lighting is responsible for a significant proportion of energy costs

Both in the home and the workplace, lighting is responsible for a significant proportion of energy costs. Lights being left on when they are not needed or operating at a higher intensity than is required is wasteful in terms of both financial costs and natural resources. Furthermore, the excess energy usage makes a substantial contribution to the carbon footprint of homes and businesses. By installing lighting controls, it is possible to curb these waste, pollution and financial factors.

Dimming controls
One type of lighting control provides automatic dimming and Industrial Led Lamps brightening according to the amount of daylight entering the room. In-built sensors detect the presence and intensity of natural sunlight in an office or living room for example, and use digital controls to set the output of electrical lights accordingly. This is a highly effective energy conservation strategy as it ensures that only as much electrical light as is needed is used. For example, in an office with plenty of windows on a day of changing weather, the lights will dim as the sun comes out, and brighten as the sky clouds over.

Motion Sensor lighting
Occupancy control is particularly useful for areas of the workplace that are used infrequently but are subject to a high volume of traffic, such as the staff kitchen or bathrooms. These controls use motion sensors to detect whether anyone is in the room, and, after a pre-set period, switch the lights off accordingly. When a person enters the room again, the occupancy control system will turn the lights back on. This is a vital way of saving on energy usage, as it ensures that lights are only used when they are needed without relying on human factors such as remembering to switch the lights off.

Other lighting controls can be used to prevent energy waste by automatically turning the lighting on and off as it is needed over the period of a day. This is highly effective in places such as office blocks that operate on a predictable daily schedule. Lights can be set to turn on at a specific time of the day, such as just as staff are arriving for work, and then turn themselves off at the end of office hours. They can also be programmed to be inactive at weekends if necessary.

Lighting Ballasts and increased energy efficiency
A range of electrical ballasts is available to provide optimum lighting control. The electronic Tridonic Atco Ballast for dimming provides users with precise controls. With a dimming range of 1-100% of full output, the ballast enables users to set the light intensity to suit their needs or the time of the day.

For high intensity discharge lamps, digital and electronic ballasts can be used to regulate the current supplied to the lighting and thus provide greater efficiency. A range of Newlec High Intensity Discharge Ballasts are available from 70W to 400W, providing low power losses and increasing the overall efficiency of emergency lighting solutions.

The bulbs of these piano lamps are smaller than those of other lamps

Although many of us do not stop to consider how useful a piano light can be to a practicing musician, those of us who play the piano know that we could hardly live without one. Piano lights have been adding style and a touch of pleasurable aesthetics to player's instruments for years. Any sort of piano - grand, digital or simple - can be made to look even more attractive with the help of a lamp. And, most importantly, a lamp will work wonders for a musician attempting to read music in an otherwise dark room. 

Often the proper type of lighting is needed to read music; a lamp which creates a glare upon sheet music is not an especially effective one. In the old days before electricity became a widespread phenomenon, people used candles to light a room for a piano performance. These looked beautiful to those in attendance, but musicians may not have enjoyed them as much because of the low light levels and the glare of the flame in their eyes. Nowadays, LED lamps are made so that sheet music may be illuminated without the backlash of a glare. Musicians will be able to quickly skim the musical notations in front of them without having to squint to see them. 

Today, thanks to modern technology and new developments in piano lighting, playing the piano is much more fun than in the days before electricity. Pianists have any number of options in front of them to light their sheet music and help them find the right keys. Obviously, it is up to the individual musician as to which type of light to choose much is determined by taste, preference and the type of piano a musician has at home. 

Of the several types of piano lamps available, the desk piano lamp is a particularly popular option because it is so flexible. It is well suited for a number of environments because it is adjustable both at the top of portable work light Manufacturers the stem and at the base of the unit. These also come in a number of different sizes, so that a player can purchase one suited for the size of their piano. The desk lamp comes with a shade over the bulb, so that light is only shining on the sheet music, and not making pianists squint. The best thing about desk lamps is that they come in many aesthetically pleasing forms, with a wide range of finishes that will not only compliment the piano but the piano's interior surroundings as well. 

