The choice of a LED product is guided by watching specifications tables. Here is one table accompanied by the explanation of the features. The result should be a good lighting solution that is leaving a green ecological footprint. A good lighting solution is emitting enough light that the tasks in space can be conducted properly. First the lumens of the fixture (responsible for brightness in the room), the CRI (how good is the lighting concept representing colors), color temperature (how is the ambience in the room) and lumen per watt (efficiency of the system) are recommended to be watched. These criteria are responsible for a good lighting quality and energy efficient solution.

The other features are necessary information too. They serve further details about the fixture, the setup and maintenance of the lighting system.

(1) Type: The products name is a detail for purchasing the fixture

(2) Wattage: Defines the energy consumption of the fixture, which is important for the electrician and the ecological footprint of the system (referring to Lumens per Watts)

(3) CRI: Important character in areas where colors should be truly represented. For applications where people are involved, a CRI lower than 70 is not recommended. In shopping areas a CRI of 90 and higher is applicable.

(4) Lumens: responsible for the brightness in a room. The more lumens, the brighter the fixture is illuminating the space.

(5) Lumen per Watt: Efficiency of the lighting system. The higher the lm/W the better the ecological footprint of the product.

(6) Lumen Maintenance: how fast LEDs lose their brightness compared to new products (most manufacturers refer to the time when most of the LEDs reach 70% and less of the initial lumen output)

(7) Color Temperature: defines the mood or ambience in a room. Low quality lighting fixtures mostly have a very cool color temperature as these LEDs are more efficient than warm white LED products. A color temperature higher than 6000K is not recommended for a lot of areas.

(8) Beam Angle: the light is radiated into the indicated beam angle. LEDs are direct light sources with typical beam angles of 120° till 180°.

(9) Life Hours: defines the lifetime of a LED product. LEDs last 50,000h up to 100,000h.

(10) Replaces: a helpful information for replacing conventional light sources

(11) Working Voltage: high quality LED products have an integrated driver, Retrofit Solutions are delivered with the suitable ballast already.

(12) Frequency: detail about the admitted voltage frequency

(13) Power Factor: Efficiency of the ballast

(14) THD: Total harmonic distortion is describing the distortion caused by ballasts and other inductive loads of the input current on alternating current (AC) power systems

(15) Operating Temperature: The light source is operating under the mentioned conditions according to the manufacturer datasheet, other temperatures will cause the light source to fail or work not properly (e.g. light loss, different color temperature)

(16) IP Rating: the protection of the light source, ballast and wiring against liquids and solid objects

(17) Dimmable: dimming is the change in light source brightness, mostly undertaken by smart controls

(18) Dimensions: the fixture’s size, important for the definition of the mounting position and space

(19) Net Weight: the fixture’s weight, important for the mounting construction, e.g.ceiling strongness needs to be considered

(20) Housing: the housing is the surrounding of the light source and ballast, the higher the IP rating, the better the protection against liquids and solid objects which is important in car washes for example, the coating is important in swimming halls where the luminaires are exposed to chloride and humid conditions

(21) Mounting: possible mounting ways like pendant, surface or hock mount

(22) Warranty: how long after purchasing, the products are ensured working properly

Today, there are three things that are impacting outdoor lighting trends, taller elevations, the shift from brown-based to grey-based exterior materials and the continued desire for Outdoor Living elements and accessories. Together or separate, these changes are having an impact on outdoor lighting.

Taller

For almost ten years now, the height of interior ceilings has been shifting from a longstanding norm of eight-foot to a minimum of nine-foot tall. Many homes and many geographic areas are seeing minimums of ten and even twelve-foot. Homeowners love the expanse this provides. The unintended result of this growth is taller exterior elevations. Because of these increases in the exterior elevation and the commensurate growth of exterior door size and height, the standard, wall-mounted lighting fixtures that flank the doors and garage of a home had grown. Gone are the 8” porch lights of the past. Consumers must seek out taller exterior lighting to compliment the extended expanses outside.

