Rokit Instructions

Rokit Box Contents

This product comes with six components:

  1. Base Assembly
  2. 3 x 80W R7s Bulbs
  3. Glass Shield and Screw x 2
  4. Allen key
  5. Bottle
  6. Spun Metal Cap

POSITION

  • For indoor use only. Choose a position on a clean, sturdy and horizontal surface.
  • Do not place near sources of heat or cold, such as a heater or air conditioner. The product operates at its best in a room between 20º C / 68º F and 24ºC / 75º F.
  • Keep the cable away from heated surfaces.
  • For best performance we recommend you keep the product away from: sunlight to prevent fading, drafts and cold places to prevent slow operation and freezing, hot places to prevent overheating.
  • Place the base on a stable and flat surface.

ASSEMBLY

This product comes with 8 components:

  1. Avoid handling bulbs with your bare hands, instead use a soft cloth or similar. The oil from hands causes hot spots and may cause the bulb to fail prematurely.
  2. Fit the bulb into the product by pushing one end in and springing it into place between the lampholder contacts. Ensure that each end of the bulb is sitting properly in the lampholder.
  3. Fit the glass shield in position. It is essential that this part is fitted in place before use.
  4. Carefully lift the bottle by the neck and place the bottle onto the heat ring from the front of the product. Ensuring it is vertical and stable.
  5. Fit the spun metal cap in place.

WARM-UP

Warm up takes 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.

OPERATION

  • 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 your 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 the bottle or a lot of very small bubbles.
  • Never move or shake the product when it is in use or still warm, as this causes irreparable clouding.
  • It is normal for the glass to have small air bubbles and moulding scars.
  • REPLACEMENTS

    At the end of its life cycle your product will start to become cloudy, the colors will fade and the lava will not circulate as well as before. This will happen after about 2000 hours of use. Whether your product has reached its end of life or you want a different color combination, visit our website www.mathmos.com for more information on replacement bottle

    If the bulb is burnt out, replace it with a bulb of the same type and wattage. Only use an appropriate bulb as indicated on the label located on the base. For more information on replacement bulbs go to our website www.mathmos.com

    IMPORTANT! Allow your product to cool completely before picking it up or moving it. Once your product has completely cooled, use the supplied Allen key to unscrew and remove the screws located on the sides (keep its parts carefully). Carefully lift the cap. Lift and remove the bottle from the base. Place the spare bottle on the product and see the ‘assembly’ section for assembly instructions.

Rokit FAQs

  1. Q. Where is the Mathmos brand on my Rokit?
    A. The Mathmos branding is on the leg.
  2. Q. I have broken the Rokit glass shield, do you have spares?
    A. Yes. Mathmos lava lamps are designed to last please buy replacement parts here.
  3. Q. Will a Lunar Bottle work on my Rokit?
    A. The Rokit, iO and the Lunar use the same bottles and are interchangeable.
  4. Q. How can I clean my Rokit lava lamp?
    A. The bottle should be cleaned with glass cleaner and a microfibre cloth. Only use a microfibre cloth to clean the aluminium parts. The silicone slots can be cleaned with a damp cloth. Do not use abrasive cleaning products as this can irreparably damage the product.
  5. Q. You don't provide a dimmer with the Rokit?
    A. The Rokit runs best at an ambient temperature between 20 and 25C and under these circumstances will not need a dimmer. Sometimes when the temperature is higher it may be better run the product with the lamp dimmed. Plug-in dimmers suitable for halogen lamps are available and can be used with the product.
  6. Q. Do I need to fit the glass shield?
    A. Yes, this is an integral safety component of the product.
  7. Q. How long should it take for my Rokit lava lamp to warm up?
    A. The Rokit Lava lamp should start working within two to two and a half hours of turning it on. First it 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. As the Rokit use a lower wattage lamp than the iO the lava can perform differently to that model. 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.
  8. Q. I am having trouble changing the bulb.
    A. Ensure that the product is unplugged and cool. At first glance, the bulb looks too long for the lamp holder, however, the contacts are spring loaded. Locate one end of the bulb on the pin and gently push, the other end of the lamp can then be located on the other pin. Refit the glass shield.
  9. Q. How much does the Rokit Weigh?
    A. The Rokit weighs 12 kg.
  10. Q. What size is the Rokit?
    A. The Rokit is 65.5 cm (25.79 inches) high and 25 cm (9.84 inches) in diameter.
  11. Q. I can sometimes see a blue flash of light from the switch. Is it safe?
    A. It is perfectly safe. As the live current makes contact with the other part of the switch it can occasionally create a small blue flash.
  12. Q. Are the halogen lamps that the Rokit uses not banned?
    A. These lamps are currently exempt under the new UK and EU Eco Design regulations.

