A Guide to Commercial Lighting Fixtures

Although incandescent lamps are more frequently used in residential lighting applications, some commercial lighting fixtures also used this technology. Incandescent lamps pass current through a filament, which causes the filament to give off light. Because they are relatively short lived, incandescents are used mostly as decorative commercial lighting fixtures. Their ability to render warm colors effectively without ballast makes them well suited to this application, and the enormous variety of bulb designs make them highly soft after source of any type of accent lighting or decorum based commercial lighting design.Fluorescent Lighting Fixtures
Fluorescent lamps are used extensively in commercial lighting fixtures for a number of reasons. First and foremost of these reasons is their ability to use less power than other commercial lighting fixtures, making them very cost effective from an energy conservation perspective. Fluorescent bulbs also produce a very bright light that is evenly distributed, making them ideal commercial warehouse lighting fixtures, canopy lights, security lights, in interior retail lights in discount stores where high levels of general lighting help psychologically motivate larger bulk purchases of discount merchandise.Fluorescent bulbs produce light by activating phosphors on the interior of the bulb using ultraviolet energy generated by a mercury arc. Ballast helps start and operate the fluorescent lamps by regulating electron flow through the gaseous arc. Trends in fluorescent technology have made them more compact, increasing lumens per watt efficiency as high as 100 lumens per watt, and reducing the amount of toxic mercury within the bulbs interior. Fluorescent commercial lighting fixtures are best deployed underneath building eaves (as in the case of canopy lights), near loading docks, in wall packs on the sides of buildings, or as large grocery store or warehouse lights. Placing them too far out into open spaces tends to diffuse their light output and diminish their intensity.High Intensity Discharge (HID) Commercial Lighting Fixtures
HID stands for High Intensity Discharge. It refers to a technology where light is produced by a gaseous arc discharge using a variety of elements. Typical elements include mercury vapor, metal halide, and high pressure sodium. The arc tube within an HID lamp will contain one or more of such elements, and when current passes between the electrodes at either end of the tube, the current creates an arc that generates visible light.HID lamps feature the highest efficiency in lumens per watt output and also feature a greater level of lighting control. They also last longer than other commercial lighting fixtures, making them a wise investment for a company on a Spartan budget that cannot afford to continually replace equipment. High intensity discharge sources include mercury vapor, metal halide, and high pressure sodium (HPS) lamps. Light is produced in HID and low pressure sodium (LPS) sources through a gaseous arc discharge using a variety of elements. Each HID lamp consists of an arc tube which contains certain elements or mixtures of elements which, when an arc is created between the electrodes at each end, gasify and generate visible radiation.Light Sources and Lamp CharacteristicsMercury Vapor (MV) Lighting Fixtures
Mercury vapor lights were the first HID commercial lighting fixtures developed. They were designed originally to meet a rising demand for a very compact, high output, and energy efficient source of light. They are used extensively in a number of landscape lighting applications, being commonly deployed as tree lights in high-end commercial outdoor lighting systems. In other applications they have proven somewhat less effective duo to their inferior color rendering abilities, although this has improved to a certain extent over the years by phosphor coated interior bulb walls.The life of mercury vapor lamps is good, averaging 24,000 hours for larger wattage lamps. However, because the output diminishes so greatly over time, economical operational life is often much shorter. Efficacy ranges from 30 to 60 lumens per watt, with the higher wattages being more efficacious than the lower wattages.As with other HID lamps, the starting of a mercury vapor lamp is not immediate. Starting time is short, though, taking 4-7 minutes to achieve maximum output depending upon the ambient temperature.High Pressure Sodium (HPS) Light Fixtures
High Pressure Sodium (HPS) commercial lighting fixtures gained huge popularity in the 1970s to meet the needs of a powerful, yet super efficient, source of HID lighting. Lumens per watt output in an HPS lamp can be as high as 140 lumens per watt, approximately 7 times the luminance as incandescent lamps and twice that of MV or Fluorescent. They also last for approximately 24,000 hours—the longest lamp light on the market.The problem with HPS commercial lighting fixtures has always been the quality of light they create. HPS lamps give off a yellowish or orange-tinted color and are not acceptable light sources for situations where illuminating a brand, architectural keynote, or any type of ornate exterior landscaping requires a high level of color rendering. For the most part, they are used in applications such as commercial parking garage lighting, warehouse lighting, and certain outdoor applications such as security flood lighting.Metal Halide (MH Lighting Fixtures
Metal Halide (MH) commercial lighting fixtures are fast becoming the preferred source of HID lighting in most commercial environments. This is because they produce a very bright white light that nearly equivalent to daylight in its color rendering ability. The variety of applications is significant as a result, ranging from decorative street lighting, commercial parking lot lighting, car lot lighting, outdoor landscape lighting, architectural lighting, security lighting, and general site lighting. Traditionally, their biggest drawback has been their short lamp life, only 7,500 hours on the average.Newer designs in Metal Halide commercial lighting fixtures include pulse start technology and ceramic metal halide design. These improvements have increased lumens per watt efficiency, control of the light itself through superior dimmability, better stability of color rendering, longer lamp life, and shorter start time.Unfortunately, recent legislation has called for the phase out of certain standard forms of MH commercial lighting fixtures due to their use of incendiary elements that fall under the classification of greenhouse gas sources. This in turn paves the way for the most sophisticated lighting ever developed on our world, and quite possibly, the singular source of lighting used both commercially and residentially in the very near future: LED commercial lighting fixtures.LED Commercial Lighting Fixtures
As technology improves, the ability to create truly white LED light continues to evolve. LED commercial lighting fixtures are featuring higher lumens per watt efficiencies than their initial prototypes initially offered. This has opened the door for a number of architectural lighting and site lighting applications that were previously the exclusive domain of HID commercial lighting fixtures.We are also seeing an upsurge in the use of led commercial lighting fixtures in street and roadway lighting, where a number of municipalities in the United States and Europe have reported some very promising findings in regards to both power cost reduction and the overall quality of street lighting itself.Look for quarterly leaps and bounds in the engineering gains made by LED commercial lighting fixture manufacturers.

