LED lighting is characterized by low power consumption, high quality light and the ability to change the colors of the lights. Thanks to this, it works perfectly in bathrooms , kitchens or hallways - 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 is usually not a problem, choosing the right power supply may raise doubts. That is 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. Light is produced by a semiconductor made of silicon. It requires direct current to power it. The strength of radiation depends on the voltage, but it should be a maximum of several dozen volts.
Meanwhile, the socket is supplied with 230V AC. But what power supply should you order to obtain the appropriate output parameters? Much depends on where the LED lighting is installed. You can also come across two types of power supply devices - some of them generate a voltage of 12V, and others - 24V. What is the difference between them?
What is the difference between 12V and 24V LED power supply?
Currently, LED strips are produced 
powered by 12V and 24V. It is worth noting that both models draw the same amount of current. However, changing the voltage causes a shift in the chromaticity coordinates. Therefore, diodes powered by a 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 the individual diodes is not very visible. Therefore, long strips often have the option of double-sided connection to the power supply.
Types of Zamel LED power supplies at the Onninen wholesaler
In the Onninen electrical wholesaler you can find 
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 the power supply, but this is not always a problem. In many cases, the device can be mounted under a cabinet or placed on the top of a piece of furniture, where it will not be visible at all.
- If there is no way to hide the power supply, it is worth using the Zamel 14V DC 15W flush-mounted LED power supply. Simply make a hole in the wall for the electrical box with a hole saw 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 an excellent 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 LED strips Zamel WDN-01 . It functions as a typical power supply, and at the same time allows you to dim the lighting or change colors. The model in question has three RGB control channels and is intended for LEDIX strips, modules and luminaires.
A wide range of LED lighting power supply solutions allows for the creation of aesthetic and well-hidden electrical circuits. This makes the effect of such systems even better.
How to install an LED driver in an electrical box?
First of all, it is necessary to buy the right model of LED power supply. It will have the right dimensions, so you can easily fit it in 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, you need to 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 the same diameter as the box and make channels in the wall for running cables. The power supply should be connected to the power supply (phase and neutral) and the ends of the LED strip (plus and minus). All inputs are clearly marked on the power supply. After connecting, you can turn on the lighting to test its operation. If the diodes light up correctly, you can plug the channels and close the box with a lid.
