Of Growout.
• Reduce Lighting Costs 70-85% By Replacing All
Incandescent Lights With Low Wattage LEDs
(Typically ~8,000-10,000 kWH/House/Year)
• Fill Extreme Dimming Needs Of Catch Crews.
• Use Low Wattage Uniform Dim LED Grow Lights
• Supplement With Non-Dim CFL Broods At Lowest
Wattage Necessary To Reach Target Brood fc.

Observations In Most Older Houses
New Broiler House Lighting Layouts
• New Houses Are Easy - Full Flexibility With Specs.
• Typical Layout-Past Decade: 2 Circuits Alternating
Over Each Feeder – 1 Dim & 1 Non-Dim , 10’ OC.
• Use Nickel Plated Brass Sockets. No Oxidation.
• Avoid “Jelly Jars” - Causes Heat Buildup.
• Issue Is With Retrofitting Older Houses, Not New
Brood
Off-Brood
Lighting Retrofits For Broiler Houses
• Corroded/Oxidized Sockets - Wreak Havoc With
CCFL/CFL Bulbs, Shortens Life & Affects Dimming
• Have Full Elect & Gen Checkup Before Starting On Lights!
• Analog Dimmer Curves Designed For Incandescents
• Same Lighting Goals As New Houses
• Some Digital Dimmers May Still Not Have Smooth Curves
For CCFL, CFL & LED Bulbs
• Usually Possible To Use Existing Wiring 20’OC Circuits
(Avoid $1,400-$1,800 Re-Wiring Cost)
• Diff. LED Brands Have Diff. Dimming Components
• <25 Ohm Ground A Must For New Digital Dimmers
• 24 Hour Burn-In Of CCFL/CFL Bulbs For Long Life
• White Down Ceiling Reflects >¼ fc More Than Black
• Don’t Dim CCFL/CFLs Below 10% Full Intensity
• Difficult & Expensive To Achieve In High Ceiling Houses
Without PARs &/Or Reflectors. (Light Shines Up, Too!)
• Catch Crews Want It Very Dim, But Too Dim Quickly
Damages CCFL/CFLs (Key = Flicker/Strobe).
Typical Broiler House Retrofit Lighting Layout
• CFLs Over 26W Size Cost Much More & Have Shorter Life
One Good Retrofit Solution
On 20’ Center Spacing Over Feeders:
Use CCFL, Dim CFL, Or LED & Add 40-55 Watt CFLs
In Brood Center To Get ~3 fc @ Feeder
Brood
Off-Brood
= 2 Dimmable Grow Light Circuits (60-100 Watt Incand.)
Incandescents Replaced With 8 Watt LEDs
= 1 Non-Dim Brood Light Circuit (100-150 Watt Incand.)
Incandescents Replaced With 23-55 Watt Spiral CFLs
No Need To Re-Wire; Use 3 Existing Circuits, 20’ OC
LED/CFL - Best Economics & Saves Most Energy
Problem: Get ~3+ fc @ Feeder; Center Much Higher (5-9 fc)
Consider 2-In-1 Socket Splitter Over Feeders With 1 8W
LED & 1 18-26 W Non-Dim CFL With No Center
Brood Lights. After Brood, Switch Off All Non-Dim
CFL Bulbs & Dim. Good To Match 0K On Bulbs.
Use Dim Bulbs Without Splitters In Off-End
Result: Get 3-5 fc @ Feeder, Only 2-3 fc In Center

LEDs – Good Tech Solution, But Cost?
CCFL/CFL Problems Seen Since 2008
•
•
•
•
•
•
•
•
•
•
Bad Quality, High Failures, Breakage & Warranty Issues
Significant Lumen Depreciation (~15-25%/Year)
New 8W CCFL Only Has 325 Lumens & Loses 60-75+/Year
Hard To Clean, Fragile & Discoloring
Low-End Dimming Increases Bulb Stress (Shorter Life)
Lumen Deprec. Means Dimmer Settings Must Change Often
High Post-Washdown Failure Rates
Shorted/Corroded Sockets – More Ohms, Heat, Mini-Arcs
Lost Flock Performance Over Time
Lots Of Frustrations: Grower--Company--Supplier
• Higher Mgt Detail Required For CCFL/CFL Success
• But Energy Use & Cost Much Lower Than Incandescents
LED Demos/Tests – North Alabama
Goals:
•Test, Demonstrate & Compare Alternative LEDs In
Commercial Broiler Housing
•Measuring Intensity, Uniformity, LD & Longevity
•Grower/Integrator Observations & Feedback Critical
•Compare Cost-Effectiveness Of Various Models
