Sitra wall, fixed down only wall light, anthracite, 1 x GX53, fluorescent or LED lamp, IP44



Beautifully made in Germany wall mounted fixed down light with two lamps options available which are both very ECO friendly. The SITRA is part of a family of light fittings which also includes a up and down light to match the fixed down light and is ideal for the lighting designer to keep a consistent theme.

The fluorescent GX53 lamp will give a wide beam distribution in a warm white and only uses 9w. The 3 x 1.4w LED GX53 lamp has a cooler lamp at 3250k and produces a narrower beam angle as shown in the location image. Each will create it own 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‚Äôs 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 ( Lumen's )

The amount of light that is produced by a lamp is called lumen's and the more lumen's the lamp has the brighter it will be. Lumen's 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 lumen's and you then had another lamp which was a cool white 6,000 kelvins which also produced 300 lumen's 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 ),  Lumen's ( 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.

Energy efficient lamps

Choosing the right lamp is a combination of 3 main factors, Lumen's, Kelvins and efficiency. There are other factors but not so relevant for exterior lighting products.  Efficiency matters because you want the maximum light out put possible ( Lumen's ) from the minimum amounts of watts consumed. The latest LED technology and compact fluorescent lamps are amongst the most efficient you can buy today. An example would be to change a mains halogen GU10 35w lamp to a ECO friendly GU10 5w LED lamp. The same be done by changing the older GLS light bulb for a compact fluorescent lamp. Reduced energy bills with no loss of light output helps the environment and reduce your energy bills.

IP Rating

All the luminaries on our web site have been specifically designed fit for purpose and assigned a relevant IP rating which denotes the amount of protection that is required from water and dust. More information on IP ratings can be found in the design ideas section on this web site.
