I found this great looking Moravian Star pendant light online at Shades of Light. At $450 it wasn't an inexpensive choice, but it gives the screened porch and that side of the house a nice touch of character. I put it on a dimmer (don't forget to consider this detail for most of your exterior lights). It makes it possible to set a variety of moods on the porch. I discovered after everything was in place that dimming the light at night also minimized the reflection of light on the screening...opening up the view from the porch after dark.
If you're on a budget, you're on a budget, but I decided to use exterior lighting that would give my new house a sense of a past...even if it's only in my imagination.
