Using a single RCD for large numbers of 240v fittings is not recommended due to the risk of nuisance tripping. We advise the use of separate RCD protection for each circuit and a maximum of 12 fittings per RCD. Where a garden lighting installation of more than 12 spike mount or recessed lights per circuit is proposed, we suggest the installation of 12v units with transformers, which results in a significantly higher fault tolerance and reliability in the total installation.
Bollard lights are available in a variety 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, Copper, Iron, Brass or Marine Grade 316 Stainless Steel. Some bollards have built in LED modules which generally offer lower levels of light (lumens) than a standard LED GU10 lamp. Also, it is likely the LED module is a sealed unit and an integral part of the bollard which cannot be replaced if it fails meaning you will have to purchase a complete new bollard. There are bollards that use GU10 LED lamps and E27 base LED lamps. The spacing of bollards will depend on the type of bollard, louvre design, height and lamp output 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.
The colour of a lamp is defined as a measurement called kelvins. A standard GLS incandescent bulb in the home would be 2,700 kelvins which is in the warm colour spectrum and a lamp with 5,000 kelvins would be at the very cold white spectrum.
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 an IP rating 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. The weakest point is always cable joints. All joints must be made 100% watertight and this can be done using IP68 cable connectors and/or waterproof junction boxes which are then filled with a re-enterable liquid gel 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 joints than a low voltage installation but care must be taken with the cable runs. Cabling should be Rubber Butyl and not PVC. PVC leads to capillary action over time especially with UV degradation.
All exterior lights must be installed by a certified NIC EIC electrician and should be signed off by an electrician with Part P certification. There are a selection of waterproof jointing kits and boxes available on this web site.
