The face plate is crafted from durable solid brass with a rustic bronze finish, which blends in well with outdoor surroundings, especially in areas with a more traditional theme. A hard protective sleeving and a long 5m cable results in an easy installation process with fewer unwanted cable joins. The sleeving also adds to the durability of the fitting, further protecting the lower section of aluminium which can be mounted into brick (driveway or wall), decking or the ground. Cut out- 87mm

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 coulour 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.


All recessed luminaries must have adequate drainage beneath each fitting to allow water to disperse, especially in clay based soil beds. All cable joint must be 100% watertight and there a number or waterproof transformer boxes and heat shrink cable joint kits on our web site to choose from. We would advise that all connections and transformer be kept above ground where possible as the weakest link in any exterior garden electrical installation is joining cables together. Please ensure that your electrician is NIC EIC certified and has done exterior lighting installations before. Also ensure that all rubber gaskets are clean and dry before screwing down the front glass and bezel for a water tight seal.

Environmental impact

Care should be taken for the environment and local wildlife to maintain the ecological balance. Insects, bats, wildlife can all be effected by  light pollution. The warmer colour spectrum of  ( 2,700 Kelvins ) does not interfere with insects and general wildlife as much as the blue colour spectrum of light around 6,000 kelvins which can disrupt their normal night time activity. This also applies to bats where a anti glare light fittings works better as well as reducing the overall light pollution in the area. You must also be mindful of your neighbors and the effect your lighting can have on them and shining a 500w tungsten halogen flood light in to their windows at night will cause them distress. Try to keep the light in a downward position and local to the items you want to illuminate and even if you want to illuminate tall trees it can be done in a sympathetic way by placing a ground buried or surface spike flood light directly under the trees to illuminate the canopy. Some light fittings also have a anti glare shield fitted to reduce light pollution.
