If you've ever fumbled with a lamp switch late at night or worried about leaving lights on while away from home, a lighting timer can be a tiny gadget that makes a massive difference. From saving energy and adding security to integrating with your smart home, lighting timers and accessories come in a lot of flavors. In this guide I'll walk you through the types, the best stores in the US to shop from, top product picks for different needs, installation tips, and money-saving examples so you can buy and install with confidence.
Think of a lighting timer as autopilot for your lighting. Instead of remembering to turn lights on and off, the timer follows a schedule you set. That means lower electric bills, fewer wasted hours with lights on in empty rooms, and better curb appeal and security when you're out of town. It's one of those low-effort, high-impact upgrades—like adding a smart thermostat but cheaper and faster to install.
You don't have to change your habits to see savings. A timer does the remembering for you. Program outdoor lights to turn on only at dusk and off in the middle of the night, or set interior lights to match your routine so you never come home to a dark house. Over weeks and months, those small changes add up on your electric bill.
Timers can mimic occupancy by turning lights on and off at different intervals. For anyone who travels or has a second home, that's an inexpensive trick to deter would-be burglars. Pair a timer with a few lamps inside and a porch light outside, and it creates the appearance that someone’s always home.
Not every timer fits every situation. Picking the right type depends on whether you want simplicity, precision, or advanced automation. Here's a quick breakdown so you can match features to your needs.
These are the classic dial timers you push segments down around a 24-hour clock. Pop it into an outlet, plug a lamp into the timer, and you’re done. They’re cheap, reliable, and easy to use when you just want lights to come on and off at fixed times.
Digital timers offer more flexibility—multiple on/off events per day, weekday/weekend scheduling, and battery backup so you don't lose your settings in a power outage. They’re great for people who want more control without dealing with a smartphone app.
If you’re building a smart home, Wi‑Fi timers (or smart plugs) give you app control, voice assistant compatibility, and remote access. Want your porch light to come on five minutes before you pull into the driveway? Smart timers can do that, and some integrate with motion sensors and routines.
Dusk-to-dawn sensors switch lights based on ambient light, not a clock. They’re perfect for outdoor fixtures that should automatically run from nightfall to morning, and they remove the need to reset seasonal schedules as daylight changes.
With dozens of models available, focusing on a few key features helps you avoid buyer’s remorse. Here are the must-check items that determine performance and longevity.
Decide how many on/off events you need per day and whether you want weekday/weekend differences. If you travel often, look for randomize or “vacation” modes that vary on/off times to appear lived-in.
Every timer lists a maximum wattage or amp rating. Make sure your lights, especially strings of incandescent or halogen bulbs, don’t exceed the timer’s capacity. For LED loads, check whether the timer supports low-wattage electronic drivers so you don’t see flicker.
Outdoor timers need to be weather-resistant. Look for devices rated for outdoor outlets or enclosed in weatherproof housings. If you’re wiring an in-wall timer for an outdoor fixture, the switch itself should be suitable for the circuit and mount.
Where you buy can affect price, returns, and convenience. Here are reliable nationwide options—each with strengths depending on whether you want in-store pickup, wide selection, or quick shipping.
Home Depot carries a broad selection—mechanical, digital, in-wall, and smart timers—from brands like Intermatic, Honeywell, and Leviton. Their product pages often include specs and reviews, and you can choose in-store pickup the same day in many locations. If you prefer to see the item before buying, Home Depot is a solid stop.
Lowe’s is another major home improvement chain with comparable offerings. They tend to stock a wide range of smart switches and timers compatible with popular smart ecosystems. Pro tip: check both Home Depot and Lowe’s for price and model differences before you buy.
For budget-friendly plug-in timers and basic smart plugs, Walmart is convenient. You’ll find cheap mechanical timers and basic digital models, plus fast shipping on many items. It’s a good option when price and convenience matter most.
Amazon shines for selection. If you want niche models, international brands, or the latest smart timers, Amazon likely has it. Read reviews carefully and verify seller ratings for electrical products. Prime shipping makes it easy to get a replacement fast if something arrives damaged.
Ace’s neighborhood stores are handy for emergency replacements and friendly hardware advice. Local staff can often recommend models based on common regional needs—think cold-weather performance and outdoor durability.
