By Jonathan Coles Studio

Working closely with Mathmos lighting designer Jonathan Coles and his team have developed the only wall mounted lava lamp availble.


Cast Metal

Neo is made of solid precision cast metal. Whilst they are complex moulding designs it is straightforward to assemble see video.


Unique Formulation

As with all Mathmos’ lava lamps the bottle is made in Britain and filled by hand in our factory in Dorset with Mathmos’ unique lava lamp formula. Over 50 years of experience and expertise ensures that Mathmos lava flows better, is clearer and lasts longer.


Unique Shape

Neo’s unique sweeping back plate and wall fixing has been optically designed ensuring that it both frames and reflects the lava and looks good from any angle.


Low Voltage

Neo lava lamp is low voltage and powered by a 20w long lasting halogen capsule bulb, included. The built in reflector ensures that heat and light are directed towards the lava and away from the metal.


Shatter Proof Glass

Neo’s Mathmos branded bottle has a coating of shatter proof glass ensuring that should the worst happen and the bottle falls and breaks the glass will be held together.


Great service & Simple returns

  4. M4 Screw x 1
  5. M2.5 Allen key x 1

NOTE: Different wall materials require different types of fittings. Always choose screws and plugs that are suited to the material. If in doubt please use a professional installer

  1. Place the wall mounting plate on a suitable flat surfaced wall. Make sure that the plate can be placed flat against the wall before mounting. Ensure the plate is vertically mounted.
  2. Secure in place with 4 suitable screws through the holes on the back plate. (fixing screws not supplied)
  3. Ensure the cable is fed correctly through the wall cover as shown. Slot the base & wall cover assembly on to the wall mounting plate by hooking the lugs in to the three keyholes.
  4. Check the assembly is hooked on to the wall mounting plate, then secure to the plate by pressing in and turning the screw in the stem of the product using the larger M4 Allen key provided. Ensure the screw is tightened enough so that the assembly cannot be lifted off the wall plate.
  5. Once secure, place the long arm piece on top of the bottle and firmly push in place. Align the Mathmos logo to be facing forward. Carefully place the bottle with the arm piece into the lower cup and line up with the screw hole in the rear of the lower cup.
  6. Insert the screw provided and tighten with the smaller M2.5 Allen key provided.
  7. Slide the correct plug inset (EU or UK) on to the switching power adapter until it clicks.
  8. Plug the switching adaptor provided in to the cable DC socket. Plug the product in and turn it on.


Between 1-3 hours depending on the surrounding temperature. Stalagmite shapes may form during the warm up process, these will then melt and the lava will begin to flow. It is normal for the glass to have small air bubbles and moulding scars.


Your Mathmos product will operate best after it has been used four or five times. For the first few times you may see small air bubbles in the lava. Please note the heating time will decrease after several uses.

Please do not leave the product on for more than six hours a day or allow it to overheat; this will prolong the life of the product. Overheating will shorten the life of the product; if it is overheating there will be either only one large bubble at the top of bottle or a lot of very small bubbles.

Never move or shake the lamp when it is in use or still warm, as this causes irreparable clouding.


When your product has ended its like it will begin to go cloudy, the colours may fade and it will not move as well as it once did. This will happen after approximately 2000 hours in operation. Whether your product has ended its life or when you wish to have an alternative colour combination, visit our website at www.mathmos.com for more information on a replacement bottle or full product. Please note we do not refill bottles. Please on no account open the secure cap and add liquids.

If the bulb blows, please replace it with one of the same type and wattage. Only fit the correct bulb, as stated in the label in the base. Visit our website at www.mathmos.com for more information on replacement bulbs.

IMPORTANT! Always allow the product to cool down completely prior to handling. Do not attempt to move the product until fully cooled.

Once your product has completely cooled, use the Allen key provided to unscrew and remove the back screw out (keep these components safe). Carefully, holding the bottle and arm piece, lift and remove the bottle and arm piece from the base. Carefully take the arm piece off the bottle and place it onto the bottle you would like to use. Now refer to ‘set up’ for instructions on how to assemble.
