It's quite simple really. By itself, the luc bulb is just a regular LED power-saving light bulb, that shines in bright white color only. However, if you add the luc Bridge to it, you instantly bring additional colors, mobile control and other smart features to your existing luc bulb.
If you wish to control the bulbs directly you can also purchase the luc Remote, however it only offers a limited control range and no smart features. One Bridge allows for the pairing of up to 16 bulbs, which can be controlled on your mobile device (you are not limited to a single Bridge pairing to the app). Similarly, one luc Remote can directly control up to 16 bulbs as well.
