First and foremost all new external electrical works must be installed by a PART P registered electrical contractor. The contractor must supply you with full certification once the work is completed. For mains 240v supply SWA ( steel wired armour ) cable is highly recommended and rubber round double insulated cable can be used for low voltage installations ( NOT PVC ). Each supply should also be on its own RCD. Cable should be buried to a safe depth to avoid any unnecessary risk due to garden forks or spades. Equally as important and probably the weakest link in any exterior cable run is the joining of cables. Each joint will need to be 100% water tight and this can be achieved by the use of Magic Gel poured in to junction boxes once the termination is complete or heat shrink kits as per FIG 1 and FIG 2 below. Where possible try and keep all low voltage transformers and joint boxes above ground, this will reduce the risk of water ingress.

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 a fast food restaurants to make you feel less comfortable and relaxed and 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.
