DuoMarka - 240v Copper GU10 IP67 Recessed Light 2 Windows 180 Degree Of Light
The DuoMarka is an elegant recessed light suitable for illuminating steps and outlining other areas in the garden, mounted
in the ground, walls or decking. It is made from high quality, natural copper, which creates a traditional appearance,
blending in with surroundings.
This fitting is available in Stainless Steel and Brass too in both 12v and 240v along with the 12v version in Copper.
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.
The DuoMarka has two conical sections on one side of the top of the fitting, which allows a 180º diffusion of light through a clear lens, without glare. The slightly domed surface makes this the ideal shape for mounting on decking, a patio or any other areas where a walk over facility is required. The front bezel is threaded, and attaches to a copper body by screwing together with no external screws or fixings which results in a neater overall finish. This also means no tools are required to change the GU10 lamp (LED recommended).
The robust black plastic sleeve is supplied to protect the copper 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 light then pushes into the tube, where it is held firmly in place, leaving only the streamline front dome on show.
Please note that Copper will darken as a result of a chemical reaction between copper and oxygen causing Oxidation and this process begins when copper is exposed to the oxygen in the atmosphere, rain, condensation and humidity. It will gradually dull with a tan look and without treatment can turn to dark grey and blue known as patina associated with tarnished copper. Many people love this look. If you keep the fittings cleaned regularly this will slow the process down.
COPPER & BRASS
Both brass and copper are extremely durable materials, with brass being a combination of copper and zinc, meaning neither
can rust or corrode. Over time brass will subtly weather and naturally change to a darker colour which will blend in with
the garden surroundings. Copper also naturally changes colour quite dramatically, often resulting in a brown or ‘verdigris’
effect, again to blend in with the outdoor surroundings. This is because copper reacts with atmospheric oxygen. Although
some people may prefer a pristine, shiny copper finish, the oxide layer in fact prevents corrosion and simply adds to the
character of natural copper creating a traditional, ‘olde worlde’ appearance. If a new copper finish is preferred, a layer
of lacquer can prevent / slow down the weathering process.
240v IN-GROUND LIGHTS
240v fittings can be affected by damp conditions, typically when located outdoors. When a fitting is located outside in the cold air combined with the heat produced by the lamp inside, it is inevitable that condensation will occur, just as it does on bedroom windows in the home. If too much condensation is produced, this could result in the fitting tripping, especially in these types of fittings where a drainage hole is not possible. To combat this, we include silica gel with all Duomarka 240v in-ground lights to soak up any excess moisture – these should not be removed but replaced periodically and fittings checked. If any water is sitting in the fitting, this should be tipped out and the fitting safely dried out. Condensation can be more prominent when the fitting has been opened on a damp day, as the damp air will then be trapped inside when re-sealed. Therefore it is recommended that any maintenance, including changing bulbs, is performed on a dry day. An additional practice is to apply Lithium Grease to the bulb holder / bulb which acts as an additional seal to prevent tripping. Although this prevents tripping, the fittings will still need to be checked and dried out should water sit inside the fitting. For extra protection, the Duomarka fitting can also be filled with Wiska Gel (electrical insulation).

Although each of our light fittings come with a warranty, it is also important to take care for your product after installation. The outdoor environment can be harsh with very warm and hot conditions as well as extremely cold, wet, and windy conditions and more especially in coastal areas where the salt air is more concentrated causing corrosion. By neglecting to care for your product may void any warranties. Below is information on caring for the different type of products we sell.
