Whether you are cordoning off sections of a tattoo parlor, healthcare facility, photography studio, laboratory, class room or a home, curtain tracking has become an easily accessible tool. Selection and installation of curtains and curtain tracking is not rocket science, but here are some pointers to smooth the process.

The first step is choosing a curtain. You need to ask yourself what you want your curtain to do. If it is needed it to block light, then a blackout fabric should be chosen. If it must meet state and federal commercial fire codes, then mesh top curtains are necessary to allow sprinkler systems to adequately protect their environment. Quality cubicle and hospital curtains are made with inherently fire retardant materials that are durable, safe, and last throughout the lifetime of the cubicle curtain. There are many colors and styles of fabrics to choose from; including solid colors, striped, textured, patterned and more.

Once a style is determined, calculate the height and length of the curtain necessary to cover the intended space. The length should generally be 15% wider than the length to be covered. For a more ruffled look, add 30% to the length. For example: you require 220″ of length to cover your space. You would then multiply 220″ x .15 and come up with 33″; add the 33″ to the original 220″ and you will need to order a length of 253″.

To establish the height of the curtain there are three measurements needed to be determined. Begin by measuring the height from the floor to the ceiling. For this example let’s start with a 10 foot ceiling which is 120 inches in height. Next measure the height of the carrier and curtain tracking; this is usually 3″-4″ combined. The third measurement to determine is the open space wanted below the bottom of the curtain; 12″-18″ is typical.

Take the ceiling height of 120″ and subtract 12″ for bottom clearance and 4″ for tracking and carriers and this leaves a final curtain height of 104″. Typical curtain sizes range from 72″ to 234″ wide and 84″ to 108″ long. Cubicle curtains can be made to order and customized in most cases. Healthcare facilities often have building and fire codes which must be met; check with an administrator before proceeding.

Quality curtain tracking is made of 16 gauge extruded aluminum and is typically sold in eight foot lengths. If shorter lengths are required, tracking may be easily cut down with a hacksaw. Curves pre-bent to 45 deg. and 90 deg. are available for applications requiring the curtain to bend around a room; curves are 2 feet by 2 feet and bent at a 12 inch radius.

Curtain tracking can be attached to solid or false/drop down ceilings using screws or clips. Attaching the tracking to a solid ceiling requires the use of screws; screw directly into ceiling studs whenever possible. Holes will need to be drilled into the tracking at each attaching point. It is not always possible to screw into a stud. When this occurs, the use of an anchor is necessary. An anchor is pressed into a pre-drilled hole. As a screw is inserted into the anchor; the anchor expands and grabs firmly to the ceiling. Drop down/false ceilings require clips which are attached to the ceiling grid. There is a hole tapped into each clip that accepts a screw from the curtain tracking. These clips should be placed every 30″.

Suspension tubing may be used with high ceilings or if existing obstructions prevent the curtain tracking from being mounted directly to the ceiling. Suspension tubing is available in 8 foot lengths and made with 7/8″ O.D. hollow aluminum tubing. Suspension tubing can be attached directly to solid ceilings with a ceiling flange or via ceiling clips to a drop down/false ceiling. A screw insert is then placed in the bottom of the suspension tubing allowing the curtain tracking to be attached. Suspension tubing should be placed every six feet and the tracking ends can be attached to a wall with a nylon wall bracket.

Ceiling Curtain

Anodized aluminum splicing clamps join multiple pieces of tracking to ensure proper alignment of the channels. This will allow the carriers/rollers to move freely from one piece of tracking to the next. Clean and smooth the ends of each piece of track before assembly; burrs may cause the carriers/rollers to hang up.

An end-stop should be placed at both ends of the curtain tracking setup. Curtain tracking end-stops are used to prevent curtain carriers from slipping out. One end should contain a snap out fitting to allow for easy installation and replacement of curtain carriers. Snap out fittings sit inside an end-stop and are easily removed. Removal is necessary to install or replace your curtain carriers without removing the curtain tracking from the ceiling.

