Arrock granite 70 bollard, E27, mains 240v, max.15W


Made from real granite with salt and pepper colouring. A fantastically individual style of bollard light with stainless steel louvre and opal diffuser to throw the light in 360 degree. ECO friendly 15w compact fluorescent lamps can be used or candle LED E27 bulbs. It stands 700mm tall and there is also a smaller 400mm version available. Both can be either directly mounted to a flat concrete surface or with the additional spike available can be mounted into soft earth. Not the cheapest on the market but then how many people do you know with a real exterior granite light fitting.

The E27 base allows you to use a variety of lamps. The lamps are available in different colour options ( kelvin's ) from cool white to warm white. 


Bollard types and spacing


Bollard lights are available in a massive choice of styles, finish and lamp options. You need to think about how the light will be used for example a small garden pathway, the main driveway or to illuminate steps etc.  If you are within 20 km of the coast you should think about using the wooden bollards or marine grade 316 stainless steel. Some bollards have built in LED lamps and they generally offer lower levels of light ( lumen's ) than say a compact fluorescent. Also if the lamp is an integral part of the bollard then it cannot be replaced if it fails in future so you will have to purchase a complete new bollard. There are bollards that use GU10 LED lamps and in this case can be changed for a ECO friendly GU10 LED lamp. The spacing of the bollards will depend on the lamp output, louvre design, height etc but a general rule of thumb would be no less than 3 meters and no more than 12 meters apart. The shorter distance would be for garden pathways and the longer distance for long driveways.


                                                                
                                                                                                                                        

                  

Environmental impact

Care should be taken for the environment and local wildlife to maintain the ecological balance. Insects, bats and other types of wildlife can all be effected by light pollution. The warmer colour spectrum of  2,700 kelvins does not interfere with insects and general wildlife as much as the blue colour spectrum of light around 5,000 kelvins which can disrupt their normal night time activity. This also applies to bats where anti glare light fittings work better as well as reducing the overall light pollution in the area. You must also be mindful of your neighbours and the effect your lighting can have on them. 


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. 

 

 

  


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. When installing ground buried lights adequate drainage systems should be put in place especially in clay based soil areas. Also mains cable should be SWA rubber and not PVC.


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.
