How much light do I need and how far apart should I space my lights?
The more ambient light around (streetlights, neighboring houses, etc), the more light you’ll need to make the path lighting stand out. In rural areas with low ambient light, less is more. Your eyes already adjust to the dark, and too much light can cause glare, making it more difficult to see. A little goes a long way. 5-10 watts of halogen light and 1-3 watts of LED for every 10 feet is fine.
