How to Light a Christmas Tree and Mantel Without Fighting Your Chandel

Written by Rick Kovac, COO of Golden Lighting

The takeaway: A Christmas tree looks magical when it's the brightest thing in the room and its light matches the rest of the house. Match the color of the tree lights to your fixtures, then dim the room lights so the tree can shine.

Key takeaways:

A common holiday lighting clash is cool-white LED tree lights in a room lit by warm 2700K–3000K fixtures. Check the color temperature on the box.
Pick one star of the room. When the tree is lit, dim the chandelier and the ceiling lights well down.
A pair of sconces flanking the mantel frames it; a single sconce centered above it doesn't.
Keep the tree at least 3 feet from the fireplace, heat vents and candles.

You put up the tree, string the lights, plug them in and step back. Something looks off. The tree glows a bright, icy white while the chandelier above the dining table and the lamps around the room glow gold. The two light colors fight, and the room looks like two rooms.

It's one of the easiest holiday lighting problems to avoid once you know what to look for.

Match the color, not just the brightness

Light color is measured in kelvins (K). Lower numbers are warmer and more golden; higher numbers are cooler and bluer. Most homes are lit at 2700K–3000K. Many LED light strings are sold as "cool white" or "pure white," which usually sit well above the warm range of home fixtures, and even "warm white" means different things to different makers.

Color temperature scale from 1800K candlelight to 5000K cool daylight, with the 2700K to 3000K band for living and dining rooms marked as the place to match tree lights and fixtures.

Read the box. Look for a kelvin number, not just "warm" or "soft." Aim for 2700K–3000K to match typical home fixtures.
Test before you string. Plug a strand in next to a lit lamp. If the strand looks blue or grey next to the lamp, it will look that way on the tree.
Don't mix strands on one tree. Two "warm white" strands from different brands can look noticeably different side by side.
Match the mantel and the porch too. Garland lights, window candles and porch strings should all sit in the same warm range.

Our rule: one color of white per room. Your tree lights and your chandelier should look like they came from the same place.

Pick one star for the room

Lighting designers plan every scene around one brightest place, with everything else stepping down from it. During the holidays, that place is the tree. If the overhead lights are at full brightness, the tree just looks like another lit object.

Dim the chandelier and the ceiling lights well down when the tree is on. Your eye reads dimmed light as brighter than it measures, so a chandelier at 25% output still looks about half as bright. The room won't go dark.
Keep some light on the walls. A room lit only by the tree feels like a cave with a bright spot. A pair of sconces or a lit picture on another wall keeps the room comfortable.
Turn off cool-white task lights in the same view, such as under-cabinet lights in an open kitchen, or switch them to a warmer setting if they have one.

The mantel

The mantel is the other holiday focal point, and how you light it matters.

Flank it with a pair of sconces. Single sconces belong in pairs, one on each side of the mirror or art above the mantel, never one centered above it. Mount decorative sconces about 60–72 inches off the floor.
Graze stone, wash plaster. If the fireplace surround is stone or brick, light from close to the wall rakes across it and shows the texture. On smooth plaster or drywall, a soft, even wash looks better. Grazing smooth walls just shows every trowel mark.
Keep greenery clear of heat. Garland and stockings shouldn't touch bulbs, candles or the firebox opening.

The safety part

The U.S. Fire Administration gives the core rules. Keep the tree at least 3 feet from fireplaces, radiators, space heaters, candles and vents. Water a live tree every day. Inspect every light strand before it goes up and throw away any with damaged wires. And don't connect more strands end to end than the manufacturer allows.
