Lava lamps are the perfect combination of modern and minimalist design with the retro look of the original 1960s lava lamps. Lava lamps are an iconic item, now considered a classic in decoration and ambient lighting. The reason for their success is the relaxation caused by the hypnotizing effect of the moving wax bubbles as they go up and down. The lamp works with 1 bulb (included) 30W R39. It is important to know that the first time you use a lava lamp, the wax needs between 3 and 5 hours to heat up and start forming bubbles; after that, the time decreases. The optimal operating temperature is between 21 and 26º C. The lamp's height is 36cm and its diameter is 9cm. Made with aluminum and glass. Inside the bottle is wax, which is heated, changes its state of solidity, and begins to flow in the form of bubbles. Do not touch any part of the lava lamp while it is on or just turned off. The lamp requires very high temperatures to operate. It complies with European regulations.
