What is the Philips Hue BR30 Bulb?
The Philips Hue BR30, a lot like the Philips Hue GU10, is simply a different version of the normal Philips Hue Light. In this case the Philips Hue BR30 Flood light version of the Philips Hue light bulbs.
The BR30 is one directional (for the most part it only points in direction) unlike the regular bulbs which are omnidirectional (they can light up the whole room). The BR30 is better for large areas that you want to light up (such as a large room, or other large open area).
It is not recommended that you put Philips Hue bulbs outside, however it is possible.
