Zone black bollard, IP65, 20W compact fluorescent.


The Zone black is a high quality professional bollard suitable for commercial or domestic use for lighting pathways and driveways. The clear lens has an internal stack louvre design to help push light down on the pathway for greater illumination. A 20 w compact fluorescent lamp is very bright and energy efficient. The bollard is available in two colour options to suit your environment. It stands at 900mm high. Easy clean contemporary design.

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, 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 can not be replaced if it fails in future so you will have to purchase a complete new bollard. There are bollards that use GU10 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 mtrs and no more than 12 mtrs apart. The shorter distance would be for garden pathways and the longer distance is for long drive ways.
                                     
                                       

You have a choice of lamps which can be a standard GLS, compact fluorescent ECO halogen or LED E27.  The LED lamp is the most ECO friendly and will help reduce your energy bills. With a LED lamp installed you can then link all the bollards on to a dusk to dawn sensor system

GLS to LED comparison 




Lamp colour ( Kelvin's )

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 a fast food restaurants to make you feel less comfortable and relaxed and more alert. There‚Äôs 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 ( 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 6,000 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 6,000 kelvin light on to a dark wall and a warm 2,700 kelvin lamp on to 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 in to account the area you want to illuminate and think about Kelvins ( colour ),  Lumen's ( 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 joint 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 electrical contractor and all cable joints must be 100% watertight. There are a selection of waterproof jointing kits and boxes available on this web site.


Light levels ( LUX )

Light levels are measured in something called LUX. Put simply LUX is a measurement of light falling on a given surface area. For example an average LUX of 200 would be needed for an outdoor tennis court for recreational purposes and a side street  walkway would have an average of 5 LUX. To calculate lux levels you need a very good calculator or computer as there is a number of factors that need to be taken in to account. 



Average levels of illuminance in Lux

Sunny June day 80000 Lux
Bad light stopped play at Lords 1000 Lux
A well lit office 500 Lux
Main road lighting 15 Lux
A residential side street 5 Lux
A clear moonlit night 0.2 Lux


Environmental impact

Care should be taken for the environment and local wildlife to maintain the ecological balance. Insects, bats, 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 theirnormal night time activity. This also applies to bats where a anti glare light fittings works better as well as reducing the overall light pollution in the area. You must also be mindful of your neighbors and the effect your lighting can have on them and shining a 500w tungsten halogen flood light in to their windows at night will cause them distress. 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. Some light fittings also have a anti glare shield fitted to reduce light pollution.