Various specialty brackets allow for multiple ceiling track configurations. T-brackets connect a perpendicular section of tracking part way along an existing section of tracking. Cross brackets subdivide a room into 4 or more separate sections depending on the size of your room and the size of your tracking layout.

Once the tracking layout is finalized, then determine the number of carriers or rollers needed. Carriers are just that, they carry the curtain along the tracking. The standard style consists of a nylon block and wheels with a swiveling chain and hook attached. A breakaway version is available which acts contrary to its name; the carrier does not break, it flexes. This allows the curtain to detach from the carrier rather than damage the curtain or carrier. Curtain carriers should be spaced every 6″ on the curtain. If your curtain is 242″ in length, you will want to have 41 carriers.

Drop chains and PVC drop strips are available for use when ventilation space is required and a mesh top curtain is not an option. A drop chain is 18″ long with custom lengths available; it is constructed of nickel-plated steel. A PVC drop strip is 18″ long with a hole on top which slips over the curtain carrier; a plated hook at the bottom connects to the cubicle curtain.

We often dream about having a big house. But actually, many of us can only afford to buy a small house. In spite of its house, it is our beloved house and we really want it to be as beautiful and comfortable as possible. So we try every effort to design our own house and add beauty to it.

The key to a functional and comfortable living room rests in the choice of illumination in the room. In the 1980s and 1990s, it was common to see lamps that were designed to be purchased as a three part set. If you have some hard-wired lighting but feel like table lamps and floor lamps would add a bit of subtle ambiance to the room, then check out some practical ideas. Table lamps and floor lamps offer something that existing light sources don’t have, versatility. You can divulge in lamp variations and still keep harmony and unity in your living room. You can place a floor lamp or a table lamp in a living room and dramatically improve the mood and tone of the room. Practice these simple suggestions for a living room that has harmonizing illumination. In addition, stacking a table lamp will add more height to the table and increase the illuminating effects in the room.

Each of the light fixtures was made out of exactly the same materials, and was designed in the exact same way. The only difference was the height of the lamp itself. This overly coordinating lamp trend has come and gone, and a newer more varied and flexible decorative motif has emerged. For example, a brushed nickel floor lamp will complement a solid black table lamp if you choose contemporary lampshades for each. The lamp variations will add a sense of dynamic appeal to your living space. They can be plain and simple or ornately designed depending on your decorative needs. In addition, the wattage and type of light bulb that you choose will have a great impact on the illumination in the living room. The key to a functional and comfortable living room rests in the choice of illumination for the room.

Table lamps don’t have to rest directly on a table to serve the purpose they were designed for. Lampshades designs are an important design element in modern living rooms because they add color, texture, and pattern to the room. You can even use a stacked table lamp in place of a floor lamp if the living area is better suited for a tall table lamp. Illumination in a living room is not just about the lamp itself. It is also about the lampshade and bulb that you are using with the lamp. Lamp variations, dimensional attributes, and lampshade design can all have a positive influence on the mood and feel in the room. You can stack books, magazines, or simple flat accessories on a table, and then place the table lamp on top of those items. This will actually add a greater sense of dimension to the table space itself.

Don’t be frustrated about the size of your house. You can still own a beautiful, impressive, and comfortable house with proper lamps for living room. Good luck and enjoy your small but beautiful house!

Do you want to create an LED sign by yourself? It is very interesting and money-saving. Come on, just have a try. Are you ready? Here are some instructions which may offer you some help.

Install the resistors on the back of the circuit board. Outside of being used in jumbo televisions, remote controls, flashlights and digital clocks, you can purchase LED lights in bulk to create a sign that is customized and gift-able. Use the smaller circuit board if you will be doing slim characters such as the number “1″ or letter “I.” Install the resistors according to the directions or by soldering them into place so they do not move or wiggle. LED signs are affordable to make and can be a worthwhile project for someone interested in electronics. Mark with a black pen where you want to position your LED lights to spell out your desired word or display a picture.

