The 'Decimax 120' is a circular recessed light with a large 120mm diameter. Made from rust resistant stainless steel, the contemporary Decimax is very versatile and can be mounted into a number of materials and used in a variety of ways, including as a step light, edging a driveway or patio area, or as a wall light. A hard protective sleeving adds to the durability of the fitting, protecting the lower section of stainless steel which will be fixed into brick, decking or the ground. Approximately 3m of cable is included for ease of installation.

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 color scheme in mind and make sure to buy the bulb with a color temperature to match.


All recessed luminaires must have adequate drainage beneath each fitting to allow water to dispersal, 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. Magic gel should be used in the termination boxes to reduce the risk of water ingress.
Please ensure that your electrician is NIC EIC certified and has done exterior lighting installations before.

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.
