|Colour/Finish:||Powder Coated Green blends well in lawns|
|Construction:||Front bezel is attached to tubular aluminium body. 1m cable via rear entry cable gland|
|Lamp Type:||MR16 20w or 50w halogen lamps or MR16 warm white L.E.D. lamps include 3w or 5w; 50,000 life and low energy consumption make them a popular option|
|Installation:||The plastic sleeve is built into the wall during construction or retrofitted into a hole cut with a coring bit: the light pushes into the tube, where it is held firmly in place by an o-ring. Connect input cable to cable from transformer using T9962 cable joint or T9963 cable splice kit.|
Light output ( Lumens )
The amount of light that is produced by a lamp is called lumens and the more lumens the lamp has the brighter it will be. Lumens work in conjunction with kelvins and should not be taken in isolation of each other, for example if you had a very warm white lamp at 2,700 kelvins and it produced 300 lumens and you then had another lamp which was a cool white 5,000 kelvins which also produced 300 lumens the cooler lamp colour would always appear brighter to the naked eye than the warmer one this is due to the receptors in the eye that react better to a white light spectrum. Another factor on how bright a light may appear is contrast so if you shine a white 5,000 kelvin light onto a dark wall and a warm 2,700 kelvin lamp onto a white wall the warmer lamp would appear brighter due to the contrast of the material it is focused on. So when choosing a lamp always take into account the area you want to illuminate and think about Kelvins ( colour ), Lumens ( brightness) and contrast ( colour of area ) .
All exterior lighting products on our website have an 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 joints. All joints must be made 100% water tight and this can be done using IP68 inline connectors, waterproof junction boxes which are then filled with a resin or gel 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. Also mains cable should be SWA rubber and not PVC.
H05RN-F 2 Core Rubber Cable (12V)
What we would point out is that if your fittings are installed in a clay based soil that the fittings have sufficient drainage underneath such as a bed of shingle approximately 100mm deep. This will ensure that no water logging can take place and sufficient drainage has been made to allow water to run away from the fittings. Secondly, the cable joints must be 100% watertight as this is the weakest point of any in ground installation. IP68 Inline connectors would be ideal and your electrician should have ensured this is in place along with all junction boxes being watertight too using resin packs or gel. Lastly, check the rubber gasket on the screw bezel to ensure that it has no grit or dirt that can allow moisture into the fitting and using copper grease around the inside of the bezel to screw the top to the fitting and this will also provide a water tight seal but try not to over tighten the bezel either.
If the electrician has used Rubber armoured cabling and followed these steps you should have no trouble with your fittings. If he has used PVC cable then in time the connections will allow capillary action to occur and draw in moisture. PVC is a big no no for buried light installations and finally your installation should be signed off by a Part P qualified electrician and he should provide you with a full report of his wiring installation. Therefore, if you need to check anything in the future you will have that information to hand.
