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.
As a general rule the steps are marked every other tread as per the illustration below. The other reason is the surface you are illuminating is very dark and tends to suck the light in. A cool white lamp is required on very dark colours where a warm white lamp works better on sandstone and light grey finishes.
