Home office lighting without the buzzword bingo
Kelvin numbers, bounce light, and one rule that fixes most setups in ten minutes.
One bright key, one soft fill
A window or a desk lamp can be your key. Bounce a second source off a wall for fill. Avoid two harsh LEDs aimed at your face.
Color temperature
Warmer light (2700–3000K) feels calmer for evening work. Cooler (4000–5000K) can feel alert for daytime focus.