Crop the leads of the resistors using a strong pair of pliers. LED stands for Light Emitting Diode, and most modern-day electronics depend upon LED technology to function. Do this only after all resistors are soldered in, and before any LEDs are installed. This makes them much more durable and provides them with a longer life expectancy.

Install the LED lights in your desired position. A chamfer on the LED will show you which way they should be installed. Your board size should be able to hold 3 millimeters to 12 millimeter LEDs. LED lights that are used to make a sign are not lit by filaments like a standard light bulb, and are covered in plastic instead of glass. Using an inexpensive LED tester will help you ensure your LED lights are working and are compatible with your board. LEDs are installed with a pin fastener that usually comes with the lights themselves.

There is no doubt that it is not an easy job to create an LED sign, especially an LED sign of high quality. Nevertheless, practice makes perfect. Don’t be frustrated and just have fun!

Have you ever had any experience of making an LED pen by yourself? If you know something about making an LED pen, you need not ask someone else for help and thus it is money-saving. Come on, just have a try. Are you ready? Here are some instructions which may offer you some help.

Remove the cap from your flat highlighter pen. Light emitting diodes (LEDs) are wonders of modern science, creating an impressive amount of light with a relatively small amount of electricity. Use a pair of needle-nose pliers to remove the end cap and ink rolls. There should be a larger ink roll inside the main pen body and another smaller roll extending from the pen tip. 10W LED can last for years without replacement, making them an increasing popular alternative to more temporary light sources.

Place your LED along the edge of your coin battery so that the terminals straddle either side of the battery. When pressed against the battery, the LED should light up. LED pens, featuring a bright LED in place of the ink tip, are useful due to their portability and small size, making them the darlings of electricians and automobile mechanics. If it does not, rotate the battery 180 degrees.

Drop the glowing LED into the end of your highlighter pen. Wrap a small piece of electrical tape around the LED terminals and coin battery. Remove the end cap and separate the battery from the LED when you are not using your new pen. The flat sides of the pen allow the wide coin battery to slide in.

The LED will protrude from the tip of the pen, offering its bright glow in the direction of your choosing. Shake your highlighter. If the LED and battery bundle moves around inside your pen, shove a few sheets of tissue into the end to hold everything in place. Use a more powerful coin battery to make your LED grow even brighter. Place the end cap on your highlighter when your pen is not in use.

There is no doubt that it is not an easy job to make an LED pen, especially an LED pen of high quality. Nevertheless, practice makes perfect. Don’t be frustrated and just have fun!

Automotive bulb? What is that? What is the function, purpose, type, size, feature of an automotive LED light? Today I’ll introduce to you some basic information about automotive bulb.

There are four main types of automotive bulbs that are used in an automobile. Depending on your vehicle, headlights can be a sealed beam or a bulb type. There are standard bulbs that are most often used. Cool blue and blue vision versions produce a whiter light than a standard bulb. Both fog lights that mount on top of a truck as an aftermarket item and the standard type on the bottom of a car operate on halogen bulbs.

These include headlights, fog lights, mini bulbs and decorative lighting. In each type, there are variations, such as color, size and brightness, that are determined by the design of the bulbs and the intended purpose. The sealed beam requires you to buy a new entire headlight for replacement, which includes the bulb outside as well as the glass and metal casing. Mini bulbs are shorter in length than other bulbs and are generally not used as often as other bulbs. This type of bulbs has uses for turn signals, cornering lights and running lights.

The bulb type has six subcategories of bulbs within it. Taillights and stoplights use mini bulbs to operate. Sequenced lights that blink from one end to the other and then become solid or remain in a sequence are examples of strobe bulbs and are in wide use on side mirrors for blinkers and for additional brake lights. Running boards and step rails use this type of lighting that comes on when the vehicle doors open to ensure safe footing when getting in or out of a vehicle. Undercarriage lights are available in many colors to create colored light underneath a vehicle.

