My favorite part of my outdoor living is these lights. They turn on every night without me having to think about them. The panels are South-facing, so I can easily get 6 hours of light after a sunny day. The bulbs are big, I love how long the string is to the panel so I can have it a little further away, and I just clipped the panel to the roof of my balcony. Extremely easy! There's only 10 bulbs per string, so I needed 3, but I would buy these over and over again.
