Color temperature is measured in Kelvin (K) and describes the appearance of light emitted by a source. Lower numbers (2700K-3000K) produce warm, yellowish light similar to traditional incandescent bulbs. Higher numbers (5000K-6500K) produce cool, bluish-white light that resembles daylight.
5000K falls in the "daylight white" or "natural white" range. It's characterized by:
For park lighting applications, 5000K offers several advantages: enhanced visibility for safety and security, better color recognition for surveillance systems, and a modern, clean aesthetic that many municipalities prefer for public spaces. However, it's not universally ideal—some communities prioritize ambiance and wildlife protection over maximum visibility.
"Exterior lighting typically ranges from 3000K to 5000K. The choice depends on balancing visibility, safety, and security needs. Cooler color temperatures like 5000K improve alertness and are preferred for areas requiring high visibility and security camera performance." [5]
