3-step dimmable, what exactly does that mean? The biggest advantage is that you can adjust the light intensity without using a dimmer. You can use your wall switch to vary between three different light intensities: 100% light intensity, 50% light intensity and 7% light intensity. You can switch between the three settings by first switching the lamp on, then briefly switching it off and on again. When you switch the switch slowly, you will switch the lamp on or off at your set setting. The lamp also has a memory function. Do you already have a pendant lamp in your home and would you like to equip it with a 3-step dimmable function? Then take a look at the 3-step dimmable E27 light bulbs.