COPPER, BRASS & BRONZE
Brass and Bronzes are families of copper-based alloys and mainly copper and zinc. Bronzes are mainly copper along with alloying elements such as tin, aluminium, silicon, or beryllium. Brass generally has a bright gold appearance dependent upon the percentage of copper yields, the higher the percentage the rosier the tone will be, and more zinc will make it appear silvery. Brass has higher malleability than bronze or zinc and is ideal for resisting corrosion including galvanic corrosion from saltwater. Copper products start off with a shiny orange appearance and once installed copper weathers naturally to a lovely blue-green colour or patina over time. In arid climates, the colour change is usually to a nut brown. The colour change is the result of surface oxidation caused mainly by moisture and corrosive elements in the atmosphere. Unlike rust oxidation, the copper patina is a protective barrier that retards further corrosion, to maintain copper’s long life. They are ideal for coastal areas and to keep them looking pristine we recommend cleaning copper surfaces periodically with a solution of salt and vinegar to remove any excess deposits. Simply dissolve salt in vinegar, then use a soft cloth to apply the liquid solution to the surface of the fitting then buff until you see the copper begin to shine. Rinse and dry. The ‘Brasso’ product is a metal polish designed to remove deposits from brass, copper, chrome,and stainless steel. WD 40 is also useful for cleaning brass too and wipe off with soapy water.
316L & 316 STAINLESS STEEL
The highest grade of Stainless Steel we use is 316L Marine Grade Stainless Steel which is a low carbon version of 316 Stainless Steel (which is why it has L after the 316). These grades of Stainless Steel are popular for use in Coastal areas due to the materials immunity from boundary carbide precipitation (sensitisation). However, 316 Stainless Steel contains more carbon and although is still corrosion resistant it does still need care to remove the depositsthat build up on the surface or the corrosion will eventually start to build up on the surface. We sell more 316 than 316L products on this website. The elements of 316L and 316 Stainless Steel are Carbon, Manganese, Phosphorous, Sulphur, Silicon, Chromium, Nickel, Molybdenum, Nitrogen, and Iron. The only difference is that 316L has 0.03 max % of Carbon and 316 has 0.8 max % of carbon. To maintain the shiny clean surface of 316L and 316 Stainless Steel we recommend the use of Stainless-Steel cleaning products or a solution of lemon juice and baking powder and wiped off with soapy water.
304 STAINLESS STEEL
304 Stainless Steel is made up of Carbon, Manganese, Phosphorous, Sulphur, Silicon, Chromium, Nickel, Nitrogen, and Iron. There is no presence of Molybdenum the anti-corrosive element and this metal has a high carbon content too. Therefore, we would not recommend this metal used in coastal areas. Again, it can be cleaned with Stainless Steel cleaning products or a solution of lemon juice and baking powder and wiped off with soapy water. In addition, we would suggest using an anti-corrosive spray such as ACF-50 which forms a clear film onto the surface of the fittings and adds protection to the surface for up to sixmonths. We sell this on our website. https://www.exteriorlightsuk.co.uk/product/acf-50-anti-corrosion-formula
201 STAINLESS STEEL
201 Stainless Steel is made up of Carbon, Manganese, Phosphorous, Sulphur, Silicon, Chromium, Nickel, Nitrogen,and Iron. It contains half the nickel and more manganese and nitrogen than the other popular steels. It is also the least expensive of the steel metals we sell. This mid-range product is prone to corrosion such as salt water and not suitable for coastal areas. Again, it can be cleaned with Stainless Steel cleaning products or a solution of lemon juice and baking powder. In addition, we would suggest using an anti-corrosive spray such as ACF-50 which forms a clear film onto the surface of the fittings and adds protection to the surface for up to six months. We sell this on our website. https://www.exteriorlightsuk.co.uk/product/acf-50-anti-corrosion-formula
Our Teak lighting use timber from a sustainable source, organically oiled during production to enhance and protect the grain. The teak bollards for example are made from a natural raw material which reacts to temperature changes and will naturally release sap or may sweat inside the protective packaging. So, please don’t be alarmed if you notice this when you unpack the bollards from their packaging. Once installed, they will weather naturally in the garden, although further oil, stain or varnish treatments are recommended periodically to preserve the beauty of these products. This should also help prevent the build-up of mildewand drying out from the sun. Teak Sealer and Teak oil can be purchased from many timber and DIY stores. They are suitable for all areas including coastal areas.
