There are three products available in the Nails family which include a floor bollard, a wall light and a tall slim ground spike light. Lighting families are ideal to bring a whole design concept together for your exterior lighting plan. a very clean and simple design with a etched glass insert to help diffuse the light.
The nails is a slim unobtrusive style of fitting which uses a mains G9 capsule lamp.
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.
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
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 their normal 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.