  4. Q. Why does my lava lamp have specs and bubbles in the glass?
    A. Mathmos lava lamp bottles are manufactured in one of the highest quality automated bottling factories in Britain. Small bubbles are a normal part of this manufacturing process, it is not a fault.
  5. Q. What are the differences in quality between a Mathmos lava lamp and others?
    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.

  7. Q. My lava lamp just has one large bubble sitting at the top of the bottle that does not move?
    A. The lava lamp is overheated. It could have been on too long (more than 8 hours), so please turn it off and allow it too cool. Or it is positioned in a room that is too hot (more than 24 degrees) or next to a heater. Please reposition your lamp.

    A.

    Bottles are now supplied with a lip which runs around the lower part of the bottle, to ensure it will sit straight in the base. When the bottle is placed on the base, it should sit securely, although it will still be possible to move the bottle from side to side and a shadow gap may be visible.

    There are minute variations in bottle and base size over time so it may be that occasionally for some much older products a new bottle does not fit in the base. If your bottle isn't sitting in the base, please contact our customer service team.

  14. Q. What is Mathmos doing about halogen bulb phase out?
    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.

  20. Q. Why can I see bubbles in the lava?
    A. Small bubbles in the lava are normal particularly when you first receive the lamp. As you use this over time the bubbles will reduce.
  21. Q. Why has the liquid in my bottle gone clear?
    A. Over time the dye in the lava liquid will fade, particularly if it is positioned in direct sunlight. If you lamp was bought within warranty and the instructions were followed please contact our customer service team. If your lamp is out of warranty you can buy a new bottle here.

    liquid clear - clear liquid

  22. Q. The liquid level of my lamp is too low. Can I top it up?
    A. No Mathmos lava lamp bottles are sealed units. Do not attempt to take off the cap and on no account top up the liquid. The heat from a lava lamp causes the liquid to expand and topping it up could cause the lamp to be overfilled and put pressure on the glass as the liquids expand. If you are not happy with your bottle buy a new one here.

    liquid low - liquid refill - top up liquid

  23. Q. Why is there wax sticking to the side of the bottle?
    A. If you use the lamp a few times this wax should join the rest of the lava. If this does not happen and your lamp was bought less than a year ago please contact us here. If you lamp is over a year old please buy a replacement bottle here.
  24. Q. Do you offer any colours in addition to what is shown on your website?
    A. No, however we do constantly add new colours so sign up to our mailing list to be notified of new colours as they are released. We do occasionally release short runs of special colours, please sign up to our social channels to be notified.

    bespoke bottles - special bottles - custom bottles - custom colour

  25. Q. Why can I see a metal spring coil floating in my lava lamp bottle?
    A. The metal spring is an essential component of a lava lamp bottle. However it should be sitting at the bottom of the bottle. Run the lamp for several hours and hopefully the spring will settle in its right place.

    metal coil in bottle - metal spring in bottle

  26. Q. Why can I see a foreign object in my new lava lamp bottle?
    A. There should not be anything other than lava and liquid in the bottle. Sometimes you can see darker specs in the lava as it is flowing. Each batch is individually made and these are dye particles that are sometimes present. These often fade over time. If you see anything else in your bottle, please contact customer services here.

    A. Due to electrical safety regulations we are unable to supply lamp holders I’m afraid.
  39. Q. Has the formulation of Mathmos lava lamps changed?

  40. Q. Why does my lava not flow / make lava shapes?
    A.
    Check your bulb is working
    Check you have positioned the lamp away from drafts, air conditioning or a window. Try the lamp in a new position in the room.
    Make sure the room is at least 20 degrees centigrade.
    The lamp will take longer to warm up the first few times; run the lamp for 4-6 hours each time.
    If you have an older base check the correct light source is fitted: see bulb section for the possible bulbs here.
    Check there is a coil at the bottom of the bottle.
  41. Q. What should I do if my lava lamp has been moved while being on and is now cloudy?
    A. Clouding in a bottle which has been moved when it is in use or still warm is irreparable. You can try and run the bottle for a few times to see if this will improve it. If this does not help, you can buy a new bottle here.
  42. Q. How do I fit my halogen bulb?
    A. See instructions here
