This vintage Lava Lite Midnight Series lava lamp comes in the original box. It was made in 1996 by the original American manufacturer (the first lava lamps were made in England and now all lava lamps produced for the USA market are made in China). The black base lamp with purple lava is style number 490334, the model number is 8409. When put together, total height is 16-1/4 inches. The lamp looks better at night in a dark or semi-dark room - the purple is much brighter, almost neon magenta. The tiny purple bubbles in my photos occurred when I moved the lamp into place for the pictures. They eventually settle back into the larger blobs and the liquid becomes clear again.
The cord and plug are in excellent condition. The cord has a slider or dial type on/off switch. The black painted aluminum lamp base has two minor dings but no scratches or paint loss. The box has minor age discoloration and light storage wear but is intact. The special interior protective box for the bottle is present. I had to purchase a 40 watt appliance bulb to test the lamp and will include it with shipment.
