Sitra, wall mounted up and down light, silver grey, 2 x GX53 lamps, fluorescent or LED, IP44



Beautifully made in Germany wall mounted garden up / down light with two lamps which are ECO friendly. The SITRA is part of a family of light fittings which also includes a down only light to match the up / down light and is ideal for the lighting designer to keep a consistent theme.
The 2 x LED GX53 lamp will give a wide beam distribution in a warm white and only uses 3w. Each will create it own unique wall wash effect and look great on stone walls etc. The lumen output of a warm white GX53 3w lamp is 250 lumens and will last up to 25000 hours. Also available in a cool white colour temperature.

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 5,000 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 the tone of the area and gives a warm soft relaxed feel and ideal for colourful flower beds and rockery areas especially with wooden bark and at the other end of the scale a 4,000 to 5,000 kelvin lamp colour would be used against a light background such as white walls or to accentuate grey blueish foliage in shrubs and small trees.  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 5,000 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 5,000 kelvin light onto a dark wall and a warm 2,700 kelvin lamp onto 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 into account the area you want to illuminate and think about Kelvins ( colour ),  Lumen's ( brightness) and contrast  ( colour of area ) .


Installation 


All exterior lighting products on our web site have an 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 joints. All joints must be made 100% water tight and this can be done using IP68 inline connectors, waterproof junction boxes which are then filled with a resin or gel mix. All joints where possible should be made above ground for easy access and reduced water ingress. 

All exterior lights must be installed by a certified NIC EIC electrician and should be signed off by an electrician with Part P certification. 

H07RN-F H07 3 Core Rubber Sheathed Mains Cable 1.5mm is recommended but do not use PVC flex cable as this is a poor connection for the cable glands and will lead to capillary action.



Energy efficient lamps

Choosing the right lamp is a combination of 3 main factors, Lumen's, Kelvins and efficiency. Efficiency matters because you want the maximum light output possible ( Lumen's ) from the minimum amounts of watts consumed. The latest LED lamps will reduce energy bills with no loss of light output and helps the environment too.
