When purchasing a LED bulb you should pay attention to the amount of Lumen and Kelvin it produces. Lumen tells you the light output. The more lumen, the more light the LED bulb gives. Kelvin gives you the color of the light. The smaller the degrees Kelvin, the warmer the light of the LED.
| Color temperature in Kelvin (K) | Description light color |
| 2000 - 2500K | yellowish white |
| 2500 - 2900K | extra-warm white |
| 2900 - 3300K | warm white |
| 3300 - 5000K | neutral white |
| > 5000K | cold white |
