## Product's reviews:
- Perfect! - Best price after searching the internet, and shipping was super fast. Order to received in 4 days!
- Good - as expected and needed
- Rab x17xfu35w - I definitely will be using this fixture again! Sooooo many options in one fixture. From adjustable color temperature to brightness/wattage adjustability to self contained photocell bypass. MRO SUPPLY did what that said and has the fixture in my hand in under 3 business days. I will without a doubt be using this company again
- Made of quality material - The sensor is very well made with quality material. Directions were straight forward and easy to follow. Works well so far.
After I purchased it I found out it only works in temperatures greater than-4F.
