After returning three solar lights purchased to give our renovated deck some nice night light, I ordered these based on good reviews.  These lights provide a bright downcast light that is perfect for summer nights.  The package states that the solar energy will power for 6 hours but I have sound they stay lit for 8-10 easily.  I ordered two more sets.  

Pros: So easy to install - two screws.  
Cons: The second set was yellow lighting but the company was fast in the exchange.