The LED piano lamp is another that has increased in popularity in recent years, especially loved by musicians for the convenience it creates. LED lights are increasingly used in all of their forms because they are so energy efficient; pianists love them for this reason as well, in addition to their slim design. The bulbs of these piano lamps are smaller than those of other lamps used for the same purpose, allowing the LED lamp to be smaller overall. In addition to being good for the environment, the LED lamp is also a cost effective way to light sheet music.

You should be able to buy fixtures especially designed for LED tube light bulbs

You will have to make some simple modifications to the fixture to properly install the bulbs. The good news is that installing LED tube lights in an existing fluorescent fixture is relatively simple. In addition, you should be able to buy fixtures especially designed for LED tube light bulbs in the near future, and they should actually be cheaper than the equivalent fluorescent fixtures.

Fluorescent fixtures are designed to support a specific types and size of fluorescent tube. A fluorescent tube is incorporated into a fluorescent lighting system which consists of two or three main components of the fluorescent lamp (fluorescent bulb or tube), the ballast, and of course the starter system. Additionally, the system for a tube lamp includes a lamp holder and a switch. Depending on the particular fluorescent lighting system, the starter may be a replaceable component, a starter may not be required, or the starter function may be integrated into the ballast. The starting function may also rely on the physical design of the fixture. To retrofit a fluorescent light fixture to support a LED tube light, the ballast must be disconnected.

Once the old traditional bulbs are removed from the lamp holders and the electricity to the fixture is turned off, you will probably have to remove the reflector that is located behind the bulbs and provides a housing for the wiring and ballast that lie behind it. Typically, it is fairly simple to remove the reflector or cover, but if it is not clear how to do this, you should consult the documentation from the fixture manufacturer.

If the fixture has an electronic ballast, you only need to remove that and then wire the power directly to the lamp holders, completing one circuit for each bulb. This is fairly simple, and typically you can use the existing wire in the fixture and then just add some wire nuts. If you have an older fixture with a magnetic ballast and starter, you will have to remove or open the starter and remove or short the magnetic ballast.

Depending on how much wire you have to work with, it is a good idea to leave long enough wires leading out of the ballast to be able to reconnect the ballast with wire nuts, if you should ever want to convert the fixture back to use for fluorescent bulbs or want to use the ballast somewhere else. Typically, the ballast will have two screws or bolts holding it in place in the fixture, and these can be removed using a screwdriver or pair of pliers, as appropriate. You have to dispose the ballast according to the local regulations as should the old fluorescent bulbs. Because the fluorescent bulbs contain a small amount of highly-toxic mercury, they should be treated as hazardous waste and disposed of accordingly.

Once the ballast (and starter, if one was present) have been removed and the wires reconnected to complete a circuit for each bulb, replace the reflector or cover over the wiring and the area where the ballast was located, and the LED tube light bulb can be inserted in the end sockets. Unlike traditional bulbs which do not have a top or bottom, LED tube lights will have an obvious top and bottom, with metallic heat sink located on the backside of the tube and the LEDs visible under a lens on the side that will be aimed towards the area which is to be illuminated. Turn on the switch and if you have done everything properly, now you should have as good or better lighting using approximately half the electricity and lasting as long as 50,000 hours or more.

Are you looking to replace your current 50W halogen bulbs

Are you looking to replace your current 50W halogen bulbs with some of the new LED ones because you have learnt that they can help to bring your electricity bills down? If PIR flood light you are then you will need to look are replacing each one of these bulbs with an LED MR16 bulb.

However before you go out and make such a purchase there are certain things you should know. Below we take a look at just what some of these things are and, which will help to ensure that you make the right sort of purchase.

The first thing to know with regards to replacing your current halogen bulb with an LED MR16 bulb is that not all of them are compatible. You need to understand that it isn't a simple case of replacing your current halogen bulb for an LED bulb. You may find that in order to install your new bulbs you will also need to purchase an additional component such as a dimmer or driver to then use them.

Another thing you should also know with regards to these types of bulbs is that they do have thermal management issues. It is important that when installing such lights that you may find yourself having to replace the connection point within the light fitting to ensure that the temperature inside the LED MR16 bulb is kept at an acceptable level.

If the temperature level is too high or too low then of course the quality of light emitted will be badly effected. Also you need to make sure that fitting into which the bulb is being installed is one that allows heat to be dissipated easily.

