When you set out to purchase fixtures you may be presented with options for bulbs or fixtures with various beam angles. To choose the correct beam angle you must consider the distance between your fixture and your subject. You must also consider the size of your subject area.
Professionals also consider the power of the lamp (lumens) as well as foot-candle. We will not go into professional level detail here, but we will give you the information to make an informed buying decision. We will also provide handy calculators to help you determine the optimum bulb for your specific environment.
LED stands for Light-Emitting Diode. It is assembled into a lamp (sometimes called a light bulb) for use in lighting fixtures.
So What Then is an LED?
Technically speaking an LED is a two-lead semiconductor light source that is a p-n-junction diode. When voltage is applied to the leads, electrons are able to recombine with electron holes releasing energy in the form of photons thus emitting light. The color of the light is determined by the band gap of the semiconductor.
In the past we would never consider LED (Light Emitting Diode) as an option for landscape lighting. Only halogen bulbs provided the professional look that clients demanded. LED lamps were unreliable and frequently failed shortly after installation.
Now when consumers think of LED, many immediately think of the solar powered LED landscape lighting that are sold at big box retail stores. That lighting is unnatural and underpowered. Additionally the fixtures are frequently plastic or aluminum and are marginal quality which will not stand up over time. This is why they only carry a one-year warranty.
When it comes to professional grade landscape lighting, LED has become the number one choice for professional designers and installers. Reputable outdoor lighting firms only install LED fixtures that are made of solid brass and carry a lifetime warranty.
Let’s take a look at why LED is now the best choice for professional landscape lighting.
