### ⭐⭐ 







  
  
    Ehhh....
  

*by R***Z on Reviewed in the United States on October 6, 2017*

I have used viavolt before... the color of these bulbs were supposed to be 6500k. And the bulbs do not have any indication of the K value. The value was good. As you can see it's a warm light not a bright light.

### ⭐⭐⭐⭐⭐
