Exterior Lighting Denver

The function of high bay fluorescent lighting is to light surface which are more than 15 feet away. Some common kinds of high bay applications can be seen in gymnasiums, warehouses and factories etc. All lamps which are used in applications are consists of mercury (High-Bay Lighting: Opportunities for Mercury Reduction and Energy Efficiency, 2003, p 1, para 1). In recent times, both high intensity fluorescent technologies (HIF) and HID have gained popularity but the performance of HIF technology is understood better in many applications that is which has given HIF opportunity to gain market share. The improved technology of fluorescent lamps and the invention of new HIF fixtures have composed the most cost effective choice as fluorescent lighting for indoor areas like warehouses, big retail stores, factories and athletic facilities (Lighting: HID Versus Fluorescent for High-Bay Lighting, 2007, p 1 para 1).

History of fluorescent lighting:

Generally people associate lighting and lamps with incandescent light bulb which was invented by Thomas Alwa Edison and some other inventors. These kinds of bulbs perform on the basis of electricity and filament. When these bulbs are heated by electricity, the filament gets high temperature so it glows and gives light. Fluorescent bulbs like arc and vapor perform differently. The light does not come due to heat; it is produced through the chemical reactions, which happen when the application of electricity is on different gases encircled in a glass void compartment (The History of Fluorescent Lights, 2009, para 1).

In 1857 Alaxandre E. Becquerel discovered the fact of fluorescence and phosphorescence. He imagined the creation of fluorescent tubes as same as they are made presently. He did some experiments on coating electric discharge tubes, which were combined with luminescent materials. This was the procedure which further expanded in fluorescent lamps (The History of Fluorescent Lights, 2009, para 2).

In 1901 Peter Cooper Hewitt got exclusive rights on the first mercury vapor lamp (The History of Fluorescent Lights, 2009 para 3). His low pressure mercury arc lamps became the very first of its kind for today’s modern fluorescent type. Edmund Germer discovered a high pressure vapor lamp which helped in producing economical light with less heat. In 1927 he copyrighted an experimental fluorescent lamp. Some historians give Edmund Germer the credit of inventing the first true fluorescent lamp (The History of Fluorescent Lights, 2009, para 7).

T5 Lamps:

High lumen fluorescent systems are gaining a lot of popularity where T5 fixtures are presented in 4 and 6 lamps configurations whose effective process can be related to high bay applications. They are flexible systems which are some levels higher than any other high bay applications. It has following characteristics (High Bay lighting Solutions, 2007, p 3, para 1):

* It provides the most light with the help of the fewest lamps.

* It is good for using with occupancy sensors.

* It is ideal for maintaining lamp life in frequently switched applications.

* It has 120-277 volt and 347-480 volt ballasts.

* It can increase lumen output at 35 c ambient temperatures.

* It is specially designed for high bay applications.

* Its technology is very high which can reduce generated heat.

* It consists of thermal technology that can remove heat.

* It has the facility of additional energy savings (High Bay lighting Solutions, 2007, p 3, para 2).

Comparison with HID:

HID lamps are thought to be point sources as they throw intense light in a small area. These kinds of lamps can be used for distant purposes such as indoor and outdoor sports facilities, warehouses, factories, where the ceilings are high and street lightings are used (Lighting: HID Versus Fluorescent for High-Bay Lighting, 2007, p 1, para 1).

If we compare HID with HIF lamps some disadvantages of HID lamps have been observed (High Bay lighting Solutions, 2007, p 2, para 2):

* They consume high energy.

* They have warm up and restrike delays as they cannot be related with occupancy censors effectively.

* Their noise is not favorable for quiet ambient

* Their lumen maintenance is very low where significant reduction in lower output can be observed.

* The color is very poor. CRI rates between 60 and 70. Color also varies from one lamp to other lamp.

* Its matching efficiency is less than 80%.

Now if we see benefits of high lumen fluorescent systems it can tell the difference between them and HID (High Bay lighting Solutions, 2007, p 2, para 3):

* HIF are energy efficient. They can save up to 50% energy.