Today these types of bulbs are now commercially available and certainly the major producers of light fittings and bulbs are now making such items. However be aware that each one of these companies has come up with its own particular design and may not be as effective as one would hope.

Although these companies have spent millions of dollars in designing and testing their products they still have issues with them. The biggest problem of which has been being able to create an LED MR16 bulb that can produce a very high lumen output, but is also to be found in a very compact size. Furthermore of course for these companies they also have to make sure that their lights meet certain standards. For example today any LED lights must be able to meet Energy Star requirements.

The Energy Star requirements that these lights need to meet include them have a 40 lumen/watt efficacy. Also they should be able to reach a minimum CRI (Color Rendering Index) of not less than 80. Also the LED MR16 bulb should be able to maintain 70% of its lumen output after it has been running for 25,000 hours. Also these bulbs should be able to reach a specified level of lumen maintenance that is within 0.007 on a CIE 1976 diagram after being used for 6,000 hours.

We all tend to look at utilities bills whether is gas

Maybe you own stock in the local utility and you prefer paying 10 times the amount for power.  For the rest of us, LED lighting is pretty much slam dunk due to a few factors but the biggest by far is the savings on powering your lights.  There's no better lighting technology commercially available to keep money in your pocket.  Most residences and business are in some other business...not the power or lighting business so let's break down some of terminology and show you how this directly translates into money...your money by the way.

We all tend to look at utilities bills whether is gas, electric, or water and just assume there's not much we can do about.  Hey, we can barely read the bills much less figure out what's really driving the monthly bills.  Interestingly, the utility portion of our monthly expenditure usually ranks in the top 5 line items in terms of how much it eats up.  It's a lot of money but till now, we always looked at it as a necessary evil beyond our efforts to really reduce.  If you're still burning (quite literally) incandescent and fluorescent lights, that has all changed.  Let's break down the power savings across the three different types of bulbs with just a common 60 watt light.

First, we need to set the ground rules.  We'll assume 10 cents per KWH or Kilowatt hour.  This is a measure of electricity and it essentially speaks of a thousand (the "kilo" part) watts times an hour.  It's a standard measure of electricity and one that should be on your electric bill once you become fluent in Chinese, Russian, and binary code.  The cost per KWH (10 cents in our example) can fluctuate according to State, type of user (residence versus various times of business) and overall usage.   10 cents is actually pretty low and your cost of electricity is likely higher..perhaps much higher.  Looking at our home bill, it's tiered No Sensor-AC Floodlight Suppliers by usage and a large percentage of my house's lighting (before the LED installation) was actually at a tier 3 rate or 42 cents per KWH.  That's 4 times the estimate were using so the numbers to follow are very very conservative for most people.  The second piece aside from cost per KWH is the wattage your actual lights use.  This is where LED lights shine (and shine and shine and..).  Let's look at actual numbers.

An incandescent bulb at 60 watts in our baseline since it's such a common bulb.  Any brighter or stronger bulb will only magnify the savings since increased wattage is required.  A typical CFL light bulb which is really just a less efficient alternative to LED's would probably match that wattage with 13 watts.  It would also add in some nasty phosphorous and mercury to the equation.  Now...drum roll please.  You can easily get the lumens or amount of light from and LED with 3 watts.  That's right 3 watts will match a 60 watt incandescent.  Since the electricity utility charges you based on watts used (the KWH), this directly translates into money.  An LED is almost 20 times more efficient and conversely, 20 times less taxing on your monthly budget.  Of course the LED last much longer than the other types of bulbs which offsets the higher LED cost.  Why do LED's create the same amount of light with such less power?

Incandescents and CFL's are very poor vehicles to turn electricity into lumens.  That's what we want after turn electrons into photons as efficiently as possible.  Incandescents transfer 90% of their incoming power into heat.  That's not a very good system but it was first and easiest technologically speaking.  Lights but be better served if we wanted to heat a space...not light it.  CFL's are better but only get you part of the way to what LED's do.  Again, we have heat production (although less than incandescent) and they use a chemical process of exciting certain gasses that isn't entirely efficient.  LED's basically pump electrons into photons.  There's almost no heat and very little waste in the process.  It's the most direct we have and that's why you pay less per lumen of light. 

