Nowadays, more and more led strip lights project are everywhere. However, choosing a great led strip power supply is the key for the project to every contracter.

And how can we choose a right led power supply option?

The first option would be to go with a plug-in power brick. Wall mount or desktop power supplies will plug directly into your wall outlet and switch the line voltage down to 12VDC for the strips. This is handy for smaller applications or in spots where you have a hidden outlet that is out of the way. It certainly makes wiring easier as you just plug in and don’t have to connect wires directly to main lines. For example, if you have an LED strip light that requires 100 watts of power to run, you'll need a power supply that's rated for at least 120 watts led power supply.

This brings us to our second option, a waterproof power supply that connects straight to 120VAC lines and then outputs the safe, low DC voltage to your strips. These power supplies typically come in more discrete sizes and can be much easier to hide within walls or wherever needed. Caged, Open Frame Power supplies typically fall in this category as well and are very helpful with their screw-in terminal ports for easy connections and multiple ports. This is definitely a more professional look than just plugging straight into a wall but it will require you to have main lines readily available by your lights.
