20W LED Dusk to Dawn Bollard - Vandal Resistant. Dusk to Dawn - Illuminated Bollard with Photocell
These robust, professional LED bollard lights with Photocell are a revolution in bollard lighting. Comes with a replaceable 20W Warm White LED corn lamp supplied with each bollard with an incredibly high lumen output. The Ledifice is ideal as amenity lighting for larger, commerical or public areas where a high level of light is required without the need to turn the fittings on and off manually, such as car parks, lakes, golf courses etc. Instant bright light is generated when darkness is detected (dusk) and automatically turns off again when the photocell detects light (dawn). The LEDifice photocell bollard is an ideal and effective way to reduce energy bills yet add security.
3 different heights are available: 600mm, 800mm or 1000mm, 2 colour options: garden green or graphite black powder coated finishes, and 2 styles of head (domed of flat pillar designs). The green fittings are 70mm longer and this is reflected in the drop down menu above.
Each bollard is supplied complete with a removable internal mounting base
as standard, which can be attached to expanding achor bolts, root mounting J-Bolts, or mounted onto any flat surface. Alternatively,
a Professional Root Mounting System is available.
A clear, UV stop polycarbonate diffuser
surrounds the centre section of the head (spares available) and silver aluminium internal louvres add character to the bollard
as well as acting as anti-glare shields / protecting the LED bulb. The head and 2.5mm thick extruded aluminium cylinder
of the bollard light are created from heavy duty die-cast aluminium, and all external screws are allen
(socket) type made from stainless steel, resulting in a completely rustproof and non-corrosive product.
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 driveways.
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.