The net effect is this.  Over a 5 year window which is the conservative life of the LED light, you can expect to save $20 annually from one light bulb change.  This is a combination of power savings and less bulb replacements.  Look, if you want to invest in a utility, buy their stock.  In the meantime, reduce the amount you send to them by 90% or more.   Don't worry...they'll still find ways to buy pet T-Rexs.

In addition, research papers have pointed out that LED lamps contain lead

Previously, relevant experts and scholars have suggested that the blue light in the illumination has a certain weighting hazard to the human retina. Recently, relevant research found that LED lighting has induced health problems, saying that people who work and live in LED white light pollution environment for a long time, the retina and iris will be damaged to varying degrees, the visual acuity drops sharply, the incidence of cataract Up to 45%. It can also cause dizziness and upset, and even symptoms such as insomnia, loss of appetite, depression, physical weakness and the like.

According to optical experts, the reflected light of mirrored building glass is stronger than that of sunlight, and its reflectivity is as high as 82% to 90%. The light is almost completely reflected, which greatly exceeds the range that the human body can bear.


In addition, research papers have pointed out that LED lamps contain lead, arsenic and dozens of other dangerous substances. White LED lamps have the least lead content, but there is still a large amount of Battery Portable floodlight nickel, a heavy metal that can trigger an allergic reaction. The level of copper found in some LED lamps may pose a threat to the environment. If accumulated in rivers and lakes, it may poison aquatic organisms.

To this end, in response to related issues, China Lighting Network reporter interviewed Li Zili, Secretary General of the Guangdong Provincial Lighting Society, to explore the deep-seated reasons why LED lighting white light was questioned to affect  human health and LED lamps were questioned to bring heavy metal pollution.


Li Zili, Secretary General of Guangdong Lighting Association


The "sin" of LED lighting affecting vision health is not all in white light

What is the harm of LED white light to human eye health? In Li Zili's view, the above research results are only appearances. He has in-depth interpretation of the research results from two aspects.


First of all, according to the international standard IEC62471:2006 "Photobiosafety of lamps and lamp systems", 1 cataract mainly causes damage from 700nm-1400nm red light to infrared light and 290nm-325nm medium wavelength ultraviolet light, generally called "infrared-induced cataract". "and "UV-induced cataract", but currently there is no infrared light in the illumination LED and there is no ultraviolet band in the middle band; 2 photoinduced keratitis is mainly caused by short-wavelength of 200nm ~ 320nm, medium-wave ultraviolet light, but currently used in LED lighting The absence of these ultraviolet rays; 3 retinal hazards mainly caused by 400-500 nm blue photochemical damage, and 400 nm to 1100 nm visible-to-infrared thermal damage of the retina, but the main effect of thermal damage of the retina must be less than 10 seconds to produce a human eye. High-temperature high-power lamps are illuminated. At present, there is basically no infrared light in the LEDs for lighting, and there is basically no high-power LED lamps used in close proximity. It can be seen that there is almost no ultraviolet light and infrared light in the LED lamps currently used for illumination, and the harm of LED white light to the human eye is mainly reflected in the "blue light" aspect.


However, many traditional lighting products, such as high-end lighting and high-power metal halide lamps used in shopping malls and stadiums, have both high-power infrared heat and "blue light", as well as "long-wave, medium-wave, and even short-wave ultraviolet rays." Even the incandescent lamps that people are most accustomed to have a large amount of infrared rays, a small amount of ultraviolet rays and blue light. White light can be decomposed into red orange, yellow, green, blue, and purple. It can also be composed of red, green, and blue primary colors. Therefore, the Blu-ray is necessarily present in all lighting products.


Secondly, sunlight is the presence of a large number of high-intensity infrared, ultraviolet and blue light. Strong sunlight, its ground illumination is about people learning to read a hundred times the illumination specifications, the sun in the blue spectral power is greatest. Therefore, LED white to blue harm the retina of the human eye need not be scared, after all these years of controversy and improvements, the basic measurement without the risk of second-class RG2 LED lamps, these lamps RG2 long look at the longer distance is light It's perfectly fine, and it will damage the retina when it is close to the light for a long time. In contrast, the men looked directly looking up the sun at noon than 1 seconds may cause damage to the retina. From this point of view, the risk of sunlight reflected from the specular wall of the building's curtain wall is relatively high (especially for children and young children who cannot avoid glare) because people do not need to look up too much and their eyes may look To strong reflected light. Thus, LED lamps and LED lamps is relatively very safe.