Occurring almost concurrent with the interior ceiling height increases has been a growth in urban infill architecture. Central city lots are not the same as suburban plots. They often were extremely narrow, but also quite deep. The resultant architecture is significantly narrower and usually over two-stories tall. A three-story or four story façade again warrants a taller lighting fixture, but these must also be substantially narrower. For this type installation, seek out narrow and tall lighting.

From Brown to Gray

The dominant color of residential exterior has been beige/brown/tan for an extremely long period of time. Over the last five years, a larger and larger percentage of new homes have been using grey, slate, black and even white. Stones, siding, roofing, trim and windows are all experiencing this shift. Exterior lighting has primarily been some form of bronze. That is shifting now to colors and finishes that work better with the new material palette. Look for more black, variants of grey and even aluminum, stainless and nickel finishes. Each of these will more effectively compliment the new colors.

Keep in mind that there is a fair amount of regionalism in this particular trend. Housing colors in “dessert” areas (Phoenix, Southern California, Nevada, Florida and parts of Texas) where stucco homes are de rigueur will not see this shift. The stucco is naturally beige and roofing must be terra cotta to withstand the elevated temperatures. It is highly unlikely to see the demand for bronze-based finished altering here. Expect continued demand in these specific locations.

Outdoor Living Continues

The trend toward more and more outdoor use of a home shows no signs of stopping. Homeowners want to maximize their living space and extending to the home’s exterior is a natural reaction. There are typically thousands of square feet of living space outside. Why not use it? That space has been filled with kitchen equipment that rivals the inside and seating and tables that delivers the same type of comfort as interior furnishings. Look for lighting to follow this path. Exterior chandeliers continue to grow in popularity. Pendants and linear lighting have recently appeared. Landscape Lighting provided by LED remains a viable way to add interest to these outdoor spaces. Relatively recent additions are battery-operated LED Portable Lamps than can be positioned around the area to add light where people tend to congregate. All of these forms of light are designed to enhance the already inviting outdoor spaces.

It is interesting to note, this is not a regional trend. People in the north are as likely as southerners to equip their homes with these accessories. It is often said that northerners must pack 12 months of outdoor living into four or five months and they do that with gusto! Every outdoor is primed and ready for these products.

Outdoor Trends

A tertiary trend that is slowing gaining foothold is a more contemporary overall design. Initially this started with architect-driven homes and urban infill architecture, but more contemporary or contemporary-leaning residences are appearing. For that reason, an uptick in the demand for modern designs is becoming evident. While small today, it cannot be ignored. More will inevitably be employed in the future.

Outdoor trends in residential exteriors tend to be slow in coming and they typically hold for a longer period of time than interior trends. These shifts have been accelerating for a while now. When they peak, they will hold for a longer period of time. Our love for the outdoor seems inexhaustible.

When’s the last time you gave much thought to your home’s electrical system? Chances are that unless you’ve experienced a power outage or you’ve had circuit breakers tripping on a regular basis, it was not very recently. It’s important to realize that frayed wires, loose connections, and similar electrical problems are not unique to any one type of household—anyone can experience these problems.

Without appropriate repairs, these problems can short out important appliances or even start a fire. When it comes to repairing electrical problems though, you should only trust a trained and licensed electrician, such as the members of our staff. But the only way to know it’s time to give us a call for repairs is if you know the signs that a repair is needed in the first place. Keep reading to learn about these indicators.

If any electrical outlet in your home is warmer than the wall that surrounds it, even when nothing is plugged in, your wiring is probably experiencing some trouble. While warmth while something is plugged in is normal, an outlet should never be too hot.

Intermittent electricity will cause this to happen. This is another sign that something is wrong with the electrical wiring in your home and needs immediate inspection and repairs.

Malfunctioning electrical systems or components will often cause a low buzzing noise, which usually ceases when you cut power to the circuit.

If you notice that the breakers keep tripping on one particular circuit, then you’ve probably overloaded that particular circuit. It could also be a problem with one or more appliances hooked up to it.

You should never see sparks coming from any electrical outlet. If you do, be sure to shut the power off to the affected area immediately, and then call for professional repairs.
