How Bright Should Exterior Garage Lights Be?
Choosing exterior lights for your garage is not as easy as it sounds. There are several factors, such as style, size, placement, color temperature, etc. that you will need to consider. You also need to know how bright exterior garage lights should be.
The brightness of exterior garage lights must find the right balance between safety & security on one hand, and ambiance & curb appeal on the other.
Garage lights are a part of the complete outdoor lighting plan for your home. Make sure that they are in harmony with other parts, such as porch lights, driveway lights, landscape lights, etc.
Moreover, you must be mindful of your neighborhood and surrounding environment too. Your exterior garage lights should not be so bright that they become a nuisance for your neighbors or result in light pollution.
How Many Lumens Do I Need for Outdoor Garage Lighting?
The lumens that you need for outdoor garage lighting will depend on the number of garage doors and the light placement. You can use the chart below as a guideline to get you started but feel free to improvise and personalize.
| Door Configuration | Light Configuration | Lumens Per Light Bulb | Total Lumens |
| One Car Single Door | 1 centered above the door | 800 lm | 800 lm |
| One Car Single Door | 1 on each side of the door | 450 lm X 2 | 900 lm |
| Two Car Single Door | 2 above the door, evenly spaced | 800 lm X 2 | 1600 lm |
| Two Car Single Door | 1 on each side of the door + 1 centered above the door | 550 lm X 3 | 1650 lm |
| Two Car Two Doors | 2 above the door, evenly spaced | 800 lm X 2 | 1600 lm |
| Two Car Two Doors | 1 on each side of the door + 1 in between the doors at the same level | 550 lm X 3 | 1350 lm |
NOTE: Total lumens requirement is recommended to ensure an average brightness of at least 20 lumens per sq. ft. for the first 4 feet adjacent to the garage door.
How Many Watts for Outdoor Garage Lights?
When it comes to light bulbs, you need to be aware of the following specifications (always listed on the packaging/product literature)
- Watt is a measure of energy consumption
- Lumen is a measure of the light output
- Color Temperature is an indication of the hue of the white light
Sometimes Watts is equated to Lumens. This is only partially true. A higher-watt light bulb has a higher lumen, but only for the same type of bulb. There are four different types of light bulbs to choose from:
- Incandescent Light Source (ILS)
- Compact Fluorescent Light (CFL)
- Light-emitting diode (LED)
- Halogen Light Bulbs
The Lumen to Watt ratio is very different for each type. For the best lights for your garage exterior, determine the lumen requirement for each one of the exterior garage lights. The wattage of the lightbulbs depends on the type of light bulb you choose to install.

Why Use LED Lights Outdoors?
LED light bulbs have become extremely popular in recent years because they give the highest lumen-to-watt ratio. In essence, you are getting more light and spending less money.
LED light bulbs have several additional benefits too:
- Long lifespan (can last as long as 50,000 hours). That is a whopping 17 years if they are on for 8 hours a day, every day.
- LED bulbs with adjustable CCT allow you to switch from cool white to warm white
- Models with built-in dusk-to-dawn features are readily available
- Can work with motion sensor technology
LED light bulbs are expensive but pay for themselves in savings in the long run.
Frequently Asked Questions
What’s the ideal color temperature for exterior garage lights?
Choose 3000K–4000K for a warm, welcoming glow. Go higher (5000K) for a cooler, more security-focused appearance.
Can LED bulbs work with motion sensors?
Yes, most LED bulbs are compatible with motion sensors and even offer energy-saving features like dusk-to-dawn functionality.
How can I avoid light pollution with my garage lights?
Use shielded fixtures and ensure lights are angled downward. Choose the appropriate brightness to illuminate your space without disturbing neighbors.
Are LED bulbs worth the cost for outdoor garage lighting?
Absolutely! Though pricier upfront, LED bulbs last longer, consume less energy, and offer customizable features, saving money over time.
