Lamp colour ( Kelvins )

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.



Light output ( Lumen's )

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 lumen's and a 26w compact fluorescent would produce around 1,800 lumen's. 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.

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 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 neighbours 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. 


Installation

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.
