     Sitra - 240v Anthracite Powder Coated Aluminium Fixed Down Light Wall Light IP44 GX53

The Sitra is a beautifully made wall mounted fixed down light in Germany which uses the GX53 puck style LED lamps. They offer long lamp life and can come in a variety of beam angles to create a unique wall wash effect and look great on stone walls etc. The lamps are available in either warm white 2,700 kelvins or cool white 4,200 kelvins.


Lamp colour ( Kelvins )

The colour of a lamp is defined as a measurement called kelvins. A standard GLS light bulb in your house would be 2,700 kelvins which is in the warm colour spectrum and a lamp with 6,000 kelvins would be at the very cold white spectrum. Getting the right colour temperature of a lamp does matter as the warm colour wavelength helps to soften skin tones and gives a warm soft relaxed feel and at the other end of the scale a 4,000 to 6,000 kelvin lamp colour  would be used in offices or a fast food restaurants to make you feel less comfortable and relaxed and more alert. There’s nothing that can sour your opinion of a compact fluorescent  or LED lamp like buying a 4000K or 5000K bulb when you meant to buy a 2700K bulb, or vice-versa. When you buy a new, energy efficient bulb, keep your application and colour scheme in mind and make sure to buy the bulb with a colour temperature to match. 

       

Light output ( Lumens )

The amount of light that is produced by a lamp is called lumens and the more lumens the lamp has the brighter it will be. Lumens work in conjunction with kelvins and should not be taken in isolation of each other, for example if you had a very warm white lamp at 2,700 kelvins and it produced 300 lumens and you then had another lamp which was a cool white 6,000 kelvins which also produced 300 lumens the cooler lamp colour would always appear brighter to the naked eye than the warmer one this is due to the receptors in the eye that react better to a white light spectrum. Another factor on how bright a light may appear is contrast so if you shine a white 6,000 kelvin light on to a dark wall and a warm 2,700 kelvin lamp on to a white wall the warmer lamp would appear brighter due to the contrast of the material it is focused on. So when choosing a lamp always take in to account the area you want to illuminate and think about Kelvins ( colour ),  Lumens ( brightness) and contrast  ( colour of area ) 

Installation 

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 a IP rating which is explained further in our design ideas section but in simple terms the IP rating is 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 as the weakest point is always cable and transformer joints. All joint must be made 100% water tight and this can be done using heat shrink kits, waterproof junction boxes which are then filled with a resin 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 joint than a low voltage installation but care must be taken with the cable runs.

PRODUCT AFTERCARE

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

TEAK WOOD

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.

ALUMINIUM

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.

FeCSI-Steel

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

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.
