UPDATE: 
One doesn't work without fussing with it due to flimsy wiring in the entire socket. These are NOT replaceable bulbs!! They're wired to the socket. You can unscrew them to find them connected with very flimsy wires. 
Def NOT WORTH THE MONEY! We've used these 3 times for about 15 mins each time now there's a problem with one. Shop elsewhere for a better price!
These are very cute and perfect for outdoor table. However they're lightweight to the point of blowing off the table in a higher wind so I'll be bringing them in when we have high winds and or storms. They give off a nice warm glow that's nice for ambiance but not for dining out doors by. I would buy them again or maybe a 2nd set for deck.