Many of our products are made from aluminium which is formed of aluminium oxide in an ore called bauxite. Alumina and bauxite are the two main raw materials in the aluminium making process. Aluminium is obtained by the electrolysis of alumina which extracts pure aluminium metal from alumina. Aluminium will not rust however it does suffer from oxidation and is prone to corrosion. We would not recommend Aluminium products in coastal areas. To maintain the surface of the product you can clean with a solution of vinegar and water and rinse with soapy water. Again, our ACF-50 anti-corrosive spray will provide a clear protective coating to the surface of the fittings and can offer up to six months protection. https://www.exteriorlightsuk.co.uk/product/acf-50-anti-corrosion-formula
POWDER COATED FINISHES
Many of our coloured finished products have been powder coated onto aluminium. This is a technique to apply decorative and protective finishes to aluminium through a process that electrostatically charges the powder consisting of a mixture of finely milled resin and pigment, spraying it on to the aluminium surface as a baking process. Although they look effective, please bear in mind that the powder is a paint and in coastal areas the paint can peel and expose the aluminium to corrosion. Therefore, we would not recommend powder coated aluminium fittings in coastal areas. To clean the surface simply use soapy water and a soft cloth and do not use anything abrasive as this will damage the finish. Again, our ACF-50 anti-corrosive spray will provide a clear protective coating to the surface of the fittings and can offer up to six months protection. https://www.exteriorlightsuk.co.uk/product/acf-50-anti-corrosion-formula
ANODISED PAINT FINISH
Anodised coloured paint finishes give a lustre shiny finish to the surface of aluminium fittings and this is done by dipping the aluminium component into an acid electrolyte bath and applying an electric current to the liquid usinga cathode. This causes oxygen ions within the aluminium to be released, which then combine with the aluminium atoms on the surface of the component to create the anodic oxide finish. This process gives the metal surface a porous structure, which can then be coloured with dyes and sealed afterwards. The advantage of the anodised finish is that it is not applied on the surface of the metal, instead, it is integrated with the aluminium substrate, which means it does not peel or chip like paint. The beauty of anodising is that it does not come off and it should protect the aluminium depending upon the thickness for at least 5 years and therefore reduce corrosion occurring. If used in coastal areas, we would recommend they are cleaned regularly with soapy water. Again, our ACF-50 anti-corrosive spray will provide a clear protective coating to the surface of the fittings and can offer up to six monthsprotection. https://www.exteriorlightsuk.co.uk/product/acf-50-anti-corrosion-formula
POLYCARBONATE (PC) –PLASTIC
Polycarbonate is a durable thermoplastic material with high impact resistance. It is quite light in weight and used primarily for Amenity style light fittings. It is fine for use in all areas including the coast. It should be cleaned periodically with warm soapy water to remove any deposits that have accumulated over time.
The element Iron (Fe) used in conjunction with steel alloys is put together to produce a product that eliminates the need for painting, and which forms a stable rust-like appearance after several years’ exposure to the weather. This product is used in some of our bollards under our ‘Rustic Bollard’ Category. They are very heavy and robust fittings. The surface oxidation of weathering steel takes approximately six months. When first purchased some residue rust colour from the manufactured product may be visible and will wash away with the elements of the weather. Over time they will naturally give a rust effect appearance and you will be able to touch them without any rust residue staining. An example of this is shown on our website for the ‘Rusty Slot’ fitting. They are ideal for all areas including the coast.
Granite is a coarse-grained igneous rock composed mostly of quartz, alkali feldspar and plagioclase. It is a hard semi-porous rock which is resistant to heat and cold. Ideal for any area, however salt deposits in coastal areas will accumulate onto the surface of the rock so it is advisable to clean the surface with warm soapy water periodically. Do not use anything abrasive.
