Guide 02 · Light color
Lower Kelvin looks amber and cozy. Higher Kelvin looks whiter and bluer. It has nothing to do with how much light you get — that's lumens, and it's a separate number entirely.
The ranges, and where they belong
- 2200–2700K — candlelight to soft white. Best for exposed Edison bulbs, bedrooms, living rooms, and warm vintage interiors.
- 3000–3500K — warm neutral. A good all-around choice for kitchens, dining rooms, and cleaner modern interiors.
- 4000–4100K — cool white. Useful in bathrooms, offices, and task areas that need more contrast.
- 5000K and up — daylight. Made for workshops and detail work. It feels harsh in a room meant to be cozy.
Theo's quick pick
Exposed vintage bulb? Start at 2200–2700K. Everyday lamp? Start at 2700–3000K. For truer fabric, paint, and wood colors, look for CRI 90 or higher.
Remember
Kelvin controls color. Lumens control brightness. Match Kelvin across every bulb in the same room, or the light will look mismatched no matter how good the fixture is.
