CW vs WW: Cool White or Warm White LED — Which Should You Choose?

When buying LED lights you will often see the options CW (Cool White) and WW (Warm White), and sometimes NW (Neutral White). This Dr. Light guide explains the difference so you can pick the right tone for each room.

Key takeaways

Cool White (CW) is a bright, crisp tone — great for work and utility areas.
Warm White (WW) is a soft, cosy tone — great for relaxing areas.
Neutral White (NW) sits in between and is available on selected models.
Mixing tones across a home is completely normal and often looks best.
