The product is cleverly designed so that after fixing the back plate to the wall it simply slots into place and is fixed with two screws, Allen keys provided. See video below.

Designed by Jonathan Coles Studio and made of cast metal in silver, copper or part white Neo Wall is available in 6 lava colour combinations.  Like its sister product Neo, this wall design is low voltage and powered by halogen capsule running cooler than other lava lamps.

Simple Assembly

Neo Wall has a number of features that make it easier to put up than most wall lights. The lead simply hangs down the wall and plugs into a standard socket. No need to hold the whole lamp while fixing it to the wall, attach the back plate first then slot on the lamp. See video above. NB. Wall fixings vary depending on the composition of your wall.

Wall Bosses

Every Neo Wall comes with three wall bosses included. These can be either stuck or screwed to the wall to tidy up the lead. Take the lead straight down the wall, create a shape or just let the lead hang free then just plug into a regular socket.


Neo wall is particularly great in pairs or groups. Take advantage of the 20% discount when you buy more than one.

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.

    A. A different lava formulation giving better lava flow, longer life, clearer liquids and more vivid colours.

    If you 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.
