Lighting is a very important part of decorating a home. It adds to the warmth and atmosphere of a room. Making a decision on what type of lighting to use is crucial as this affects the decor of a room as well as the house.
Table lamps are still favored by many people. There are so many styles these days that they can never really become unpopular. They add a certain charm to a room apart from light and glow. Decorating with this type of light is one of the best ways to lighten up a room. They radiate more illumination as compared to table lamps and cause less strain to the eyes.
Table lamps come in many different styles to suit any taste and any type of decor used in a room. They are decorative pieces and come in varying sizes and materials. Apart from European, wrought iron, sculptured, etc. they also come in mission and contemporary styles which people use more as they go with anything.
Another type of lighting used in homes is ceiling lights. This type of lighting is preferred to ceiling lights by many people. It is simple, functional and goes with any decor. They are less flashy compared to ceiling lights like chandeliers. They are there in the background, creating an ambiance for the room in style.
Table lamps can be fitted into a variety of interior designs as they are versatile and are available in an array of styles and designs. Whatever the preference of the home-owner is-classic or modern, there are many shapes, colors and materials to choose from. They can be decorative and also can be used as down-lighters or up-lighters. They can create interesting patterns of light on the walls.
In today's market, lighting companies compete with each other for the consumer's attention. An extensive range of lights for different parts of the house, both indoors and outdoors, are offered by these brands. Special offers and discounts are also offered by these companies on their products. Nowadays there are numerous on-line stores where you can find a wide array of lights and lighting fixtures. Brands like Flos, Foscarini, Artemide, just to name a few, are all available on-line.
These brands can also be found in exclusive home decor stores. However many people like to shop on-line as they are able to save money with the competitive prices that are available on-line.

If you are thinking of giving a facelift to your home by adding some outdoor lighting fixtures on the entryway / patio or brightening up the interior decor with a wall chandelier or ceiling fan, then you need to hire electrical contractors from a reliable company. However small the task may seem, trying to do it on your own may result in disaster. If you are in a big city like Los Angeles, Chicago, Illinois or New York, then you can get a large number of contractors in the local directory or yellow page.
Apart from the usual wiring or installing of electrical fixture, an electrician also sets up wiring for appliances like dryer, oven, microwave, and ceiling fan. He can replace flood motion light and circuit breakers, does spa or hot tub wiring, install dedicated circuits, grounding, emergency lighting, ballast replacement, computer circuits, generators, and many such other things.
However, before hiring electricians in Chicago or any other city, you need to ensure whether you have chosen the right person for your home. You can ask for local references from your neighbors or friends, check the credibility of the company with BBB or Better Business Bureau, and once you have short listed the companies, you can pay them a visit or call them up and ask certain questions like - how long the company has been in business, are the electricians licensed, certified, insured, and bonded; can the company give at least three to five references, and whether the company would give a written guarantee. If all the answers are satisfactory, you can go ahead with that company.
You can save time by planning to combine all the electrical projects, like computer wiring, installing lighting fixtures, having some extra outlets, and so on. You need to make a specific list of your needs and can even mark the wall or ceiling with a pencil. This will not only save your time and energy, but the electric contractor will also have a better understanding of your requirement and can suggest changes immediately, if needed.
After this, you need to sit with the contractor for scheduling an estimate. You can discuss with him about your affordability to spend for the total project, including labor and electrical materials. Some of the common tools used by electricians include drills, saws, small power augers, guns, and so on. The electrical contractors also offer high-end solution regarding the wiring. They check the wiring with the help of ohmmeter or voltmeter. You need to check out with the electrician whether he is going to charge anything extra toward these tools. As, labor and material cost may fluctuate from time to time, you need to get the estimate and start work within a very short period of time. If you opt for a long term contract with the electrical company, they will also send electricians from time to time and check on the electrical appliances of your home.
Another benefit to hire electrical contractors rather than doing the job on your own is, once you have a licensed professional do the inspection, the property value would certainly have an added advantage at the time of selling and bring you more money. So, start to look for reliable and licensed electricians in Chicago and give your home a new look.

