    LEDs, or light–emitting diodes, are semiconductor devices that when an electrical current is passed through them produce visible light. LEDs are a type of Solid State Lighting (SSL), as are light–emitting polymers (LEPs) and organic light–emitting diodes (OLEDs). The useful lifespan of LED lighting products in NJ is much longer than that of other light sources, such as incandescent or CFL. This is because Encore LEDs usually do not “burn out” or fail. Instead, they experience lumen depreciation, where the amount of light produced decreases and light color appearance can shift over time. Instead of basing the useful life of an LED product on the time it takes for half (50%) of a large group of lights to burn out (as is the case with traditional sources), LED product “lifetime” is set based on a prediction of when the light output decreases 30 percent.

    When making decisions about LED lighting, there are three important concepts to understand: Kelvin temperature, lumen output, and beam spread (lighting spread). Each light fixture or lamp will list figures for all of these, so let’s take a closer look at each term and what the numbers tell you.

    KELVIN TEMPERATURE

    When we talk about the color temperature of light, as expressed in degrees Kelvin (or “K”), we’re referring to the color of the light. The measurement is a scientific one based on the color of light radiated by something called an ideal black body at different temperatures—but don’t worry about the technicalities here. The thing to remember is that orange or yellow light is produced at lower temperatures (under 3000K) and blue light is produced at higher temperatures (over 4500K).

    This would be easy to remember except that when we talk about light in everyday conversation, we describe it in exactly the opposite way. We call the yellowish light of incandescent light bulbs “warm” (in part because the bulbs themselves are warm when they’re turned on) and the bluish light of fluorescent bulbs “cool” (in part because the bulbs are cool when they’re turned on). Our use of “cool” and “warm” here has nothing to do with the Kelvin temperature of light.

    Keep this in mind when you’re comparing the Kelvin temperatures of different fixtures: the lower the temperature, the “warmer” the light. Candlelight is about 1850K, noon sunlight is about 5000K, overcast light is about 7000K and a blue sky is about 10,000 K.

    One of the drawbacks about the early LED lighting is that the LEDs often had a bluish cast to them—they had a high Kelvin temperature. It’s still true of less expensive LEDs. If you don’t want that blue light, make sure you select lamps or fixtures with a relatively low Kelvin temperature. The range of temperatures in landscape lighting is from about 2700K to 4200K and up, with 2700K being yellower, “warmer” light, 3000K being a clearer “pure white” light and 4200K being bluer, “colder” light. You’ll want to pick the lighting style you like most—though it’s worth noting that the “warmer” LEDs tend to be more expensive.

    LUMENS
    Before the advent of LEDs, most light bulbs were incandescent, and you could tell how bright they were by how much power they consumed. So if you needed to replace a lightbulb, you’d look at the wattage on the top—35 watts, let’s say—and go to the hardware store to pick up a new 35 watt bulb. So people got used to talking about lamp brightness in terms of watts, which worked fine at the time even though watts aren’t really a measure of brightness.

    When LEDs came on the scene it generated a lot of confusion because they could generate a lot more brightness using a lot less power—so we needed a different measurement for brightness. That’s why we started using a unit that measures brightness called “lumens.” Using lumens, we can now compare all kinds of different lamps based on their brightness. Let’s look at a chart comparing the lumen outputs of the most common landscape lighting bulbs:
    BEAM SPREAD
    The last concept you’ll need to understand is beam spread. If you think of the beam emitted by a landscape lighting lamp or fixture as a cone, or, when seen from the side, a triangle, the beam spread is the measure of the angle at the top of the cone or triangle as it leaves the fixture. It’s measured in degrees—not degrees Kelvin, but degrees of a circle, from zero to 360.

    In landscape lighting, different beam spreads are used for different purposes. If you want to illuminate a wide area down low, like a rock wall, you’ll want a wide beam spread (usually called a “flood” light), most commonly 60 degrees. If you’re lighting a small tree, you will probably want a medium beam (35 degrees) that will reach the top of the tree with more light. If you’re lighting a tall tree or something narrow like a column, you’re looking for a narrow beam spread—a spot light—15 degrees.

    With these concepts in mind, you’ll be ready to confidently specify your lamps or fixtures, and be sure that you’re getting the illumination you’re looking for.

    Outdoor lighting bulbs can burn out too often if they're installed improperly. For example, if the voltage going to each bulb differs, you'll end up with bulbs of varying degrees of brightness that tend to burn out frequently

    There are a number of basic reasons for LED lights to fail but the primary issue is heat. Over-heating can be a result of a number of design and assembly issues but is still the cause of the majority of LED lamp failures – both in the fitting themselves and also the drivers.

    There are numerous design aspects to consider when undertaking and designing a landscape design from scratch, lighting being one of them.

    When working on a new (or refreshed) landscape design it is understandable that for you, the landscape architect or designer, the landscape and planting is number 1. After all, the landscape and plants are your specialty. So when it comes to the landscape lighting, use a lighting professional to design your lighting plan - allow that part to be taken off your plate.

    For those homeowners who are taking on this project yourself, we recommend that you do not use your landscaper who mows your yard every week or the one who does your seasonal color. Often times they really do not know how to create a professional lighting plan correctly, and you will be the one who pays dearly.
