Bulb LED 5W (410lm) is a smart three-step light source that can be mounted in your lamp and dim the light using the existing installation. Using the lamp switch, the bulb allows you to dim the light to three levels by pressing multiple times.
Level 1: Full strength
Level 2: 50% strength
Level 3: 25% strength
The three-step bulb works the same way in a pendant where the switch is on the wall.
The bulb has a colour rendering of 2700K, which means that what you get is a warm, white light. The bulb has a full strength of 410 lumen – the equivalent of the light you know from a 40W incandescent bulb.

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 RA, where 100 RA is the equivalent of natural lighting.
For normal homes, we recommend using a lightbulb with an RA value of at least 80RA.
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.
