Cool White vs. Warm White Christmas Lights: What’s the Difference?
Christmas lighting depends on which look you like best
Highlights

Warm white color can vary by company and brand.
Cool white and warm white lights have similar life spans, cost, and ease of installation.
If you’ve ever found yourself contemplating the difference between cool white and warm white Christmas lights, look no further. While both lights are white, they are two completely different shades and can set the tone for your holiday decorating. Let’s review the difference between these options and when to hire a local light installer to create a holiday light design for you.
Cool White vs. Warm White Christmas Lights: Key Differences
The “color temperature” of these lights, measured in Kelvins, varies greatly and can influence how types of Christmas lights appear. Warmer lights have an appearance closer to the golden hues of natural lighting, while cooler lights tend to look less natural but excel at imitating an “icy” look. Energy-efficient LED lights are more customizable, with warmer options closer to sunlight or candles. Cool white and warm white light options give Christmas decorators an important choice to make when buying white lights.
What Are Cool White Christmas Lights?
Cool white lights have become more popular in recent years and are often used on commercial properties to create an icy, wintry holiday look. Here are the pros and cons of using cool white Christmas lights for your decorations.
| Pros | Cons |
|---|---|
| Complement an icy, snowy landscape | May not match older sets of Christmas lights that have a more yellow hue |
| Can appear brighter due to their slight blue color | May appear more commercial if used on a home |
| Easier to match with different brands of lights | Not as popular as warm white |
Best for:
Homeowners who like an icy, wintry look
Blue and silver decor
Outdoor decorating
Commercial properties
Pros of Cool White Lights
Cool white lights look best with wintry decor and may even appear to be brighter at night than warm white lights due to their bluish hue. Another pro of cool white lights is that they are easier to match the color if you use different brands of lights, since cool white stays more consistent from brand to brand.
Cons of Cool White Lights
Cool white lights are not as popular as warm white Christmas lights and tend to be used primarily on commercial buildings. These lights may give your home a more commercial feel if you decide to use them. Also, if you’re hoping to mix in a few older strands of Christmas lights tucked away in storage, they may not match the cool white lights, since older Christmas lights tend to be warm white with a yellow hue.
What Are Warm White Christmas Lights?
When you think of traditional Christmas lights, you’re probably picturing warm white lights. These lights have been used by decorators for years to give off a cozy holiday glow. Here are the pros and cons of decorating with warm white lights.
| Pros | Cons |
|---|---|
| May match older sets of Christmas lights | Warm white color can vary depending on the brand |
| The most popular color of Christmas lights | Will use more energy if not using LED lights |
| Work for indoor and outdoor decorating |
Best for:
Homeowners who love the traditional look of golden Christmas lights
Red and green decor
Indoor decorating
Pros of Warm White Lights
Warm white lights are the quintessential Christmas lights that have been used for years. These lights are best for people who love tradition and decorating with classic Christmas colors of red and green. The warm color of these lights makes homes appear more inviting, and they can be used both indoors or outdoors without appearing too jarring. Plus, if you’re hoping to use a few older strands of incandescent Christmas lights with your new warm white lights, they’re more likely to match in color.
Cons of Warm White Lights
Warm white shades vary and can appear more or less yellow depending on the brand of lights or the installation company. This can make it difficult to match your lights when replacing or adding additional lights.
Additionally, warm white incandescent lights use more energy and will burn out more quickly than LED lights. You can solve this issue by switching to LED warm white lights, which look similar in appearance but are more sustainable and longer-lasting.
Cool White vs. Warm White Christmas Lights
Consider the following features to help you decide between cool white and warm white Christmas lights.
Appearance: Warm White
Appearance is mostly up to your personal taste, but there’s no denying that warm white lights are more popular and preferred by most homeowners who decorate their homes for Christmas. Warm white appears more cozy and inviting, which sets the perfect vibe for homeowners hosting guests at their homes for holiday gatherings.
Sustainability: Tie
As long as you’re using LED lights, there’s no difference in energy usage between warm white and cool white lights. Warm white incandescent lights are less sustainable and use more energy, but you can easily switch to LED warm white lights to solve this problem.
Price: Tie
Price is determined by the design of the LED lights and their extra features, not whether they are warm or cool. LED lights are more expensive at the initial purchase, but make up for it by lasting longer and using less electricity over the years. Expect to pay around $12 to $17 for a basic string of white LED lights, warm or cool. More features, like the ability to change colors with an app or extra-large bulbs, can easily double that price. Especially warm LEDs, like down to 1000 Kelvins, may cost extra because of their rarity.
Lifespan: Tie
While the color of warm LED lights may look more natural, they don’t produce more heat or work harder to create that yellowish tint. It’s a matter of using different materials and coatings when creating the diodes, which doesn’t affect durability. Expect both LED options to last for years with sturdy wiring and proper care. Note that you can replace LED bulbs in string lights if problems arise.
Lumen Rating: Cool
Lumens are a measurement of how much light a light source produces, as measured by the human eye. It’s not related to wattage or other power measurements, just the brightness of the visible light, which makes it useful when comparing multiple kinds of lights.
In this case, cool LED Christmas lights have a slight edge, since cooler color temperatures tend to look sharper and reach farther. This factor may be important if you want a particularly dazzling Christmas display or want to guarantee that people can see it from the road.
Ease of installation: Tie
Once again, warmer white LED lights don’t produce more heat, so there’s little risk in putting them next to dry materials, unlike incandescent lights. All other design aspects of these two color options are largely the same, so installation isn’t a big concern.
Ease of Repair/DIYability: Cool White
While you can easily fix Christmas lights regardless of color, cool white lights stand out because the shade is easier to match. Warm white color varies from brand to brand, and it may be difficult to match the color of replacement lights to your old lights. Cool white tends to stay consistent in color and will be much easier to replace with a matching set.
Bottom Line: Which Is Better?
Cool white and warm light Christmas lights have very few differences other than color. While cool white is more consistent in color from brand to brand, warm white lights more closely match older incandescent Christmas lights that you can still use. Both are good options for your home. Ultimately, it comes down to your personal preference and taste.