They are instant and they have no warm up time. They have good relation with occupancy sensors so they can save maximum energy.

* Its operation is not noisy instead it is quiet. Its sound has been rated A.

* Its color is excellent. CRI rates between 75 and 85. It does not have any color variation or shift over time.

* Its matching efficiencies are higher than 90% (High Bay lighting Solutions, 2007, p 2, para 3).

While calculating energy efficiency it is necessary to check the number of lamps as well as watts per lamp (High-Bay Lighting: Opportunities for Mercury Reduction and Energy Efficiency, p 3, para 4). For example four HO T5 lamps or induction fluorescent lamps are needed to create the same amount of light like HID lamp. If the lumens per watt are higher, we will need less electricity for light. If a lighting system uses less Kilowatt hr per year, a facility will use less electricity and it will pay for that (High-Bay Lighting: Opportunities for Mercury Reduction and Energy Efficiency, 2003, p 3, para 4).

Switching from HID lamps to HO T5 fluorescent lamps:

It has become a common trend to switch over from HIS lamps to HO T5 lamps that can increase energy efficiency in high bay lighting situation like warehouses etc. HO T5 and induction fluorescents (High-Bay Lighting: Opportunities for Mercury Reduction and Energy Efficiency, 2003, p 2, para 7):

* are capable of insant-on and instant re-strike.

* They can be applied on energy saving occupancy sensors.

* They can be regulated through dimming

* They have lower rate mercury content than HID lamps (High-Bay Lighting:Opportunities for Mercury Reduction and Energy Efficiency, 2003, p 2, para 7).

Recommendations:

Facility owners, architects and managers who use high bay lighting applications should opt for the most energetic efficient system where the lowest mercury content is suitable for making and reshaping projects. For improving colors projects should be evaluated carefully. A buyer should consult a lighting professional before buying lighting system. This ensures the whole project can be assessed to check energy efficiency, lighting level and suitable color depiction. You should tell your lighting professional that your company will like low mercury alternatives (High-Bay Lighting:Opportunities for Mercury Reduction and Energy Efficiency, 2003, p 3, para 9).

Denver Commercial Lighting Contractor

High Bay Lighting Fixtures
This type of commercial lighting is normally used in areas with high ceilings, normally above 15 feet, and can commonly be found in places such as gyms, shops, warehouses, factories and garages. This type of commercial lighting fixture uses a technology commonly known as High Intensity Discharge (HID). These type of lamps can attain the maximum amount of lighting to cover large areas.

Low Bay Lighting Fixtures
This type of lighting is more commonly used in warehouses and churches or areas where the ceiling heights are between 15 to 20 feet. This lighting gives the maximum amount of light without putting out too much glare.

Flood Lighting
This lighting is commonly used outdoors and also uses HID technology. These lights must be very bright to cover large areas such as football fields or loading areas. These lights are normally quite cheap and can be mounted on buildings, on the ground, or on poles.

Street Lights
These lights are installed on tall poles to provide a broad spread of light for the night time. They can be seen on walkways, streets and in parking lots. The poles that these lights are installed on are normally between 6 to 13 feet high and have to be able to withstand damp and wet weather conditions. Street lights are normally programmed to shut off during daylight hours.

Lighted Advertising Signs
Lights that are used to illuminated advertising signs are a great way to get your business to stand out from the crowd. These commercial lights are designed to attract the attention of passers and achieve this by using brightly colored neon lights. Some signs blink and change color to increase their attractiveness to potential customers.

Linear Fluorescent Lighting
This form of commercial lighting uses low wattage T5 and T8 fluorescent tubes. Fluorescent tubes are very energy efficient and lead to great cost reduction when used.

High Bay Fluorescents

Pulse-start metal halides, like their standard predecessors, fall into the category of High Intensity Discharge lamps, also known as HID lamps. On the average, a standard HID lamp performs with approximately 3 times the efficiency of an incandescent lamp. Even better results can be expected with pulse-start metal halide fixtures, which in spite of their approximately 20% higher front-end cost, more than pay for themselves over the course of a life span.

