The best way to go green is lighting your garden with solar spot lights. With no wires there is also no hassle, these spotlights run solely on solar energy but also include three back-up rechargeable batteries. As soon as it gets dark your spotlights will turn on, automatically brightening up your garden so you can enjoy it at night as much as you enjoy it during the day. To be sure your spotlights can retain enough solar energy place in direct sunlight.
