I installed my own landscape lighting over the last two summers, and will do more next summer.
The summer of 2016 I did the back yard:
* Path lighting from the front driveway to the back yard.
* Lights on the risers of each stair leading up to the deck.
* Lights under the top row of the sitting wall around the fire pit.
The summer of 2017 I did the front yard:
* Path lights on the walkway from the driveway to the front door.
* Spot lights up lighting each column and corner of the house.
* Spot lights up lighting the bigger trees of the front beds.
Plans for the summer of 2018:
* Put spot lights on the corners of the house in the back.
* Put spot lights on the major landscape elements of the back (bigger trees, interesting bushes, etc).
* Wrap the deck railing, swing set and large, mature trees with solar fairy lights.
I used all Volt Lighting (linked above) equipment, transformers and fixtures. I got the wire and bulbs from amazon for significantly less than what Volt wanted for essentially the same thing. I used standard blue/red DryConn connectors that can be found at any big box store for the splices. (Also: get something
like this, it made my stripping life way more manageable.)
This is easily a DIY project. Volt has several good tutorials. Watch them and any others on YouTube. The biggest hurdle for me was tunneling under my front walkway in two spots. The builder of my house and walkway
put down a 16" base, which was an absolute bear to get under.
I'll try to get some pictures of at all this evening when it's darker.
Good luck!
