    They are not the advertised length, won't work in ...
  

*by M***R on Reviewed in the United States on August 3, 2017*

They are not the advertised length, won't work in my RV fixtures! Measures 39-40mm, not 30mm. Will return and try something else.

### ⭐⭐ 2.0 out of 5 stars







  
  
    Great LEDs but they are not dimmable!
  

*by N***N on Reviewed in the United States on August 16, 2016*

Let me start by saying these lights were very satisfying on all my circuits with standard switches.  These were brighter than my conventional bulbs and the light was very natural.Unfortunately these lights are not dimmable, as the add would leave you to believe, and will not provide enough light to find your keys on the circuits with installed dimmers.If these weren't advertised with the dimmable function, they would have received 5 stars.
