Caverna In-Wall / Step Light - Natural Copper - GU10 - 240v 

The Caverna is an in-wall or step light crafted from durable and elegant Natural Copper, with a rounded cavern like shield. This acts to divert all the light in one direction without glare. Copper will weather and darken naturally once outside, and will eventually develop a Verdigris finish.

The robust black plastic sleeve is supplied to protect the Copper step light and assist with installation. The sleeving should be built into the wall during construction or retrofitted into a drilled out hole. The main part of the step light then pushes into the tube, where it is held firmly in place.

The Caverna is supplied with approx. 3m of  H05RNF cable which gives the option of up to a 6m space between two lights should it be required with only one cable join. Lights can also be installed across a wider area with longer cable length and could cut down the number of cable joins dramatically.

Please note: This fitting must be installed with the mounting sleeve and additional rubber seal. If the sleeving and seal is not used, the Guarantee will be void. Not for use in areas prone to water-logging or flooding.

Step lighting example


Lamp colour ( Kelvins )


The colour of a lamp is defined as a measurement called kelvins. A standard GLS incandescent bulb in the home would be 2,700 kelvins which is in the warm colour spectrum and a lamp with 5,000 kelvins would be at the very cold white spectrum.

Installation 220 – 240v

Choosing the style of a product is only part of the equation you must also think of where that product will be used and how it will be installed. All exterior lighting products on our web site have an IP rating appropriate to each light fitting and its intended application and is therefore fit for purpose. Water ingress is the enemy for outdoor lighting and the products supplied are only as good as the installation. The weakest point is always cable joints. All joints must be made 100% watertight and this can be done using IP68 cable connectors and/or waterproof junction boxes which are then filled with a re-enterable liquid gel mix. All joints where possible should be made above ground for easy access and reduced water ingress. When installing ground buried lights adequate drainage systems should be put in place especially in clay-based soil areas. If possible, use ground surface spike lights rather than a buried light.  Mains 240v cable will have less joints than a low voltage installation but care must be taken with the cable runs. Cabling should be Rubber Butyl and not PVC. PVC leads to capillary action over time especially with UV degradation.

All exterior lights must be installed by a certified NIC EIC electrician and should be signed off by an electrician with Part P certification. There are a selection of waterproof jointing kits and boxes available on this web site.

Using a single RCD for large numbers of 240v fittings is not recommended due to the risk of nuisance tripping. We advise the use of separate RCD protection for each circuit and a maximum of 12 fittings per RCD. Where a garden lighting installation of more than 12 spike mount or recessed lights per circuit is proposed, we suggest the installation of 12v units with transformers, which results in a significantly higher fault tolerance and reliability in the total installation.