Increased lumen efficacy (lumens per watt) by as much as 24%.

While standard Metal Halides lead many sectors of the site lighting industry in the arena of LPW, it may very well serve both you and your clients to increase this efficiency by up to 24% by investing in pulse-start metal halides.

This may constitute the winning element of your bid if you are proposing an area lighting system in a major city such as Denver, Colorado where LPW efficiency regulations have recently change to 1 lumen per .05 watts. The power savings, plus the increase lighting output, could potentially represent an irresistible line item on your next proposal.

Higher light output per unit of electric power Pulse-start lamps produce more mean lumens per watt of electricity.

Improved lumen maintenance by as much as 15%

Pulse-start metal halides offer further competitive advantage over standard MH lamps by increasing lumens maintenance by as much as 15%. As standard HIDs age, they actually output less light. To compensate for this phenomenon, known as lumen depreciation, contractors will often slightly oversell the number of lamps so the overall system will maintain the desired lighting output for the duration of its lifespan. This, of course, costs the client more money.

If you really want to be competitive, show your clients how pulse-start metal halides are 6-15% better at reducing lumens depreciation-then show them a photometric study with fewer fixtures (and less costs) than your competitors’ proposals contain.

Extended lamp life
Many of the latest, US-manufactured pulse-start metal halide lamps can last as long as 15,000 hours. This is 5,000 hours longer than the estimated 10,000-hour life span of a probe-start lamp of the same wattage.

Sell your clients not only on the idea of a longer lasting light source, but on the money they will avoid spending on expensive labor fees to replace burned out lamps.

Superior Color Rendering, Warm Up Time, and Re-Strike Time
As MH lamps get older, their CRI depreciates as well. Pulse-start MH lamps, however, maintain a consistently higher CRI than probe-start equivalents. They also take only 2 minutes to warm up, and in the event of a power failure, normally re-strike in 4 or 5 minutes—much better for security lighting than standard MH lamps that take around 12 minutes to re-strike.

Pulse-start Metal Halides Work Best with Pulse-start Fixtures and Electronic Ballasts
Every contractor knows it is generally not a good idea to mix newer technology with older technology. Pulse-start lamps should be fitted to pulse-start fixtures and operated with electronic ballasts for maximum energy savings. Since your clients will be spending more money on the equipment itself, it will be necessary to show them some math to justify the added expense, and to promise them a return on investment.

Metal Halide Lighting Denver

Incandescent

Even though incandescent lamps are much more often utilised in residential lighting applications, some commercial lighting fixtures also utilized this technologies. Incandescent lamps pass existing by way of a filament, which causes the filament to give off light. Because they are reasonably short lived, incandescents are utilized mostly as decorative commercial lighting fixtures. Their ability to render warm colors effectively with out ballast makes them properly 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

Fluorescent lamps are employed extensively in commercial lighting fixtures for a quantity of reasons. 1st and foremost of these causes is their capability to use less energy than other commercial lighting fixtures, creating them extremely price effective from an power conservation perspective. Fluorescent bulbs also produce a quite bright light that is evenly distributed, producing them perfect commercial warehouse lighting fixtures, canopy lights, security lights, in interior retail lights in discount stores where high levels of general lighting help psychologically motivate bigger bulk purchases of discount merchandise.

Fluorescent bulbs produce light by activating phosphors on the interior of the bulb using ultraviolet power generated by a mercury arc. Ballast helps commence and operate the fluorescent lamps by regulating electron flow through the gaseous arc. Trends in fluorescent technologies have made them more compact, growing lumens per watt efficiency as high as 100 lumens per watt, and decreasing the quantity of toxic mercury inside the bulbs interior. Fluorescent commercial lighting fixtures are finest deployed underneath developing eaves (as in the situation of canopy lights), near loading docks, in wallpacks on the sides of buildings, or as huge grocery retailer 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 exactly where light is produced by a gaseous arc discharge employing a range of elements. Common components contain mercury vapor, metal halide, and high pressure sodium. The arc tube within an HID lamp will contain 1 or much more of such components, and when present passes in between the electrodes at either end of the tube, the existing creates an arc that generates visible light.

