Make sure your landscape lights are 12v DC. Some setups are AC.lator or the chart to figure out the best gauge of wiring you'll need. I'm running 10 gauge runs out to 300 feet.
I am going to be adding some IR illuminators as well. These will be powered by my landscape lighting transformer (1200 watt capacity with 3 banks of 400 watts each).

Also measure the voltage, make sure it is within the perimeters for the IR.
I run 2 (500ma ea) off of my gate opener, it's 12v, and floats the battery at 13.8 vdc.
I actually bought this transformer about 15 years ago when we were living in a different house. LED landscaping lighting was not a thing back then. Everything was halogen. So the watts really added up if you're planning on installing 50 landscape lights at 30 watts apiece. Now these same fixtures are 3 watts! So 50 lights now only draws 150 watts. So yeah, I have way way more capacity than I'll ever need. Good thing I saved the transformer though (I have two). These things are VERY well built and heavy as heck. The case is all stainless steel.Wow!