In general, to solve the human eye health problems caused by LED white light, we can only return to find out how to suppress the blue light damage to the human eye.


LED lamps can not be "full" responsibility for heavy metal pollution


For LED lamps that are suspected of causing heavy metal pollution, Li Zili believes that it is not only LED lamps that contain heavy metals. Many daily consumer products or their production processes use a lot of heavy metal elements such as nickel and copper. In the past, traditional lighting products also used heavy metal elements such as nickel and copper. For example, fluorescent wires used in a large number of conductive wires were iron-plated nickel. A large number of light sources are copper-plated, copper-plated iron wire, nickel-plated copper wire, nickel-plated iron wire, nickel-plated iron wire, etc. Most of the E27 and E14 lamp caps of the energy-saving lamp are made of heavy metal nickel such as iron-plated nickel.

At the same time, Li Zili also pointed out that it is not a good thing to use these heavy metal materials in the LED containment and production process. Among them, nickel is the most common contact with allergic metals. Therefore, to reduce the harm of nickel and other heavy metals to the human body and the environment, In the process of dismantling and recycling LED products, it is necessary to do a good job in environmental protection.

Why LED lights are repeatedly questioned

White light is a common kind of light. Traditional fluorescent tubes and energy-saving lamps are also white lighting, but their health problems for the human eye are not very prominent. Why do LED lamps have such a big impact on human eye health? Even with the heavy metal pollution that many traditional lighting fixtures have, LED lamps will be “single out” in this respect. In response to the above questions, Li Zili believes that there are The following reasons:


1) The advantages of LED lighting compared to traditional lighting are very obvious, but compared with traditional lighting products, LED still has some defects. For example, 1LED has a small light-emitting area. In the early days, many LED lamps did not undergo diffused light processing, resulting in high brightness and glare; 2 LED luminosity and chromaticity spatial distribution were uneven, resulting in uneven light and color of the illuminated surface; 3 even in the same color gamut 2 LEDs, for example, even if they meet the standard requirements in the 7-step color gamut, but the color difference between them may also be obvious; in traditional lighting products, except for metal halide lamps, other lights do not appear; 4 At the same color temperature, the LED is theoretically and practically more risky than the blue light hazard of traditional lighting products. Especially in the early stage of LED development, LED has low light efficiency and high price. Many LED lighting products use high color temperature LED light-emitting diodes with higher light efficiency than low color temperature LEDs, which is another reason for high brightness and glare.


2) Human cognition and adaptability. The advantages of LED lighting compared with traditional lighting are very obvious, and the technology is developing very fast. The process of replacing traditional lighting with LED lighting is very fast. The difference between LED lighting and traditional lighting does make some people feel uncomfortable for a short time, especially in the early stage of LED lighting development. But after a while, most people have become accustomed to adapt.


3) Because traditional lighting is not a high-level industry, but it involves many people, it is not very concerned by technical personnel. Most of the experts engaged in high-tech do not have the practical experience of traditional lighting, and the technicians engaged in traditional lighting also recognize LEDs. Insufficient knowledge, both of which make it difficult to fully and accurately compare LEDs with traditional lighting, and it is difficult to fully understand the shortcomings of LEDs.


4) The early development of LED is still not in place. For example, the most important light efficiency indicators can not reflect higher than traditional lighting. Some of the LED lighting trends are not well understood. Some traditional lighting companies that are in a wait-and-see state may be in their own interests. Various occasions have made some comments that are not conducive to LED, which has produced a profound misleading to the public. At the same time, because there are no standards for initial LEDs, it is quite confusing, and many LED lighting products do have many problems.


Based on the above interpretation, LEDs are indispensable for the lighting industry and society. However, Li Zili also pointed out that the human health problems that may be induced by LED lighting are not exclusive. The traditional lighting industry and products also exist, and some even more serious. With the advancement of LED lighting technology, all problems will be solved.