For Wi‑Fi timers and compatibility with Alexa, Google Home, or Apple HomeKit, Best Buy and specialty smart home shops offer hands-on demos and staff who understand app pairing and network requirements.
Not all timers are equal. Below are suggestions matched to typical scenarios so you can pick faster—like a friend handing you the right tool.
Choose a photocell or a robust digital timer in a weatherproof enclosure. Brands like Intermatic offer outdoor-rated timers that can handle heavy loads and are built to last through rain and humidity. Pair with a motion sensor if you want light only when motion is detected.
If you want voice control and remote automation, go with a Wi‑Fi smart plug or a smart in-wall timer that supports your ecosystem (Alexa, Google, or HomeKit). Look for devices with firmware updates and an active support community.
Mechanical plug-in timers are cheap and reliable. They do one job well: turn devices on and off at fixed times. For a few dollars, you get years of service with almost no setup time.
For landscape lighting or circuits with many bulbs, choose a commercial-grade timer rated for higher amperage. Hardwired timers designed for 20-amp circuits are the right choice for whole-outlet control or large loads.
Installing a plug-in timer is straightforward, but hardwiring an in-wall timer or replacing a switch requires care. Always follow manufacturer instructions and local electrical codes. When in doubt, hire a licensed electrician—it's worth the peace of mind.
Plug-in models simply go into the outlet and then accept the lamp or device plug. For outdoor outlets, use a weatherproof enclosure or an outdoor-rated timer. Test the schedule for a few days to fine-tune on/off times.
Turn off power at the circuit breaker before replacing a switch. Use a voltage tester to confirm the circuit is dead. Some modern timers require a neutral wire; check your switch box first. If you don’t have a neutral or you’re uncomfortable with wiring, hire an electrician. Improper wiring can damage devices or create a fire hazard.
Most timers run for years without fuss, but when problems crop up, these tips often fix them fast.
Timer lost settings after a power outage? Check if it has a battery backup and replace the battery. Flicker with LEDs? Make sure the timer is rated for electronic loads and avoid mixing LEDs with high-wattage halogen strings on the same timer. If a timer won’t power the load, verify wattage limits and test the outlet or circuit for power.
Keep outdoor timers off the ground and away from direct spraying from sprinklers. Replace rubber gaskets if they start to crack, and inspect connections yearly for corrosion or water intrusion.
Let’s put some numbers to it so the idea sticks. Imagine an outdoor porch light with a 60-watt bulb left on 12 hours a night. That's 720 watt-hours per night, or about 0.72 kilowatt-hours (kWh). At $0.15 per kWh, that’s roughly $0.11 per night, or about $33 per year. Set a timer to run the light only 6 hours a night instead of 12 and you cut that cost in half. Multiply that across multiple fixtures and you quickly pay for the timer.
Look for seasonal sales—spring and fall often bring discounts on outdoor and electrical accessories. Compare models across Home Depot, Lowe’s, Amazon, and Walmart for the best price and warranty. If a store offers price matching, bring proof of the lower price to save more. Finally, read reviews that mention long-term reliability and real use cases like cold-weather performance or LED compatibility.
Choose products with a decent warranty and UL or ETL listing for safety. A good warranty and safety certification are your best hedge against short-lived gadgets that quit after a season.
Lighting timers are small devices with outsized benefits—lower bills, added convenience, and better home security. Whether you choose a simple mechanical timer from Walmart, a robust digital model from Home Depot or Lowe’s, or an advanced Wi‑Fi timer from Best Buy or Amazon, the right choice depends on how much control you want and where the timer will be used. Start with a clear idea of the load, environment, and how you want the timer to behave, and you’ll save money and frustration in the long run.
Ready to add automation to your lighting? Think through the features above, check load ratings, and pick a retailer that fits your delivery or pickup needs. With a little setup, your lights will run like clockwork—literally.
Conclusion: Lighting timers are one of the easiest, most cost-effective ways to upgrade your home’s convenience and security. With options across major US retailers and models to fit every budget and technical skill level, there’s a timer that’s right for you. Install carefully, match the timer to your load, and enjoy the hands-off control and savings.
