The Obelisk is a robust, contemporary 670mm aluminium bollard in stylish graphite black. It instantly enhances and decoratively illuminates an outdoor space wherever it is mounted. The light itself is directed downwards from the top of the cut out centre section, resulting in the inner rectangular space being filled with light with a down light effect. The E27 bulb holder is protected by a clear, glass lens which diffuses light evenly.

RUNNING COSTS: In London there is approximately 4,300 hours of darkness per year, therefore base on the UK average of £0.14 per kWh, the Obelisk Dusk to Dawn Path Light costs as little as £3.01 PER YEAR to run when a 5W LED Bulb is used. Not only this but the lamp will also last up to 30,000 hours (over 5 years), whereas a standard incandescent commonly lasts for only 1000 hours.

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.






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 joints than a low voltage installation but care must be taken with the cable runs.


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.


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 6,000 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. Try to keep the light in a downward position and local to the items you want to illuminate and even if you want to illuminate tall trees it can be done in a sympathetic way by placing a ground buried or surface spike flood light directly under the trees to illuminate the canopy.
