The amount of light that is produced by a lamp is called lumen's and the more lumen's the lamp has the brighter it will be. Lumens work in conjunction with kelvins and should not be taken in isolation of each other, for example if you had a very warm white lamp at 2,700 kelvins and it produced 300 lumens and you then had another lamp which was a cool white 6,000 kelvins which also produced 300 lumen's the cooler lamp colour would always appear brighter to the naked eye than the warmer one this is due to the receptors in the eye that react better to a white light spectrum. Another factor on how bright a light may appear is contrast so if you shine a white 6,000 kelvin light onto a dark wall and a warm 2,700 kelvin lamp onto a white wall the warmer lamp would appear brighter due to the contrast of the material it is focused on. So when choosing a lamp always take into account the area you want to illuminate and think about Kelvins ( colour ), Lumen's ( brightness) and contrast ( colour of area).
These bollards have an E27 lamp holder and work well with GLS LED E27 base light bulbs. 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 meters and no more than 12 meters apart. The shorter distance would be for garden pathways, Public parks and car parks 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 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 or magic gel. 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.
