Which Is Better? LED vs. Incandescent Christmas Lights
Both can look beautiful on a roofline. Here's how they really compare on color, cost, safety and how long they last.
Quick answer: for most homes, LED Christmas lights are the better choice. According to ENERGY STAR, certified LED light strings use about 70% less energy and can last up to 10 times longer than incandescent strands. They also stay much cooler to the touch. Today's warm-white LEDs give the cozy, classic glow people love about incandescent bulbs.
Side-by-side comparison
| Compare | LED | Incandescent |
|---|---|---|
| Energy use | About 70% less (ENERGY STAR certified strings) | Higher |
| Lifespan | Up to 10 times longer | Bulbs burn out more often |
| Heat | Cool to the touch | Bulbs get warm to hot |
| Durability | Plastic or sealed bulbs resist breaking | Glass bulbs can crack or shatter |
| Color | Warm white, pure white and vivid colors | Classic warm glow |
| Upfront cost | Higher | Lower |
Color: can LEDs look warm?
Early LED Christmas lights had a cold, bluish tint, and that's where their bad reputation comes from. Modern warm-white LEDs are a different story. They're made to match the soft, golden glow of a classic incandescent bulb, and on a roofline most people can't tell the difference. If you want something crisper, pure white gives a bright, modern look. Colored LEDs are richer and more saturated than painted incandescent bulbs.
Energy use and your electric bill
Because LEDs use a fraction of the power, a whole roofline can glow all season without a noticeable jump on your bill. It also means more lights can run on one outlet and circuit, which matters for big displays.
Safety
LED bulbs run cool, so there's less heat near dry leaves, wreaths, garland and your home's trim. They're also less likely to break, which means fewer shards of glass in the flower beds after a windy night.
Lifespan and maintenance
Incandescent strands are known for one bulb going out and taking half the strand with it. LEDs last far longer and hold up better season after season, so there's less time on a ladder hunting for the dead bulb.
When incandescent still makes sense
If you have a vintage display you love, or you only decorate for one season, incandescent lights cost less upfront. For lights that go up every year, LEDs usually win over time.
Bulb sizes you'll hear about
- C9 bulbs. Large, classic bulbs. The go-to choice for rooflines and peaks.
- C7 bulbs. A little smaller than C9. Good for windows, railings and smaller homes.
- Mini lights. Small bulbs, perfect for wrapping trees, bushes and garland.

Common questions about LED Christmas lights
Are LED Christmas lights brighter than incandescent?
They can be. LEDs give strong, even light for very little power. Warm-white LEDs are made to look soft and cozy rather than harsh, so they read as bright without glaring.
Do LED Christmas lights use less electricity?
Yes. According to ENERGY STAR, certified LED light strings use about 70% less energy than incandescent strands.
What kind of Christmas lights do professional installers use?
Most professional installers use commercial-grade LED lights, often C9 bulbs on rooflines and mini lights for trees and bushes. Ace uses commercial-grade LEDs on every install.
