Cirrus 45 bollard, with opal diffuser - Teak - mains 240v - E27, 45cm

Cirrus Teak bollard lights use timber from a sustainable source, organically oiled during production to enhance and protect the grain. They will weather naturally in the garden; further oil, stain or varnish treatments may be applied by the user. Teak bollard lights may be bolted to paving and slabs or to an optional ground-mount which can be installed in concrete prior to electrical installation. An optional galvanised ground spike is available for instalation in planting and lawn areas. The diffuser is made of opal glass to hide the shape and all metal parts are 316 grade stainless steel. For added security, Cirrus and Nimbus models feature concealed allen screw fixngs for the top cap assembly: Stratus feature fixings concealed under the lower angled louvre. Elipta wooden bollard lights are 45cm high and available in 240V E27(ES) format to accept a compact fluorecent lamp upto 20 watts for driveway and similar applications where regular use requires and energy saving,long life source; lower power lamps may be used for softer ambient lighting around garden paths, decking and terraces.(Order lamps separately).


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 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.

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 at fast food restaurants to make you feel less comfortable and relaxed and feel more alert. There’s 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 ( 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 

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.
