The fitting comes complete with its own wall bracket which enables the light fitting to have a degree of tilt.
The shape of the internal reflector means it throws a symmetrical wide beam of light
and must be angled down to avoid any direct glare or upward light spill.
Care must be taken when installing exterior lighting products especially ground buried lights.. All the products are sold fit for purpose and tested before given an IP rating. More details on IP ratings can be found under design ideas section. The weakest point is generally the installation of the product where adequate drainage has not been made for ground buried lights or poor cable joints have been made which are not 100% water tight and will allow water to penetrate weak joints.. There are a number of waterproof enclosures available on this site along with heat shrink cable joint kits and resin gel packs to fill the junction boxes and make a watertight enclosure. Where possible try and keep all joints and transformers above ground, however if this is not possible there are potted burial kits available.
Lamp colour is determined by the Kelvins and a lamp which is 2,700 kelvins is classed as warm white and is sympathetic to skin tones and warm brickwork. A lamp with a kelvin of 6500 is in the cold blueish white spectrum and works well against a white background and will appear brighter to the naked eye than the warmer colour spectrum.
All lamps have a lumen number and the higher the lumen number the brighter the lamp, however colour of the lamp (kelvins ) also comes in to play here as a whiter lamp at 6,000 kelvins and above would always appear brighter to the naked eye than a warmer colour lamp at the 2,700 kelvins light spectrum even if it has the same lumen output. A halogen 150w R7 lamp that is used in a standard garden security flood light would produce around 2,300 lumens and a 26w compact fluorescent would produce around 1,800 lumens. Placing lights closer to the item to be illuminated is a good way of using a lower lumen lamp rather than trying to flood light a big area.
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.
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.
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
