These 16-inch lava lamps, with a blue liquid and green wax, are a wonderful decorative light to add to your home, providing a clear focal point and mesmerising glow in any room they are placed in thanks to their silver shining bases and cap. Be transported back in time as you add some instant retro nostalgia to any room in your house with these lamps, which are well suited to a bedroom, living space or office area. These lava lamps feature wax that slowly moves around the lamp to create a relaxing and soothing ambient mood light. Watch the different-sized formations of melted wax collide, flow, and split apart as they ooze their way up and down the glass globe. The mains operated lava lamps come with a SES E14 R39 screw-in bulb which provides the warming glow within the tube.
