Brass, Copper or Aluminum?

When dealing with low voltage lighting, fixture quality is very important. Remember that when you are installing outdoor lighting, the fixtures are exposed to the elements, and are close to the ground where moisture can threaten their lifespan. Lighting fixtures are prone to corrosion which will hurt the electrical connections in the long run.

                                                 Which is best for you? 

High-quality fixtures may be constructed out of brass, copper, or aluminum. Brass and copper have the advantage of better weathering corrosive environmental elements. In fact, aluminum fixtures are not recommended for use within 25 miles of salt-water coast line. Even inland, brass and copper will generally outlast aluminum fixtures. 

Most low-cost aluminum fixtures use recycled aluminum and as a result they have impurities. These fixtures will very quickly start to pit and corrode in as little as 1 year. Better made aluminum fixtures are constructed with virgin, high-quality billet aluminum, and are treated with a durable, protective finish.

Aluminum does dissipate heat more efficiently, but brass and copper fixtures are engineered with heat sinks and thermally tested to ensure they can operate properly with their paired light source. 

Instead invest a little more in high quality, professional architectural grade lighting. You will be rewarded every day with superior landscape lighting.
