Check your bulbs before you do anything! I waited until my outdoor project was done and my pergola was built and at night i went to hang the lights and put in the bulbs. Six of them were burnt out already and i had just opened the package. This was supposed to feel like a reveal and it was a ruined project because of the burnt bulbs. Not a happy buyer. 

On a positive note, the bulbs that do work have a warm vintage glow.
