Power Supply
Too much for one power supply

This is how it works: The power that the mains adapter has to supply is calculated by adding the individual power ratings (watts) of the intended LED lighting bars and then adding a further min. 10% reserve. The correct mains adapter is then the next larger model. Always allow for a minimum 10% power reserve in order not to overload the mains adapter! (Our calculator takes this into account automatically!)
For the avoidance of any misunderstandings: The mains adapters themselves do not consume 30, 75 or 150W of power! But they are capable of delivering this power! Power consumption depends only on the connected LEDs and the efficiency of the mains adapter! In standby (i.e. when the power supply unit is only plugged into the socket, not connected to LEDs or in operation) the consumption is close to zero.
The cable length for the eco+ and PRO² LED bars is 150cm. In order to extend the cables of the LED bars (150cm), which may be too short (to the installation site of the control unit), I recommend the extension cable by the metre with the solder connectors.
For the aquaLUMix, powerBEAM and multiBEAM products, the cable length is 250cm and should not be extended.
A maximum cable length should always be kept as short as possible. There is a purely physical reason for this: the longer the cable, the higher the voltage drop, the less efficient the lighting. In addition, long cables behave like an antenna; the susceptibility to interference increases massively with the length of the cables. More than 3 m should therefore be avoided if possible.
The cable length of the power supply units is approx. 50cm on the input and output side.
While our LED lights have been on the market since 2013, there have also been occasional complaints. This can never be completely avoided, even with the greatest quality efforts.
Unusual, however, are those (only approx. 0.1% of all orders) in which LED strips already showed partial or complete failures after a relatively short operating time of only a few weeks and months. As a result, these defective LED strips were replaced by us, but unfortunately this only provided a short-term remedy and a similar error pattern was soon apparent. Here the assumption was obvious that overvoltage in the network of the customers was the reason for the failure of the LED lighting. We have therefore examined this topic more closely.
Observe overvoltage protection.
Even if you immediately think of a thunderstorm and lightning strike, overvoltage damage to the LED lighting usually has other, less conspicuous and insidious causes.
A lightning strike leads to a short-term overvoltage and to immediate failure and irrevocable defect of the lighting. Cause and effect are immediately and clearly recognisable. But there is also the long-term overvoltage. This initially goes unnoticed, but considerably impairs the service life of the LED lighting until visible damage and progressive failure occur after just a few weeks and months.
It is already sufficient if fluorescent tubes are operated in the same circuit with conventional ballasts (e.g. another older aquarium lighting) or electric motors (e.g. in vacuum cleaners, drills, etc.). This results in voltage peaks in the nano- or microsecond range, i.e. short-term increases in the mains voltage caused by switching operations in the electrical circuit or electrostatic discharges. For a short time, up to 10,000 volts are released into the line, only for fractions of a second, but this is sufficient to irreparably damage LED modules, electrical components or power supply units. Even power failures in the environment indirectly cause considerable overvoltages when the power is restored and all possible consumers suddenly resume operation at the same time.
How such an event affects the mains in your home and consequently the LED lighting depends on the type of installation and the protective circuits installed by the electrician. If you experience a massive failure of the LED lighting within a few weeks or months, it is in all probability not the quality of the LED lighting, but external influences. A mains filter with overvoltage protection should be installed on the affected supply line. Our LED lights can reach the value of a computer or television set, so you should protect them at least equally against overvoltage. Damage to the LED lighting caused by overvoltage is expressly not covered by the warranty. This is why we recommend the EMZ 504 broadband mains filter with overvoltage protection in the event of an unclean mains supply and/or overvoltage problems, or it can be seen preventively as a kind of "insurance".
No, because 12V is not really 12V. A stabilised DC mains adapter is necessary for LEDs. That means it must output a voltage of 12V DC. An ordinary 12V transformer for halogen bulbs is unsuitable here. The consequences of using one of these could be no light, flickering or even damage.
