Pære LED Edison 2W 130 lm E27
Useful information
When buying a new LED lightbulb, there are some things you should be aware of. The strength of an LED lightbulb is measured in lumen rather than watt.
15W = 140 lumen
25W = 250 lumen
40W = 470 lumen
60W = 800 lumen
75W = 1050 lumen
100W = 1520 lumen
Furthermore, each lightbulb has an RA or CRI value. This describes the ability of the lightbulb to render colours, and it is measured on a scale from 0-100 CRI, where 100 CRI is the equivalent of natural lighting.
For normal homes, we recommend using a lightbulb with an CRI value of at least 80CRI.
Degrees Kelvin, on the other hand, describe the warmth of the light.
8,500 – 10,000 K = Cold blue
7,000 – 8,500 K = Cold white/blue
4,500 – 7,000 K = Cold white
3,000 – 4,500 K = Neutral white
1,000 – 3,000 K = Warm white
For comparison, candlelight has a degree Kelvin of around 1,500 K, direct sunlight is around 5,500 K, and a blue sky can reach 10,000 K.
