As a professional landscape lighting designer seeking to install and operate a new low-voltage lighting system, you need to consider which transformer to use to convert the 110-120V standard line voltage socket to an outdoor low-voltage 12V-15V lighting design. As an outdoor lighting installation procedure, this consideration can make your landscape lights work for many years in the future, and will reduce landscape problems caused by lighting failures or insufficient final output power, thereby satisfying and attracting customers Many years to come.
Therefore, to answer the question about how many landscape lights and which transformer power I can connect, we must first look at some basic lighting design specifications and precautions.
1) How many lights will I install?
2) What is the total wattage and voltage amperage of the landscape lights installed in an area?
3) Which wire gauge size will I use: 18/2, 16/2, 14/2, 12/2 or 10/2?
A key note before you start: If you connect low-voltage lamps directly to a line voltage source, the higher voltage of 120 will cause them to burn out immediately. Therefore, a low-voltage transformer power supply must be used, which can then be plugged into the main power supply to operate the landscape lights correctly every night. If you do not have an available GFI socket, please place the transformer out of sight before installation, and ask a professional electrician to install one for the new low-voltage lighting system Led Street Light. If you use a more powerful magnetic landscape lighting transformer, it is always best not to exceed 80% of its maximum power rating.
Now, to determine the number of 12V lamps that you can use a low-voltage transformer to power externally, check the wattage and VA rating of the installed lamps. After considering and calculating the number of lights running on the system, you can look for a low-voltage transformer with a higher minimum wattage rating.
