I found a fantastic bulb in MiHome (regular version) that only required 20 tiles to illuminate a whole room. People have stated in the comments that the remote control does not have the ability to adjust diffused light, which explains why everything is functional. Long presses produce dispersed light, while short presses produce the primary source of illumination. I have been wanting this lamp for a very long time, and now that I have it, I am content with the fact that I still need ;)
