Con Very dim light
180 lumens won't do much good in terms of lighting (for comparison, regular bulbs produce about 800 lumens - the Oort bulb provides less brightness than the typical refrigerator light). This is really only effective as a supplement to an existing lighting solution as mood lighting, and not a regular bulb replacement.
Con Very short range
With a range of only 12m, don't expect to control your lights from far away. The good news is that the bulbs work together in a 'mesh' configuration, meaning that as long as you are within range of one bulb (and the other bulbs are in range of each other as well), you can control all the bulbs.
