Frequently asked questions
- What does a 5000 K bulb look like in everyday terms?
- 5000 K is 'daylight white' — a cool, neutral white light similar to overcast daylight. The Celsius equivalent isn't meaningful for lighting; color temperature uses Kelvin by convention.
- Can Kelvin be negative?
- No. The Kelvin scale starts at absolute zero, so any valid temperature is zero or positive. Any negative Kelvin value indicates an input error.
