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 or 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 cannot be replaced if it fails in future so you will have to purchase a complete new bollard. There are bollards that use GU10 LED 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 meters and no more than 12 meters apart. The shorter distance would be for garden pathways and the longer distance for long driveways.
Light output ( Lumens )
The amount of light that is produced by a lamp is called lumens and the more lumens 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 lumens 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 ), Lumens ( brightness) and contrast (colour of area).
Lamp colour ( Kelvins )
The colour of a lamp is defined as a measurement called kelvins. A standard GLS light bulb in your house would be 2,700 kelvins
which is in the warm colour spectrum and a lamp with 6,000 kelvins would be at the very cold white spectrum. Getting
the right colour temperature of a lamp does matter as the warm colour wavelength helps to soften skin tones and gives
a warm soft relaxed feel and at the other end of the scale a 4,000 to 6,000 kelvin lamp colour would be used in
offices or at fast food restaurants to make you feel less comfortable and relaxed and feel more alert. There’s nothing
that can sour your opinion of a compact fluorescent or LED lamp like buying a 4000K or 5000K bulb when you meant
to buy a 2700K bulb, or vice-versa. When you buy a new, energy efficient bulb, keep your application and colour scheme
in mind and make sure to buy the bulb with a colour temperature to match.