Red Flags When Buying Online Health Insurance

In the past, without the Internet, everything is done via the telephone or person-to-person meeting. If you need to buy an accessory for your car, you will have to drive to the car accessories store and make the purchase. If you are hungry you need to go to the restaurant or fast food chain to order and get your food. If you need to meet with a client overseas, you will have to book a flight to go to that country.That was in the past. Today, many thanks to the Internet, everything is done online. For anything you need, an online store is offering and you don’t have to get up from your chair to do that. All it takes is a click of the button on your computer screen.

Any website that does not have the icon (lock symbol) or other indicators of security on their webpage should be avoided. They should place high priority on the security of information passed to them.5. You should receive the original insurance policy and not just the printed form even if you have purchased an online health insurance. The Internet is just a tool used for the initial sales transactions. All the legal documents that need to be signed should be original and carries the insurer’s company seal with the company’s authorized signature. Be sure to check all the documents carefully to make sure they are legitimate documents from the insurer.It may be daunting and a little intimidating when you shop for health insurance online but it’s the easiest and fastest way for you to collect the information, assistance and selection you need. You just need to be observant and extra careful when dealing with just the screen of your desktop.

Digital Marketing – Incremental Revenue

Social media advertising can have a big impact on a brand. Digital marketing ads may encourage people to try a product, a free trial could lead to a purchase, and a purchase could lead to a person actually using a product. During this process, brand-centric conversations usually develop on social networking websites, which can be discovered through search. These conversations become a vital factor when it comes to making purchase-related decisions, as most buyers usually check out comments on social networks like Facebook before coming to a buying decision.These digital marketing conversations are usually driven by two factors, which are both controllable. The first is product design, and the second is the communications between customers and customer service agents. There is a strong connection between ROI and customer service. For instance, if an internet marketing professional takes the time to understand the relationship between the number of fans and the number of ‘likes’, together with conversations on Twitter between customers and service agents, they will get a true picture of the impact of their digital marketing campaign on social networks.A simple way to get such an understanding is to connect customer service actions with incremental ‘likes’, by tracking responses of customers to the digital marketing messages of your customer care agents. You may also begin tracking incremental revenue, either directly through your Facebook business page or other social media profile. So, what is incremental revenue? Incremental revenue can be in the form of subscription renewals, product up-sells, and customer saves collected through the actions of social care agents.Incremental revenue can also be calculated from the expense side, just like a phone interaction. Once you track the shift of call deflection, you will get a measure of the change in expenses connected with your digital marketing effort, together with its cost. Your digital marketing programme on social networks will now be connected to real money, offering a great way to calculate ROI.As an Internet marketing professional continues to build their marketing programme on social networking websites, it is important for them to think beyond marketing. A social media profile should also link to other functional areas of a business, which also take part in social media-based conversations, such as customer service. Take into account revenue, expense change and directional KPI’s, before setting up various ROI goals. Therefore, there are a number of ways in which you can also improve product promotion through Social media.
