Key takeaways
- Laying is driven by day length. Penn State Extension guidance for mature laying hens is about 16 hours of total light per day, added gradually.
- Add the extra light in the early morning, not the evening, so hens go to roost with the natural sunset.
- A timer is not optional. Consistency matters more than brightness, and a dim, warm LED is plenty.
- Use outdoor-rated, low-heat LED gear, keep cords out of reach of birds, and have a licensed electrician handle any hardwired fixture.
- Lighting is a choice, not a requirement. Many keepers let hens rest through winter, and both approaches are reasonable.
The short answer
For most backyard coops, the best setup is a low-wattage, warm-white LED light on an outdoor-rated timer, turned on a few hours before sunrise. If you have safe power at the coop, a plug-in LED kit with a built-in timer is the simplest route. If you don't, a rechargeable or solar coop light with a timer avoids running a cord.
Whatever you buy, the light is only half the answer. The other half is the schedule. Our step-by-step guide to supplemental light for winter eggs walks through setting it up. This page is the gear list.
| Setup | Tier | Best for | Main trade-off |
|---|---|---|---|
| Plug-in LED coop kit with built-in timer | $ | Coops with an outdoor outlet nearby | Needs a safe cord route |
| Rechargeable LED light with timer | $–$$ | Small coops without power | Needs charging, and cold shortens battery life |
| Solar coop light with timer | $$ | Sunny sites without power | Short winter days may not recharge it fully |
| Outdoor plug-in timer (mechanical or digital) | $ | Turning any existing light into a timed light | You adjust it as sunrise shifts |
| Astronomical or smart timer | $$ | Hands-off scheduling | App setup, and Wi-Fi must reach the coop |

Why hens stop laying in winter, and how light helps
Hens respond to day length. As days shorten in fall, their bodies read that as a signal to slow or stop laying, and many flocks also molt around the same time. Supplemental light works by extending the "day" your hens experience, so their bodies keep getting the long-day signal.
Penn State Extension's guidance for mature laying hens is to provide about 16 hours of light per day, to add artificial light in the early morning and let the natural sunset end the day, and to change the photoperiod slowly, by no more than an hour a week. That's the schedule the gear below is built around.
Here's a worked example. Say your target is 16 hours, and on a December day your location gets about 9.5 hours of daylight (check a local sunrise and sunset table for your real number). You'd add about 6.5 hours before sunrise, but you'd work up to it gradually rather than jumping there in one week. If sunrise is 7:30 a.m., the light would eventually switch on around 1:00 a.m. and off after it's fully light.
Why morning light, not evening light
If the light switches off after dark, your hens are suddenly in pitch black, often off the roost. Chickens don't see well in the dark, and some will spend the night on the floor. Adding light in the morning avoids that problem: the timer turns the light on before dawn, sunrise takes over, and hens go to roost naturally as the sun sets.
The best coop lights for winter laying
Plug-in LED coop light kit with built-in timer
$Kits sold for coops usually include a warm LED bulb or strip, a cord and a timer, so you don't have to piece a setup together. Look for an outdoor-rated plug, a sealed or covered light, and a timer you can set to a morning on-time.
Why we like it
- Simple one-box setup
- low heat and low power draw
- warm-white output suits hens
Keep in mind
- Needs a safe, outdoor-rated outlet
- cord routing must keep wires away from pecking and chewing
Rechargeable battery LED coop light with timer
$–$$A USB- or battery-powered light with a built-in timer avoids cords entirely. It's a good fit for backyard coops far from the house. Plan on a charging routine and a spare battery pack, because cold weather shortens run time.
Why we like it
- No wiring or extension cords
- easy to move and remove
- good for small flocks
Keep in mind
- Needs regular charging
- cold reduces battery life
- brightness may not suit a large walk-in coop
Solar coop light with timer
$$A small solar panel charges a battery during the day, and the timer runs the light before dawn. It's attractive for off-grid coops, but winter is exactly when solar output is lowest. Check the manufacturer's stated run time, and mount the panel where it gets clear winter sun.
Why we like it
- No electric bill or cords
- good for off-grid setups
- works year-round for other uses
Keep in mind
- Short, cloudy winter days may not fully recharge it
- panel placement matters a lot
Outdoor-rated plug-in timer
$If you already have a safe light in the coop, a weatherproof plug-in timer is the cheapest upgrade. Mechanical timers are simple and tough. Digital timers are more precise and let you set different times on different days.
