Today I received from amazon these very affordable color changing LED bulbs that are controlled with an app on my iPhone. For $28 a bulb I figured what the hell. These are connected via bluetooth, but they also sell a wifi version for $35, I don't need to be able to control them when I'm away from home so I went with the cheaper bluetooth version. I installed them in the spotlights in my bedroom. First of all let me say I'm surprised at how well they work at this price. I figured they would work like crap and be sent back tomorrow. Anyway, my question to you guys is this: what are the best colors for putting you in different moods? I want to make some color settings but don't know which to use. What color is relaxing and will help me sleep? (they're dimmable). Which color is good for meditation? Which color is good for boning? I don't even know where to start with these bulbs but they're really cool!
