LED lighting — light that steers the flock
Light is more than visibility. It decides how much the birds eat, how active they are, how they grow and — in layers — how many eggs they lay. LED saves power, dims smoothly and lets you control the colour. We explain how many lux to set, which colour to choose and how to build a light program.
verifiedFrom the team that has organised work on poultry farms for years.
Poultry see the world differently from people. Birds perceive a wider range of light, they are sensitive to flicker we don’t notice, and they react strongly to the rhythm of day and night. That is why lighting in a poultry house is not an extra but a tool for steering the flock: the light program (hours of light and darkness) sets the rhythm of feeding, activity and rest, while intensity and colour shape behaviour and welfare.
Why LED rather than fluorescent tubes or bulbs?
Old bulbs and fluorescent tubes light in steps, draw a lot of power and dim poorly — when dimmed they often start to flicker, which stresses the birds. LED uses far less energy, dims smoothly from 0 to 100% and lets you pick the light colour. The key point is that good LED fittings dim without flicker (flicker-free), so the light stays calm for the birds’ sensitive eyes at every brightness level.
What to look at in LED lighting
The choice depends on the production type, the birds’ age and the conditions in the hall — humidity, washing and the geometry of the building.
Fittings resistant to moisture and washing
A poultry house is humid, dusty and pressure-washed. Fittings need an adequate sealing rating (IP class) and a closed, smooth cover that can be washed and disinfected. A leaky fitting fails quickly or starts to flicker.
Smooth dimming 0–100%
Smooth brightness control across the full range is essential. It lets you run a gentle dawn and dusk, match intensity to the birds’ age and save power. It matters that dimming works without flicker at every level, not only at full brightness.
Colour temperature and colour by species
The light colour (warm, neutral, cold) affects bird behaviour. Broilers and layers may respond differently to warm and cooler light. Some manufacturers offer fittings with a colour tuned specifically for poultry — it is worth following their guidance.
Even intensity across the hall
What counts is not the number of lux alone, but that the light is even over the whole floor. Bright patches and dark corners disturb behaviour — birds gather in bright spots and avoid dark ones. Good fitting layout gives uniform intensity without shadows.
Light-program control
It pays to connect the lighting to a controller or timer that runs the light program: hours of light and darkness, a gentle dawn and dusk, brightness levels through the day. The controller does this automatically and repeatably, without manual switching.
Flicker-free operation
Birds see flicker that people miss. Flickering light — especially when dimmed — stresses the flock and harms welfare. Flicker-free LED fittings keep a calm, steady light at every brightness level, which is safe for the birds’ eyes.
Lighting step by step
- 1
Match intensity to age and production
Light intensity (in lux) is set differently for young and older birds, and differently for broilers than for layers. At the start it is usually brighter, so chicks find feed and water, and intensity is then lowered. Take the exact values from the guidance of your bird or fitting supplier.
- 2
Position the fittings evenly
Lay out the fittings so the light is even over the whole floor — no dark corners, no bright patches. Spacing between fittings, their height and the beam angle all matter. Birds gather where it is brighter, so uneven light means uneven use of the hall.
- 3
Choose the colour and check the fittings
Pick the light colour in line with your supplier’s guidance for your production type. While you are at it, make sure the fittings are sealed (IP class) and have a cover that withstands pressure washing and disinfection between batches.
- 4
Set the light program
Build the schedule of light and dark hours by flock age and supplier guidance. The light program steers feeding, activity and rest. In layers there is a daily rhythm that affects egg production — stick to a proven schedule and don’t change it chaotically.
- 5
Enable a gentle dawn and dusk
Instead of switching the light on and off abruptly, set a smooth brightening in the morning and dimming in the evening. A gentle dawn and dusk reduce stress and panic in the flock and give the birds time to settle calmly for the night.
- 6
Check intensity and clean the fittings
Measure intensity with a lux meter at several points in the hall, at bird height, and check it matches your plan. A dirty cover can rob a lot of light, so fittings need regular cleaning — especially after washing and before a new flock is placed.
Frequently asked questions about poultry house lighting
Why LED instead of fluorescent tubes or bulbs?add
Because LED uses far less power, lasts longer and dims smoothly across the full range. Fluorescent tubes and bulbs dim poorly and often start to flicker when dimmed, which stresses the birds. Good LED fittings dim without flicker and let you match the light colour to the species and the age of the flock.
How many lux should there be in a poultry house?add
It depends on the birds’ age and the production type. At the start it is usually brighter so chicks find feed and water, and intensity is lowered later in rearing. There is no single number that fits everything — follow the guidance of your bird or fitting supplier and check the intensity with a lux meter at bird height.
Which light colour for broilers and which for layers?add
The light colour affects behaviour and may act differently in broilers than in layers. Some manufacturers offer fittings with a colour tuned specifically for poultry. The surest approach is to follow the guidance of the fitting or bird supplier for your particular production type, rather than picking a colour by eye.
Why does flicker-free dimming matter?add
Because birds see flicker that we don’t notice. Cheap fittings often start to flicker exactly when dimmed, and flickering light stresses the flock and harms welfare. Flicker-free lighting keeps a calm, steady light at every brightness level, so it is safe for the birds’ sensitive eyes.
