I have a 600 foot driveway. 120 volt running up the length fo the drive. Six crappy fixtures - dual floods - zip tied to trees when the house was built. I did a small project with Volt low voltage products to light an entry path to our studio. Loved the results. Wondering if I need to stick with line voltage, or should consider multiple transformers and low voltage lights? The cost and selection seem a lot better for low voltage?
