1.No crakling and noise.I bought this bulb last month,cause the CFL making noise，they are good replacement of CFL for my ceiling fans in bedroom.ONE THING I need to maintain is that a peaceful environment is important for me cause I am easy to be awaked up,no crakling and noise,this is the first pro.
2.Easily controlled.As I mentioned above, I use it in my bedroom,and everday back home from heave work,it is the most relaxable time to lie down on bed and watch movie by pad or reading,when feel sleepy I can easily said ” turn off the light.” Alexa will close it for me.Of course,I had download the app that the instruction book mentioned.
3.Tone the color casually.Winter is coming,and it is really cold if u work deep into the night,it differs from writing on a bed table and turn the light to a brighter,daylight white,when watch TV u can turn to the warmer light,this multicolored function is useful!
1.Heavier than CFL or Halogen bulbs.It is a important factor that u need to consider when the lamp base is not solid enough,but usually it work well.
