Hi everyone,

I’m a beginner when it comes to electrical work and could really use your help. I recently purchased a TP-Link dimmer switch to control the brightness of the four LED spotlights in my kitchen, which are all connected to the same switch. (See the picture)

I confirmed my spot LEDs are dimmable and all four spots are controlled by only one switch. 

When I opened the switch box, I noticed there were two red wires and two black wires, and I’m not sure how these relate to the four spotlights. The new TP-Link dimmer switch has the following connectors: one line, one load, one neutral, and one ground. The neutral and ground wires are present in the box, so that’s not an issue, but I’m confused about how to deal with the red and black wires and whether I need a different type of switch for this setup.

I’ve installed basic switches before, but this is my first time dealing with something like this. Does anyone know how I should approach this? Any tips or advice would be greatly appreciated!