HID lamps characteristic the highest efficiency in lumens per watt output and also function a higher level of lighting control. They also last longer than other commercial lighting fixtures, producing them a wise investment for a organization on a Spartan budget that cannot afford to continually replace equipment.

High intensity discharge sources contain mercury vapor, metal halide, and high pressure sodium (HPS) lamps. Light is produced in HID and low pressure sodium (LPS) sources by means of a gaseous arc discharge utilizing a selection of elements. Each and every HID lamp consists of an arc tube which contains certain elements or mixtures of components which, when an arc is created between the electrodes at each finish, gasify and create visible radiation.

Light Sources and Lamp Characteristics:

Mercury Vapor (MV)

Mercury vapor lights were the initial HID commercial lighting fixtures developed. They had been developed originally to meet a rising demand for a extremely compact, high output, and power effective source of light. They are used extensively in a quantity of landscape lighting applications, becoming commonly deployed as tree lights in high-finish commercial outdoor lighting systems. In other applications they have verified somewhat much less helpful duo to their inferior color rendering abilities, though this has improved to a selected extent over the years by phosphor coated interior bulb walls.

The life of mercury vapor lamps is great, averaging 24,000 hours for bigger wattage lamps. However, due to the fact the output diminishes so significantly more than time, economical operational life is frequently significantly shorter. Efficacy ranges from 30 to 60 lumens per watt, with the greater wattages being far more efficacious than the lower wattages.

As with other HID lamps, the starting of a mercury vapor lamp is not immediate. Starting time is brief, though, taking four-7 minutes to accomplish maximum output depending upon the ambient temperature.

High Pressure Sodium (HPS)

High Pressure Sodium (HPS) commercial lighting fixtures gained large popularity in the 1970′s to meet the wants 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-roughly 7 times the luminance as incandescent lamps and twice that of MV or Fluorescent. They also last for roughly 24,000 hours—the longest lamp light on the market.

The issue with HPS commercial lighting fixtures has often been the top quality of light they generate. HPS lamps give off a yellowish or orange-tinted color and are not acceptable light sources for scenarios where illuminating a brand, architectural keynote, or any sort of ornate exterior landscaping calls for a high level of color rendering. For the most component, they are utilized in applications such as commercial parking garage lighting, warehouse lighting, and selected outdoor applications such as security flood lighting.

Metal Halide (MH)

Metal Halide (MH) commercial lighting fixtures are quick becoming the preferred source of HID lighting in most commercial environments. This is since they create a really bright white light that almost equivalent to daylight in its color rendering ability. The range of applications is significant as a result, ranging from decorative street lighting, commercial parking lot lighting, automobile lot lighting, outdoor landscape lighting, architectural lighting, security lighting, and common website lighting. Traditionally, their greatest drawback has been their brief lamp life-only 7,500 hours on the typical.

Newer designs in Metal Halide commercial lighting fixtures consist of pulse start off technology and ceramic metal halide design. These improvements have increased lumens per watt efficiency, control of the light itself by way of superior dimmability, much better stability of color rendering, longer lamp life, and shorter commence time.

However, current legislation has called for the phase out of selected regular types of MH commercial lighting fixtures due to their use of incendiary elements that fall beneath the classification of greenhouse gas sources. This in turn paves the way for the most sophisticated lighting ever developed on our planet, and really 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 technologies improves, the capacity to develop actually “white” led light continues to evolve. LED commercial lighting fixtures are featuring greater lumens per watt efficiencies than their initial prototypes initially offered. This has opened the door for a amount of architectural lighting and web 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 quantity of municipalities in the United States and Europe have reported some very promising findings in regards to each energy price reduction and the overall high quality of street lighting itself.

Look for quarterly leaps and bounds in the engineering gains made by LED commercial lighting fixture manufacturers.
