I was very happy with the lamps because they were brighter than the original and was a little less power.  I have been using it to to give extra light to an "air plant" and it has had a baby and is thriving!

    Working as intended
  

*by R***T on Reviewed in the United States on January 4, 2018*

Working as intended.  I didn't want really bright lights outside for the driveway, just something to light it up when walking in/out.  They kinda felt loose when installing, but the fixtures were really old, and these worked anyway.  I'm using these in a couple old outdoor motion security lights.  old enough the screw holding the light fixture shut was rusted enough I couldn't open one of them.  Anyway, lights work.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Very Good
  

*by B***2 on Reviewed in the United States on May 4, 2018*

Very Good and glad I ordered the correct size. It took alittle bit looking at the inside of the light fixture that is my outside back door light. Just a suggestion make sure to get the right size. =)
