The Domitech ZBulb is a fully-dimmable, instant-on LED screw-in light bulb that provides comfortable warm white illumination (2700K), luminance equivalent to a 60-watt incandescent bulb. It is controllable and via normal wall switch and Z-Wave wireless as well. It is using only nine (9) watts of energy, ZBulb is estimated to save approximately 140 EU throughout its average lifespan.
The ZBulb can be used even in two-wire electrical systems where an installation of a standard Z-Wave switch or dimmer will fail. As with all Z-Wave products ZBulb acts as Z-Wave repeater and gives users the convenience of wirelessly controlling lighting from a Z-Wave hub or controller.
It is different from other smartphone controlled LED lights. It can be controlled via your smart device, even after it has been turned off by the normal wall switch. The way this works is that the bulb recognises "Off-On-Off-On" on the wall switch as a "toggle". That means you can control your lighting and adjust its brightness, without worrying about whether it has been turned on/off from the wall switch. The bulb can also be take part on defined home automation scenes. Furthermore ZBulb is able to memorize the last dim status before shut-off.
