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


The Arrock is a beautiful natural sandstone 700mm tall bollard light which also has a smaller 400mm tall bollard to compliment it. Natural stone bollards are individual and of a very high standard and who else do you know that has natural stone light fittings? There is also a 3 tier louvre system held by 4 stainless steel shafts and an opal diffuser to scatter light over a wide area. They can be mounted directly to a level hard surface or spiked into soft ground. ECO friendly when used with the energy efficient compact fluorescent lamp.  

The E27 base allows you to use a variety of lamps from the standard GLS lamp to a compact fluorescent and E27 screw base LED lamp. The lamps are available in different colour options ( kelvin's ) from cool white to warm white.

Bollard types and spacing

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. 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.



                                                                        
                                   
                                 

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 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 6,000 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 ( 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 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 ),  Lumens ( brightness) and contrast  (colour of area).


                        

          

             

Installation 

Please check the specification for dimensions before purchasing

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 joints. All joints 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 or magic gel. 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.


All exterior lights must be installed by a certified NIC EIC electrician and should be signed off by an electrician with Part P certification. all cable joints must be 100% watertight. There are a selection of waterproof jointing kits and boxes available on this web site.
