LED lighting is characterized by low power consumption, high-quality light and the ability to change the colors of the lamps. This makes it perfect for bathrooms , kitchens and corridors - both as an aesthetic addition and as the main lighting . Most often, however , LED strips are used to illuminate places shrouded in shadow, such as countertops under cabinets or deep shelves. While installing such lights usually does not cause any problems, selecting the appropriate power supply may raise doubts. That's why we advise which model will work best.

Selection of power supplies for LED installations
Do all LED strips require power supplies? This is necessary due to the principle of operation of LED power supplies. The light is produced by a semiconductor made of silicon. It requires direct current to power it. The strength of the radiation depends on the voltage, but it should be a maximum of several dozen volts.
Meanwhile, 230V alternating current is present in the socket. But which power supply should I order to obtain the appropriate output parameters? Much depends on where the LED lighting is installed. There are also two types of power supply devices - some of them produce 12V, the other - 24V. What is the difference between them?
What is the difference between 12V and 24V LED power supply?
LED strips are currently being produced 
powered by 12V and 24V. What is worth noting is that both models consume the same amount of electricity. However, changing the voltage causes a shift in the chromaticity coordinates. Therefore, diodes powered by higher voltage will appear brighter.
However, it is worth remembering about the voltage drop in the case of long LED strips. Above five meters, it is advisable to use an additional power supply so that the difference in the brightness of individual diodes is not very visible. Therefore, long tapes often have the option of double-sided power connection.
Types of Zamel LED power supplies in the Onninen wholesaler

There are several solutions for powering LED strips. The main difference between them is the method of installation:
- The simplest solution is the Zamel 14V DC 8W surface-mounted LED power supply with a power of 8 or 15W. Its biggest disadvantage is the lack of masking of the power supply, but this is not always a problem. In many cases, the device can be mounted under a cabinet or placed on top of a piece of furniture, where it will not be visible at all.
- If it is not possible to hide the power supply, it is worth using the Zamel 14V DC 15W LED power supply. Just use a hole saw to make a hole in the wall for the electrical box so that the connection of the LED strip remains completely invisible. This solution is often used in bathrooms to hide the device from moisture.
- In new installations, an interesting idea is to run the power line directly from the distribution box. This is a perfect place to install the Zamel 12V DC 15W modular LED power supply . It can also power several lighting points throughout the house, which in many cases will not only save a lot of work, but also reduce the costs of creating lighting.
- In addition to standard models, we also have a touch switch for Zamel WDN-01 LED strips . It functions as a typical power supply and at the same time allows you to dim the lighting or change colors. The mentioned model has three RGB control channels and is intended for LEDIX strips, modules and luminaires.
A large selection of solutions for powering LED lighting allows you to create aesthetic circuits that are well hidden from view. Thanks to this, the effect of such systems is even better.
How to install an LED power supply in an electrical box?
First of all, it is necessary to purchase the appropriate model of LED power supply. It will have the appropriate dimensions, so you can easily fit it into a standard electrical box. Also pay attention to the voltage and power of the power supply so that these parameters meet the requirements of the installed lighting. Then, lead the cables to the installation site. Most often, they are hidden under a layer of plaster to increase the final aesthetics.
It will therefore be necessary to drill a hole with the diameter of the box and make channels in the wall for cable routing. Connect the power cables (phase and neutral) and the LED strip terminals (plus and minus) to the power supply. All inputs are clearly marked on the power supply. Once connected, you can turn on the lighting to test its operation. If the diodes light up properly, you can seal the channels and close the box with a lid.
