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.
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.
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.
