Coastal Source landscape light fixtures are made completely of brass, right down to the nuts, bolts and stakes. These fixtures are 100% sealed to keep out moisture, corrosion, debris and bugs. Why is this important? Because light bulbs eventually burn out and need replacing. Typical landscape lighting fixtures become so corroded within a matter of months that they can’t be opened to change the bulb. At that point, not only do you need a new light bulb, you need an entirely new fixture. Not anymore. Coastal Source outdoor light fixtures are built to stand the test of time and weather for years on end.
