It is not necessary to connect the earth wire when the bed light fixture or wall light fixture has a double insulation enclosure. As the light fixture is double insulated all current-carrying parts are protected/surrounded by insulation material in different types of plastic.
If there is no earth wire at the lamp site, then you must choose a lamp that is double-isolated.
If there is an earth wire at the lamp site, then you can choose both a double isolated lamp and a lamp with earth wire connection.
There are several different types of sensors, but the most commonly used sensor types in connection with lighting are either a so-called PIR sensor (Pyroelectric Infrared Sensor) or a Microwave sensor. The first-mentioned sensor type senses when a warm object (human or animal) moves in the sensor’s area. When the sensor is activated the light will turn on for a period that is predetermined (set) or you can decide the interval / set how long you want the lamp to be turned on after the sensor has registered people or animals in the area.
The sensor’s area is stated on the user manual or on the packaging. The microwave sensor sends out microwaves which are thrown back to the sensor (like an echo sounder) when they hit an object that is moving within a given range. When the waves are registered by the sensor the lamp turns on for a period that can also be set to a determined period of time.
This can happen if there is condensation in the lamps. If the condensation drips from the top of the lamp to the light bulb it can cut the circuit-breaker. See our section on remedy for condensation in garden lamps. The lamp might also be connected the wrong way. Make sure that the earth wire is connected to the earth terminal on the lamp, or that the double isolation box is at least 10 cm above the surface of the ground in the tube of the garden lamp.
You must not connect more lamps in series than the fuse box that you connect the lamps to allows. A 10 A fuse can handle a max. load of 2300 Watt. If it is fluorescent light fixtures, it varies how many you can connect depending on the ballast (the electronic or mechanical unit that turns on the fluorescent light) in the lamp. By connecting too many fluorescent light fixtures together you can exceed the circuit-breaker’s maximum load of 0.03 A. It is difficult to say exactly how many of the fluorescent light types in question you can connect together, as several conditions are a factor. When you reach the limit of how many you can connect together then ”the rest” has to be connected to a different circuit-breaker (a different group).
Most of the lamps from the Nordlux outdoor range can be connected in parallel and at the moment that includes lamps in the series Discos outdoor, Phantom, Matrix, Sapphire, Clover, Cayenne, Tofu, Pilar, Figure, Sydney, Agger, Hirtshals, Aalborg 2002, Vejers, Blokhus, Fredensborg, Amalienborg, Phoenix, Venø, Scorpius, Bowler, Arc, Square, Hurricane, Malte, Virum, Iris, Luxembourg, Nibe, Cube, Marine and Skot. This will also be stated in the technical specifications that are found under the lamp description for the product in question.
Coastal areas are harsh on lamps as the high humidity and exposure to salt accelerates corrosion of the materials. Nordlux has a large range of particularly resistant materials designed for exactly these environments. Certain wind conditions can also accelerate corrosion far from the coast. This is the case for coasts with sustained onshore wind from saltwater seas. These are most common in the North Sea and Northwestern Europe, where accelerated corrosion can occur up to 25 kilometres from the coast.
For coastal areas, Nordlux recommends lamps in copper, brass, nickel, corten steel and galvanised steel, and we offer a 15-year guarantee against corrosion.

Condensation is a natural phenomenon which occurs under certain atmospheric conditions. Moist, warm air and cold meet and lead to condensation of water inside the light fixture/glass.
When the water evaporates, it results in rising water vapours which may affect the electrical components – sometimes resulting in the RCD/RCCB disengaging. Condensation is not covered by Nordlux' guarantee, unless it can be demonstrated that a defect in the light fixture caused the penetration of water. If condensation occurs, the following should be checked: Has the light fixture been mounted/installed correctly? – Do the seals shut tight, and are screws and glass fastened sufficiently? – In the case of garden/flowerbed light fixtures, might rising soil moisture in the light fixture tube cause condensation?
This can be remedied by filling the tube with a sealant. Among other things, PU foam is recommended! – Drainage holes must be kept free from impurities. Remember to wipe all parts before the light fixture is put back together!
The majority of Nordlux’s recessed in-ground spotlights can be used for driveways. If the package is marked with a symbol which indicates that the spotlight can take a load of 500kg, it is suitable for a driveway when the spotlight is level with the surface.
Water in in-ground spotlights can have several causes. It must be checked whether the cable lead-in boxes have been tightened sufficiently, so that water cannot penetrate from below. It is also important to ensure that the seals of the light fixture are positioned correctly and that the screws which hold these seals in place are tight and tense enough. If you experience problems with seals and voltage, you should also ensure that the plastic frame is intact

All Nordlux lamps are designed for fastening. You can choose to fasten the lamp in a self-made base, or for most of the lamps you can choose to get a bury base which comes with screws that fit the foot of the Nordlux lamps. If the lamp is buried you must be careful that the connection box/double isolation connector is not under ground level.
The connection box must be placed at least 10 cm above the surface of the ground in the tube. Nordlux does not recommend burial of stainless steel garden lamps.
A twilight switch turns the exterior lights on or off automatically via a light-sensitive element which measures daylight levels. Most twilight switches can be set to a selected degree of darkness, so that the light will switch on when the chosen degree of darkening is reached. Likewise, the switch will turn off the light fixtures when it is bright again. It is important to note that a twilight switch does not contain a motion sensor, and therefore will not respond to movement, but only to the degree of darkness.
At present, Nordlux has no light fixtures with a twilight switch.