There are also xenon bulbs that produce 30 percent brighter light, and the xenon ultra produces 50 percent brighter light than standard bulbs. Argon and krypton make up a long life bulb, which should last 50 percent longer than a standard bulb. There is a large variety of applications for specialty or decorative bulbs on an automobile to perform various functions. Neon and LED lights are useful on side view mirrors as additional blinkers and in the rear of vehicles as additional stop indicators or brake lights.

To know something about automotive bulb can give us a general picture of it and can, to some degree, help us better use automotive bulb if necessary.

Since LED flashlights are widely used in different fields, they can also be used in home. A proper      can bring you a lot of convenience. But how to select a proper LED flashlight is not that easy. Here are some tips which may give you some advice.

Check out the battery life for each LED flashlight in which you are comparing. There are many activities and situations where a quality flashlight might be helpful or even necessary. LED flashlights tend to have multiple light settings, such as low, medium and high, so you should compare the battery life at each of these settings. When considering which flashlight to purchase, one of the main factors should be energy efficiency. The LED flashlight packaging or product description should include a battery life chart.

Pay attention to the indicated effective range for each LED flashlight. The more efficient a flashlight is, the more dependable it is because the batteries will last much longer than inefficient models. Again, this could vary depending on the light setting. Knowing what activity for which you’ll be primarily using the flashlight can help you determine the minimum indicated effective range that you will need. LED flashlights, for example, are very efficient and the batteries tend to last much longer than other types of flashlights, such as those that use incandescent bulbs. For example, if you plan to use the flashlight while camping, you will most likely be looking for the longest range you can find so that you can see in front of you while walking through the woods.

Research the pros and cons of replaceable versus rechargeable battery LED flashlights. When deciding which LED flashlight to choose, it’s important to compare all of your options. The rechargeable battery models tend to cost more and the batteries can be harder to come by. Some consumers prefer putting the extra money into a more powerful LED flashlight that takes standard replaceable batteries that are easier to find. Shake flashlights are also a possibility.

Since you have known some features of LED flashlights from the abovementioned, it becomes much easier for you to compare LED flashlights and pick up the most appropriate one.

As we all know, LED lighting is used in different fields. Today, we will explore how to disassemble LED flashlights together.

Put the newspaper down on a work surface. An LED flashlight is different because it uses an LED and not an incandescent bulb to supply the light. Remove the battery compartment cap from the LED flashlight. Remove the batteries from the battery compartment and put them and the battery compartment cap aside. Electronic circuits inside the LED flashlight help regulate the power to the LED so that the current does not cause an overload.

Hold the back end of the LED flashlight with one hand. Grab the front end of the LED flashlight with the needle-nose pliers. Disassembling an LED flashlight so that the parts can be used in something like a science project requires the use of a soldering iron to separate the LED from the circuitry. Twist the needle-nose pliers until there is a crack in the seam between the front and back parts of the LED flashlight. Put the needle-nose pliers down. Grab the front end of the LED flashlight with the free hand and twist the front until it separates from the back. It should only be done by someone with a steady hand who feels comfortable using a soldering iron.

Pull the LED assembly carefully from out of the front half of the LED flashlight. Put the LED assembly down on the newspaper. Unscrew the reflector from the front half of the LED flashlight. Remove the reflector and put it down on the newspaper. Put the back half of the LED flashlight down on the newspaper. Remove the reflector ring surrounding the LED bulb with the tweezers and put it down on the newspaper.

Hold down the LED assembly with one hand while gripping the sides of the LED bulb with the tweezers. Remove the soldering iron as soon as the solder on the contact starts to bubble. Pull the LED bulb from off the LED assembly using the tweezers. Put the LED bulb down on the newspaper.

