I never really authored a post on landscape lighting. It is a simple and inexpensive way to enhance the beauty of your home and provide a bit of safety at night.
You don't have to do this (underwater, water-tight)...
But more simple applications...
1. Pick a cast/metallic light especially if you live in harsher (read snow) climates
2. Have a plan
3. Highlight the main objects for effect & task light the areas around walkways for safety
4. You do not have to spend a fortune for a decent plan
