It's tough to distinguish different types of "white" light, especially when experiencing a sensory overload at holiday-decorated stores. Here's a quick debriefing of cool white, warm white, and champagne white, so you can get busy decorating your house the way you imagine.
From left to right:
Commercial Cool Clear LED Wide Angle Christmas Lights ($19/50 LEDs) – Cool white lights on a white wire have a slightly blue tint and are a great lighting option if you want a sharp, bright, icy look to your tree or house.
Vickerman Warm White LED Miniature Christmas Light String Set ($22/70 LEDs) – Offered on green wire, warm white lights shine a softer, incandescent, and yellowy light for a more traditional, warmer look.
Champagne White Standard C7 LED Christmas Lights ($13/25 LEDs) – These champagne colored LED lights emit a peachy-yellow light. The bigger, strawberry-shaped LED lights are a decorative shift away from the common mini bulbs.