Why we like it
- Very low cost
- works with any plug-in light
- mechanical models are durable
Keep in mind
- You'll adjust the on-time as sunrise shifts
- make sure it's rated for outdoor or damp locations
Astronomical or smart outdoor timer
$$An astronomical timer or outdoor smart plug adjusts to your local sunrise and sunset, so you don't reset it every couple of weeks. Some smart plugs let you check or adjust the schedule from your phone.
Why we like it
- Tracks sunrise automatically
- fewer manual adjustments
- some offer app control
Keep in mind
- Smart plugs need Wi-Fi at the coop
- check outdoor and damp ratings in the listing
Enclosed vapor-tight LED fixture
$$Coops are dusty and damp, and a sealed fixture keeps dust and moisture out of the light. This is the most durable option for larger coops, but it's a hardwired fixture, so it should be installed by a licensed electrician.
Why we like it
- Sealed against dust and moisture
- durable
- good even light for chores
Keep in mind
- Hardwired, so professional installation is required
- overkill for a small backyard coop
How to choose a coop light
Power source first
Your power situation narrows the choice quickly:
- Outdoor outlet within reach: a plug-in kit or any safe LED plus an outdoor timer.
- No power, sunny site: solar with a timer.
- No power, small coop: rechargeable battery light.
- Walk-in coop with wiring: an enclosed fixture, installed by an electrician.
If you're thinking about running power to the coop, read chicken coop winter electricity first, and have a licensed electrician do any permanent wiring.
Warm, dim and steady
You don't need a bright light. Penn State Extension notes hens need only a low light level for laying stimulation. A warm-white LED is a common choice, and it runs cool, which matters in a coop full of dry bedding and feathers.
Placement
Mount the light high and out of reach, where hens can't perch on it or peck the cord. Aim it so it lights the feeder and floor area, not straight into the nest boxes, since hens prefer dim, private nests.
Safety: the part not to skip
Electrical equipment in a coop lives with dust, moisture, ammonia and curious birds. LEDs run far cooler than heat lamps, but any electrical device can cause trouble if it's damaged, dusty or installed badly.
- Use outdoor-rated equipment and plug it into a GFCI-protected outlet.
- Choose LEDs over incandescent or heat bulbs. They run far cooler.
- Secure the light so it can't fall into bedding.
- Keep cords out of reach of pecking birds and chewing rodents.
- Clean dust off fixtures regularly, as Penn State Extension also advises.
- Leave hardwiring to a licensed electrician. Don't DIY new circuits or fixtures.
Mistakes to avoid
- Adding all the light at once. Build up gradually, about an hour a week at most, per extension guidance.
- Evening-only lighting. Birds get stranded in the dark when the timer clicks off.
- Forgetting to adjust the timer. Sunrise moves through winter. An astronomical timer solves this.
- Lighting a molting flock and expecting eggs. Molt runs its course regardless of light.
- Lighting pullets too early. Ask your extension service or vet about lighting young birds that haven't started laying.
- Stopping suddenly in spring. Taper off rather than switching the light off one day.
Timing and Black Friday tips
The best time to set up a coop light is before days get too short, so you can ease hens into the schedule. If you're buying in November, Black Friday is a good time to pick up timers and smart plugs, which are often part of broader home sales. Buy outdoor-rated versions, even if they cost a little more.
Frequently asked questions
How many hours of light do chickens need to lay eggs in winter?
Penn State Extension's guidance for mature laying hens is about 16 hours of light per day, including natural daylight, with changes made gradually. Many keepers choose not to add light at all and let hens rest.
Should I put the coop light on in the morning or the evening?
In the morning. Adding light before sunrise lets the natural sunset end the day, so hens go to roost normally instead of being plunged into darkness when a timer switches off.
What kind of light is best for a chicken coop?
A low-wattage, warm-white LED on a timer. LEDs run cool and use little power. Avoid heat lamps as light sources because they're a known fire risk.
Can I use a solar light in a chicken coop?
Yes, if the panel gets good winter sun. Short, cloudy winter days may not fully recharge the battery, so check the manufacturer's run-time figures and panel placement.
Is it cruel to add light to a chicken coop in winter?
It's a personal choice. Supplemental light is widely used, and many keepers also let their hens rest over winter. Keep changes gradual, stay within extension guidance, and don't expect molting hens to lay.
Do I need an electrician for a coop light?
For any hardwired fixture or new circuit, yes. Plug-in lights and timers can go into an existing outdoor-rated, GFCI-protected outlet. Have a licensed electrician add or wire anything permanent.
