Please ensure that you use a PART P, NIC EIC electrical contractor to install your exterior lighting.
All the products are sold and tested fit for purpose and the IP rating is set according to the design and purpose of the luminaire, more details on IP ratings can be found under design ideas section. The weakest point is generally the installation of the product where poor cable joints have been made which are not 100% water tight and will allow for water penetration. There are a number of waterproof enclosures available on this site along with IP68 inline connectors and resin gel packs to fill the junction boxes to make a watertight enclosure. Copper grease should also be used on screws and nuts to stop them binding and ease removal at a later date when a lamp change is required it can also provide a watertight seal. Never use PVC cabling only use Rubber. PVC can lead to capillary action.
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 5,000 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 the tone of the area
and gives a warm soft relaxed feel and ideal for colourful flower beds and rockery areas especially with wooden bark
and at the other end of the scale a 4,000 to 5,000 kelvin lamp colour would be used against a light background such as
white walls or to accentuate grey blueish foliage in shrubs and small trees. 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.