Got it? Hope that you can really learn something about how to disassemble LED flashlights from this article. Enjoy yourself!

LED light or Fluorescent tube light? You may be troubled by the question which one is more suitable to you. Today, I will make a comparison between LED tube light and Fluorescent tube light. Hope that this will give you some inspiration.

Light emitting diode (LED) and fluorescent light bulbs are considered energy-efficient lighting. A typical LED only draws between 2 to 10 watts of power to produce light. A 6- to 7-watt LED produces about the same level of light output as a 100-watt incandescent bulb. A 22-watt fluorescent lamp produces the same levels of light output as a 100-watt incandescent.

Perhaps the only obstacle in the way of LED’s widespread use is production costs. Both produce generous amounts of light for the wattage of power they require to operate. Each type of light bulb comes with certain advantages and disadvantages. It costs more to produce LEDs than it does to produce most other types of light bulbs, including fluorescent bulbs. Although they do not demand the same production costs as LEDs, fluorescent bulbs are still more expensive to produce than incandescent.

Because of current technological limitations, the size of an individual LED is rather small. Both types of light bulbs have a high initial cost, but this is offset by the amount of electricity they save the consumer in the long run. They are often clustered together for many applications. The life of a fluorescent bulb can be significantly shortened if it is continually turned on and off.

A typical fluorescent light bulb can last around 10 times as long as a typical incandescent bulb. LEDs are some of the longest-lasting light bulbs on the market. LEDs are less prone to damage by being dropped or jarred because they have no filament. They are capable of lasting for up to 10 times as long as fluorescent light bulbs.

Unlike almost every light bulb on the market, LEDs contain no traces of mercury, a toxic element. Fluorescents, on the other hand, depend on their mercury content to function properly. One of the largest benefits to LED lighting is that they run cool; very little energy is given off by LEDs in the form of heat. A fluorescent light bulb can contain around 5 mg of mercury.

In brief, there are some similarities and differences between LED light and Fluorescent tube light. Think twice before you make the conclusion. Good luck!

We often dream about having a big house with a comfortable living room. But actually, many of us can only afford to buy a small house. In spite of its house, it is our beloved house and we really want it to be as beautiful and comfortable as possible. So we try every effort to design our own house and add beauty to it. Here are some tips about how to enhance a living room’s decor using lighting.

Every room has a main source of light and in a living room; floor lamps are often the lighting source of choice. Lighting is an important part of interior design, especially when decorating one of the main living spaces of a house: the living room. For softer lighting, use floor lamps that point upward or that disperses lighting more evenly. Use a floor lamp that utilizes a drum lamp shade, as these types of lighting won’t create the harsher light that occurs with downward-pointed lamps.
The right lighting choices can make or break the design of a well-dressed living room. In the living room, table lamps can be used as task lighting. However, it can also enhance or completely alter a person’s mood. In a living room, it is important to provide adequate lighting that allows for every day tasks to be accomplished as well as lighting that highlights certain aspects of the room.

Recessed lighting can also be an important part of lighting in a living room. Different types of recessed lighting can be used in different areas. Choose table lamps that produce adequate light for the tasks that are most often performed, whether it be reading a book or working on a book report for school. Directional recessed lighting can be used to highlight a painting, while traditional recessed lights can be used over a coffee table or to highlight the corners of the living room.

Though different wattages may be required for different light fixtures, the bulb colors should be uniform to prevent any unusual discoloration of light in the room. Use all clear or all opaque light bulbs. When purchasing light bulbs, you should use bulb colors that are the same. Track lighting is an alternative option for recessed lighting and, like recessed lighting, can be used over paintings, bookshelves or the media stand. Both options can also be used to highlight architecture elements of the living room, such as a fireplace or columns.

In summary, you should consider different factors while you are designing your living room’s lighting. Only after this can you work out a lighting plan which suits your living room best.
