Retro lava lamp with an original glass design. The black wax creates an elegant atmosphere. The soothing rise and fall of the bubbles produces wonderful light effects and a cozy ambiance (not suitable as the sole lighting for a room). This mood light is a focal point in your living room or a trendy table lamp in a youth room. The light body is made of sturdy glass, and the lamp is operated via a switch on the cord. The light bulb generates heat, which initiates the lava process, taking a certain amount of time (more than 2 hours). Caution: never shake or turn the warm lava lamp, as this can disturb the process and lead to discoloration of the liquid.
