Cool-white icicles Christmas lights on a house
Icicle lights hang in staggered lengths from the gutter so the house looks frosted. Cool white gives a winter, ice-blue feel.

Cool-white icicles: what the sources say
- The Department of Energy describes a cool-white color as usually 5000K to 6500K.1
- OSHA’s ladder standard says that when portable ladders are used for access to an upper landing surface, the side rails shall extend at least 3 feet above it.2
- Utah State University Extension advises pointing lamp sockets down when possible to avoid moisture buildup.3
Verdict. It suits white or gray siding and snowy yards where the icy blue-white tone matches the winter scene; on red brick or cedar it looks clinical and clashes with warm interior lights seen through the windows.
