When it comes to garage door openers, lighting is more than just convenience—it’s about safety, efficiency, and optimal performance. A common question among homeowners is: “What size light bulb goes in a garage door opener?” While it may seem like a small detail, using the correct light bulb size and type can significantly affect the functionality and lifespan of your opener.
This comprehensive guide covers everything you need to know about garage door opener light bulbs—from sizing and wattage to energy efficiency and smart lighting options. If you’re replacing a burnt-out bulb or upgrading your garage’s lighting, this article will help you make an informed decision.
Why Lighting in a Garage Door Opener Matters
Before diving into bulb sizes, it’s important to understand why lighting in your garage door opener is critical:
- Safety: A well-lit garage helps prevent trips, falls, and accidents, especially when entering at night.
- Security: Built-in lights can deter intruders and enhance motion detection systems.
- Convenience: Lights that activate when the door opens make it easier to load, unload, or access tools and storage.
- Compatibility: The wrong bulb type or size can cause electrical issues or interfere with the opener’s remote signal.

What Size Light Bulb Goes In A Garage Door Opener?
The standard light bulb size for most garage door openers is either an A19 or A15 bulb, depending on the model and manufacturer.
Common Bulb Sizes and Specs:
| Bulb Type | Bulb Code | Base | Wattage | Typical Use |
|---|---|---|---|---|
| A19 | A19 | E26 | Up to 60W | Most residential garage door openers |
| A15 | A15 | E26 | Up to 40W | Compact units with smaller housings |
| LED | A19 or A15 | E26 | 8W–12W (60W equivalent) | Energy-efficient and long-lasting |
| CFL | A19 | E26 | 13W–15W | Less common due to cold start issues |
| Rough Service | A19 | E26 | Up to 60W | Vibration-resistant for opener motors |
Note: Always check your garage door opener’s manual or housing label before purchasing a replacement bulb.
Wattage Limits: How Much Is Too Much?
One of the most important considerations when selecting a garage door opener bulb is maximum wattage. Using a bulb with wattage above the manufacturer’s limit can:
- Overheat the socket
- Melt the plastic housing
- Cause short circuits or fire hazards
General Wattage Guidelines:
- Chamberlain / LiftMaster: Typically supports bulbs up to 60 watts
- Genie: Often recommends 40-watt bulbs
- Craftsman: Varies by model; most cap at 60 watts
- Modern openers: Encourage the use of LEDs rated at 8-10W (60W equivalent)
Best Bulb Types for Garage Door Openers
Choosing the right type of light bulb matters just as much as the size. Let’s compare the most popular options:
1. Incandescent Bulbs
- Traditional and widely compatible
- Short lifespan (750–1,000 hours)
- Can handle vibration (rough service versions)
Downside: Not energy efficient and banned in many states due to energy laws.
2. LED Bulbs
- Long lifespan (up to 25,000 hours)
- Energy-efficient (use 80–90% less electricity)
- Stay cool and reduce fire risk
Caution: Some LED bulbs can interfere with remote signal reception, especially if not garage-opener-safe.
3. Rough Service Bulbs
- Designed to withstand vibration from motor operation
- Better suited for traditional units without shock absorbers
4. Garage Door Opener-Compatible LED Bulbs
Some manufacturers, such as Chamberlain and Genie, produce specialty LED bulbs designed not to interfere with remote signals. These bulbs are vibration-resistant, weather-tested, and optimized for openers.
Light Bulb Interference Issues
A surprisingly common issue is that some LED or CFL bulbs emit radio frequencies that can interfere with the opener’s receiver, making your remote control less effective or completely unresponsive.
Symptoms of Interference:
- Remote works only at close range
- Door doesn’t open or close consistently
- Delayed response
Solutions:
- Use garage-door-compatible LEDs
- Avoid cheap, off-brand LED bulbs
- Look for FCC-compliant bulbs
- Check manufacturer recommendations
How to Change the Light Bulb in a Garage Door Opener
Here’s a step-by-step guide:
- Unplug the opener from the power outlet (or shut off the circuit breaker).
- Allow the current bulb to cool completely if it was recently on.
- Remove the light cover or lens (usually slides or unscrews).
- Gently unscrew the old bulb.
- Insert the correct bulb type and size—avoid forcing it.
- Replace the lens cover and plug the opener back in.
Tip: If your opener has two light sockets, you can install a bulb on each side for better coverage.
Lighting Features in Modern Garage Door Openers
If you’re upgrading or installing a new opener, consider models with enhanced lighting features:
- Motion detection lighting
- LED light strips built into the housing
- Smartphone-controlled lights
- Battery backup for lighting during outages
Some LiftMaster models even feature corner-to-corner LED lighting that covers the entire garage.
How Long Should Your Light Bulb Last?
Here’s a general idea based on bulb type:
- Incandescent: 750–1,000 hours
- Rough service incandescent: 1,500–2,000 hours
- CFL: 6,000–10,000 hours (not ideal for cold garages)
- LED: 15,000–25,000 hours (best performance + efficiency)
Do’s and Don’ts When Choosing a Garage Door Opener Bulb
✅ Do:
