Astro the original lava lamp: Silver

• How do I fit my halogen bulb?

  Halogen bulbs are very delicate. Please find instructions relevant to your lamp here.

• How long should it take for my lava lamp to warm up?

  Most lava lamps should start working within one hour to an hour and a half from being switched on. First, they will form stalagmite shapes before the liquid lava formations. Please note that new bottles may take longer to heat up when new (up to three hours), but the time taken is expected to decrease after several uses.

• Can I buy Bayonet fitting bulbs for my 1960s Astro lamp?

  Yes. We had these specially made to ensure our 60s lamps can still be enjoyed, see here.

• How do I care for my limited-edition Astro bottle?

  The coating on this bottle is very delicate; please take great care. Avoid rotating the bottle on the base as this can cause scratches.

• Where can I buy replacement parts for my Mathmos lava lamp?

  We offer a range of replacement parts for many current and recent models, including bottles, bulbs, bases, caps, and other small parts.

  Mathmos lava lamps are designed to last, with replacement parts available for many models. If you cannot find the part you need, please contact our customer service team.

• Can I exchange a replacement bottle that does not fit my lava lamp?

  If your replacement bottle does not fit your lamp, please contact our customer service team with your order number and details of your lamp. Subject to our Returns Policy, we can advise on exchange options.

• Why is there a metal spring or coil in my lava lamp bottle?

  The metal spring at the bottom of your lava lamp bottle is an essential part of the lamp and helps the lava flow correctly. If the spring becomes dislodged, run the lamp for up to six hours to allow it to settle back into place. This may need to be repeated if the spring does not settle on the first attempt.

• What makes a Mathmos lava lamp different from other lava lamps?

  Mathmos has been manufacturing high quality lava lamps in Britain since 1963. Our lamps feature a unique lava formulation developed to deliver superior flow, longer life, clearer liquid and more vivid colours. We also offer a comprehensive range of spare parts to help keep your lamp performing at its best for years to come. Every Mathmos lava lamp is designed to meet the highest safety standards and undergoes regular independent testing to ensure exceptional quality.

• Why is my lava lamp forming stalagmite shapes?

  Stalagmite shapes are a normal part of the lava lamp warming up process. As the lamp heats up, these shapes will gradually melt and transform into the flowing lava effect. Once the lamp has reached its optimum operating temperature, the lava should begin to flow normally.

• Why does my lava lamp look a different colour from the photos?

  Mathmos lava lamp bottles are handcrafted, so slight variations in colour can occur. More commonly, the appearance of a lava lamp can vary depending on room lighting and screen display settings. Our product photos are taken to represent the colours as accurately as possible, but colours may appear different under different lighting conditions. For more information on how lighting can affect the appearance of your lava lamp, please see our blog article The Appearance of Colour.

• What is Mathmos doing about the halogen bulb phase-out?

  Mathmos continues to use compliant halogen bulbs to heat and light its lava lamps, despite the phase-out of some halogen bulbs for general lighting applications. We are also exploring alternative technologies for future lava lamp designs should regulations change further. Our commitment is to keep Mathmos lava lamps in use for as long as possible by continuing to offer spare parts, replacement bulbs and ongoing support wherever possible.

• How long does a Mathmos lava lamp bottle or bulb last?

  Mathmos lava lamp bottles typically provide around 2,000 hours of operation, although many customers enjoy their bottles for much longer. The lifespan of a bulb can vary depending on usage and handling. Bulbs purchased directly from Mathmos are covered by a one year guarantee. Replacement bottles and bulbs are available on our website for many current and recent models.

• How long can I leave my lamp switched on?

  Most Mathmos lava lamps can be used for up to six hours at a time. Exceptions include the Candle range, which should be used for no more than 4 hours, and the Saturn Giant lava lamp, which can be used for up to 12 hours.

• Where is the Mathmos brand on my lava lamp?

  The location of the Mathmos logo can vary by model. It may be found on the base, cap, or label on the cord, and in most cases, it is etched onto the bottle.

• My bulb has stopped working. What should I do?

  Lava lamp bulbs are delicate and typically last around 2,000 hours of use. If your bulb has stopped working, first check the fuse in your plug and ensure the bulb is correctly fitted. If your lamp was supplied with a spare bulb, we recommend trying this as well.

  All Mathmos bulbs are covered by a 1-year guarantee. If all bulbs supplied with your lamp have failed within this period, please contact our customer service team for support.

• Are lava lamps dangerous?

  No, Mathmos lava lamps are safe and designed to meet applicable safety standards. All Mathmos lamps undergo regular testing by independent bodies.

  Lava lamps are designed to generate heat, which is essential for creating the flowing lava effect. During use, the bottle and metal parts can become hot, so always place your lamp on a stable surface and follow the instructions provided.

  For best performance and longevity, use the correct bulb and do not exceed the recommended operating times.
