Halogen Landscape Lighting versus LED Landscape Lighting

There are three areas that need to be considered when comparing Halogen and LED landscape lights.

Both LED luminaires and Halogen luminaires convert electrical power into useful visible light. Both technologies create heat as a by-product of the conversion of electrical power. However LED luminaires enjoy the performance advantage of creating less heat for every lumen of light that they produce. Typically a halogen luminaire will create 3 times the amount of heat that an LED luminaire will produce for every lumen of light that is produced.

Both technologies create light and heat from electrical power. The heat created is not typically useful when the objective is to create light and this can be considered a waste of power. Led luminaires also have an advantage as less power is consumed for every lumen of light produced when compared to Halogen luminaires. Typically a 50-70% electrical power consumption savings is achieved when using an LED luminaire when compared to an equivalent lumen output from a halogen luminaire. Since more power is consumed by halogen luminaires a proportional increase in the size (gauge) of the wire used at system installation will be required. This is a cost consideration.

All luminaires will require maintenance of the luminaires finish via some form of cleaning during the life of the luminaire. Because halogen luminaires run at higher temperatures there may be some extra effort expended in maintaining the finish do to the greater heat baking on dirt and debris. More significant though is the maintenance of changing the halogen bulbs periodically. Although halogen bulb life is specified by the manufacturer it is often not reached in practice as real world variables such as voltage fluctuations, voltage surges, and contaminants on the outer surface of the bulb all degrade the life of the halogen bulbs. LED luminaire lifetimes are such that a fixture should not require a “bulb” change for at least 50,000 hours. LED luminaires use a power converter, or driver, and this is typically the weakest link in an LED luminaire. Driver lifetimes are determined by several factors but a driver should typically be expected to last in excess of 10,000 hours. Since the halogen power consumption is greater the electrical current flowing through the wiring is also greater. A typical landscape lighting system includes many electrical connections or splices. This greater current flowing through the connections will cause greater heat to be created at the connections. This will cause the connections to have a larger voltage drop at the connections and hence more heat is created at the connections. This additional heat will increase the rate of degradation of an electrical connection.

Using Garden Light LED Luminaires with Crestron Controllers

To ensure your Garden Light LED luminaries can be easily integrated with a Crestron controller, always inform your sales person that luminaires will be used on a Crestron system when placing an order.

Design and engineering

While many fixtures are manufactured in foreign countries, Garden Light LED proudly builds all LED products in our Tampa, Florida factory. Garden Light LED fixtures are the product of intense collaboration and are engineered, designed, and assembled in the United States, allowing us to maintain the purity of the Garden Light LED standard.

Sleek and strikingly appealing, Garden Light LED fixtures are easily recognizable in quality and design. Made with our remarkable technology, they are individually handcrafted and machined from 6061 aircraft-grade aluminum and C230 solid brass billets. Designed for function, they also feature performance-oriented efficiency and visual sophistication.

In the industry, durability and longevity of the surface coatings and base material is crucial. We chose 6061aluminum for its high resistance to corrosion and high acceptance of applied coatings such as enamel, anodize, ecoating. In addition, 6061aluminum is highly machinable, making it an excellent choice for computer numerical control (CNC) machining. In fact, 6061 aluminum is widely recognized in the aerospace, super car manufacture, military specification, and marine industries for these characteristics. These benefits, combined with aluminum’s naturally high thermal conductivity, make 6061 aluminum a perfect component for high-performance LED lighting fixtures.

For our high-performance line of brass fixtures, C360 brass was a natural choice because of its high thermal conductivity, which is close to that of aluminum, and its excellent ability to resist corrosion. The use of 360 brass ensures that all Garden Light LED fixtures operate within our tight thermal requirements.

CNC technology

CNC stands for “Computer Numerically Controlled” It allows us to “program” the machine using a coordinate system. After which the machine will read and cut out the part. The programs can be simple or very complex our V2 body for example is 28 pages of code. The machine cuts the part from a solid bar of material. Often times the machine removes over half of the materiel to create the part. The CNC machine can work autonomously once setup, in our case we can load bars into the “bar feeder” and it will keep supplying the machine with materiel until it runs out. By manufacturing in America, we have much better control over quality, demand, and executing changes.  By using local suppliers of material, we can guarantee we get the high quality material that we specify.

What’s driving our drive system?

Garden Light LED’s drive systems are a landmark along our path of excellence.

To really understand the drive system that harvests and distributes power, 
we must first understand current (i.e., power distribution) and amperage. Most manufacturers use a constant current of 700mA or .7 amps, but Garden Light LED incorporates many different drive currents to achieve diverse levels of light output.

Our engineers have been continually improving our advanced drive system for years, and Garden Light LED drive systems yield an unparalleled efficiency rating.

In each fixture, the highly complex power train is tucked away tightly, concealing
a surprising amount of technology. 
LED technology components allow for innovations that are not possible with halogen bulbs. Garden Light LED’s fixtures are virtually indestructible and are specifically designed to work in tandem with the driving regimen. Particular optics allow for beam adjustability and a “point” source of light. With proper components and design, LEDs can last hundreds of thousands of hours.
