This handmade lamp features a lovely genuine vintage blue mason jar in the very rare large half gallon size. I have added a double bulb fixture and a simple neutral ivory shade. One bulb lights the inside of the vintage jar, and the other the shade. Each light works independently of the other, so you can use both, or light the jar alone. The bulb inside the jar makes for a nice subtle light, or night light. The last photo shows the lamp next to a quart Mason jar for size perspective, the quart size jar for size perspective, the quart is the most commonly used size for Mason Jar lamps (Not Included in Listing). The lamp turns on and off with a switch on the cord and a toggle switch for the top bulb. The lamp measures 15" tall with a 5 foot long cord. All components are UL approved. Light bulbs are not included with this lamp, you can use any bulb up to 40 watts, cfl bulbs are a good choice for their energy savings and cool burning. The photos are taken with a vintage style Edison bulb, if you are interested in a specialty bulb please contact me for a price quote.
