Overview
Lighting is an important management tool for small and backyard poultry flocks. Proper light levels and day‑length help regulate feed intake, growth, behavior, and egg production. LED (light‑emitting diode) bulbs have become a preferred lighting option for many poultry keepers because of their efficiency, durability, and spectrum control.
In a real-world scenario, a small flock of laying hens stopped laying eggs entirely in early June – when they should have been at their peak in egg production. After considering nutrition, health status, and any other external stressors that could potentially be impacting egg production, it was noted that the LED bulbs in the yard lights around the coop were aging, with some already having gone out. Suspecting a potential flickering problem, all of the LED bulbs were replaced with new ones. Within 3 weeks, the flock had begun to lay again and were back to full production by the end of the month. As a side note, human eyes do not perceive the flicker as it begins in LED bulbs.
This Poultry Tip summarizes the advantages and disadvantages of LED lighting for small poultry flocks, particularly those maintained for table egg production.
Benefits of LED Bulbs in Backyard Poultry Housing
1. Energy Efficiency
- LEDs use far less electricity than incandescent bulbs, while they are similar in energy efficiency to compact fluorescent lamps (CFLs). Using LED or CFL bulbs helps to lower operating costs for long-term supplemental lighting during winter months or in enclosed coops.
2. Long Lifespan & Durability
- LED bulbs typically last for thousands of hours, reducing the frequency of bulb changes—especially helpful in coops with limited or difficult access.
- Modern LEDs maintain up to 70–80% of their original light output over a couple years, but the output (lumens) decreases over time and can lead to flickering as mentioned in the field report.
3. Low Heat Output
- LEDs emit very little heat, reducing the risk of fire—a critical safety consideration in small coops with bedding materials. Their cool operation also helps avoid overheating birds in warmer climates.
4. Consistent Light Quality
- High-quality LEDs provide steady illumination when properly matched with compatible electrical components. Stable lighting promotes normal behaviors and supports consistent egg laying.
5. Suitable Light Spectrum
- Warm‑white LEDs (approx. 2700–3000K) provide a spectrum similar to traditional bulbs used in poultry production and are generally well accepted by birds.
Considerations & Downsides of LED Bulbs
1. Flicker Issues with Low‑Quality LEDs
- Chickens can perceive light flicker that humans cannot. Some inexpensive LEDs or incompatible dimmers may produce flicker, potentially causing stress, behavioral disturbances, or reduced productivity.
2. Compatibility Problems with Dimmers
- Backyard poultry housing using automatic dimming systems may experience dimming irregularities or premature LED failure if bulbs and dimmers are not properly matched. Many premature failures reported in poultry houses were linked to dimmer–LED incompatibility.
3. Higher Upfront Cost
- LED bulbs are initially more expensive than incandescent or CFL options, though they typically pay for themselves through lower energy use and longer life.
4. Limited Heat Contribution in Winter
- Because LEDs produce minimal heat, they cannot double as a heat source. While heat lamps are not recommended due to fire risk, some backyard flock owners accustomed to utilizing the warmth of incandescent bulbs to provide heat may need to provide another source of safe heating for very cold climates.
Lighting Recommendations for Backyard Flocks
- Provide 14–16 hours of light per day for laying hens throughout the year, particularly extending into the winter months as natural daylength wanes.
- Use warm‑white LEDs (2700–3000K) to maintain light intensity around 0.5 – 2.0 foot‑candles.
- Clean bulbs regularly to maintain brightness; dust accumulation reduces light output.
- Ensure dimmers, timers, and LEDs are compatible to avoid flicker or early bulb failure.
Key Takeaways
LED bulbs offer a highly efficient, durable, and safe option for lighting backyard chicken coops. When choosing LEDs, flock owners should prioritize warm‑white bulbs, check dimmer compatibility, and select quality brands tested for agricultural conditions to avoid flicker or early failure.
