"ITALIAN CAFE" LIGHTS USE VINTAGE EDISON BULBS TO CREATE GREAT AMBIENCE ON YOUR PATIO: Install Brightech's solar powered pergola lights as a canopy over your porch or gazebo for a retro bistro look and a pleasant party ambience. The Ambience Pros are bright enough to grill and eat, without being overpowering. Enjoy until late: They last 5-6 hours on a full charge, i.e. 6 hours of direct sunlight. Indirect sunlight works too, per reviews, but provides less charge/hour.
