A. A different lava formulation giving better lava flow, longer life, clearer liquids and more vivid colours. The metal parts are of a thicker, higher grade metal allowing us to hand polish them to a high shine. Our bulbs are directional taking the heat away from the base and directing the light into the lava. We have a higher standard of safety and build quality audited by a number of different bodies. We provide a comprehensive range of spare parts unlike other throw away products. We have 56 years of British manufacturing excellence to draw on.

A. Lava lamps should start working within an hour to an hour and a half of turning them on. First they will form stalagmite shapes, then they will start to form lava lamp shapes.  Please note, new bottles will take longer to heat up (up to three hours), but the heating time will decrease after several uses.

If your lava lamp does not warm up in this time it may be positioned in the wrong place or the room may be too cold. Lava lamps should be positioned away from drafts and air conditioning. The room should be at least 20 degrees centigrade.

A. Don’t worry whilst some halogen bulbs are being phased out for lighting purposes Mathmos uses halogen bulbs primarily to heat its lava lamps rather than to light them; so the use of halogen bulbs in our lava lamps is part of a special purpose exemption under current regulations. We have large stocks of these special purpose bulbs and we also have an ongoing supply. We also have alternative ways of powering our iconic lamps should there be further changes to the regulations in the future.
