Color temperature describes whether white light appears warm, neutral, or cool and is expressed in kelvins (K). For LEDs, the more precise term is Correlated Color Temperature (CCT). CCT is not a measure of brightness. Nordic Lights commonly uses 5000–5700 K for work lights and offers warmer light for demanding conditions such as dust, rain, fog, or snow. Cool white light can support a crisp visual impression in many industrial tasks, while warmer light may improve comfort and visibility in conditions where airborne particles reflect light back toward the operator. The most suitable value depends on the application and environment. Color temperature should be evaluated separately from CRI, operational lumens, and the chosen light pattern.
