Led garden lights

Looks complex with a lot of fiddling and as you add LEDs over time, lengthening the series strings, you're going to have voltage/line loss. What are you thinking of using as a 12 volt power supply?

There are plenty of garden light LEDs available that are already rated at 12 Volts. You can also go with solar LEDs. Some of the solar stuff is kind of cheap & the batteries don't last, but you could set up a 12 volt system with a larger deep discharge battery that can be charged either by a good sized solar panel or a battery charger.

What you're considering with these drivers is certainly doable, but you'll have to encase the drivers in something to keep them dry and you'll be restricted to using 3 watt, 700 ma LEDs which will also need to be weather proofed.