Back to 3 or 4 years ago, if someone talked about LED tubes, we may probably have no idea what it is about. But now, when we look around, we could probably see that LED light tubes have become a very hot topic and have been becoming more and more popular year by year or even day by day. The traditional fluorescent lights are widely and typically used in different lighting applications such as industrial lighting, warehouse lighting, commercial lighting, office lighting and residential lighting etc. But nowadays, it seems the moment to consider about replacing them with LED light tubes.LED or referred to as Light Emitting Diode is environment friendly as they generate light by the movement of electrons in the diode. Comparing with LED, florescent lights waste most of energy to produce heat which are definitely no good to our environment. A typical LED light tube may include hundreds of LEDs. The actual number of LEDs depends on the size of the tube or the illumination requirements.There area a great deal of positive aspects that drive people to try and make use of tube LEDs. For example:- Can you imagine how much heat a fluorescent tube light can produce? Have you heard about the complaint made by those people who have to sit or work underneath or near fluorescent tube lights - haven't mentioned that some of them claimed to suffer from frequent head aches. Not like the conventional fluorescent lights LEDs will not produce much of heat and they would not cause people any head aches. LED lights can be installed wherever you want them to be, living rooms, bedrooms, halls, buses, trains, boats, cabinets, etc. And of course, you may have probably notice there are some Christmas lights and curtain lights that are made of LED lights.- LED tubes consume 60-70% less energy when in comparison with the fluorescent tubes. Typically, a 20W fluorescent tube can be replaced by a 8-10W LED tube; a 40W fluorescent tube can be replace by a 15-18W LED tube; a 60W fluorescent tube can be replaced by a 24-26W tube LED. And please keep in mind that if taking the ballast and starter into account, the tube LEDs can save even more energy as unlike fluorescent tubes, LED light tubes do not need any ballast and starter.- LED tubes are available in different sizes and colors (in a more technical way of description, it means color temperature). Currently, LED tubes follow the traditional design of traditional fluorescent tubes (T5, T10, T10, T12 etc). The reason for that is to allow direct replacement of the existing fluorescents without extra retrofit cost by replacing the whole lighting fitting. As a result, the commonly obtainable sizes of LED tubes (take T8 and T10 for example) are 2 feet (600mm), 3 feet (600mm), 4 feet (1200mm) and 5 feet (1500mm) and 8 feet (2400mm). Another advantage it should be looked at is the diverse colors that LED lights can produce. Back in the fluorescent tube ages, the light color of a fluorescent tube can not be chosen. But now, with LED fluorescent tubes, the light color can be cold white, pure white, natural white, warm white, red, green, blue, yellow etc, extremely flexible and user-friendly.- LEDs have much longer lifespan when compared with other lights. Theoretically LEDs' lifespan can be as long as 50,000 to 100,000 hours. Of course, when it comes to a lighting fixture, the lifespan is not only about the LEDs, but also related to all other electronic components of the lighting fixture. However, this is the way how LED tubes can help to save your maintenance bills for failed lights replacement.Despite the fact that there is variety of advantage of LED tube replacement, consumers tend to concern about the downsides. Below would be some of the most concerned drawbacks of LED light tubes:- One of the major problems (and probably the biggest one) that bother the consumers is its price. LED tube lights are much more costly when in comparison with the fluorescent tubes and incandescent bulbs. The market prices normally vary from to 0. However, considering the LED tubes can work for an prolonged time, the cost is acceptable, especially to those commercial applications that need long-time running.- Retrofit work could be another issue which is concerned, as you may need to reset the electrical configuration in order to let the tubes work properly. The conventional fluorescent tubes require ballasts and starters which are not needed for the LED tubes. Therefore, ballasts and starters will be removed when installing LED tubes. This means a little extra rewiring work.To summarize, the pros of utilizing LED tubes are considerably much more when compared with its cons. Its worth to have a try of tube LED replacement.

Daylight harvesting is probably the most over looked aspect of energy saving using lighting controls. Sensor Switch offers a wide variety of Daylight Harnessing Sensors and Solutions suitable for a stand alone or integratable environment. Studies have shown that a daylight harvesting with dimming can generate about 70% savings for the end user, which justifiably reduce the pay back calculations for any investment made on these systems.
Automatic Dimming Control Photocell - Ceiling Mount, Low OR LINE Voltage
These sensors provide continuous control of dimmable ballasts for daylight harvesting applications. Ideal for public spaces with windows like vestibules, corridors, or bathrooms; the CM ADC works by monitoring daylight conditions in a room, then controlling a 0-10 VDC dimmable ballast so as to insure that adequate lighting levels are maintained.
This particular sensor is used for dimming the lights by monitoring daylight conditions in a room and then controlling the lighting so as to insure that adequate lighting levels are maintained. The low voltage sensor operates on a 24VDC supply through a power pack, which enables a 20Amp workload to be controlled. The Lux threshold can be conveniently programmed via push buttons or via the automatic set point push button where the sensor records the desired lux levels prevailing at the time of programming. This is known as the Digital Set point programming feature.
The Sensors are available as a Ceiling Mount Recessed, Ceiling Mount Non Recessed and a Fixture Mount where access to the ceiling is limited.
LIGHT LEVEL SET POINT
The sensor functions by comparing the amount of daylight available with a defined acceptable lighting level. This threshold,called the "set-point", is utilized in all daylight harvesting lighting control decisions. The sensor can find its optimum set point via the Automatic Set-Point Programming mode. In this mode, the sensor takes light readings at different dim settings and then sets the minimum light level to be the amount contributed by the artificial lights being controlled. It is assumed that the space is properly lit by design, however, if this is not the case the set point may be easily adjusted to the occupant's preference. All modes and settings are entered digitally via a push button sequence. Once programmed, the exact value of the set point (in foot candles) can be read out from the sensor via a series of LED flashes.
DIGITAL SET-POINT CONTROL
Each sensor contains a microcontroller that enables the user to engage the Automatic Set-Point Programming mode or tomanually set / adjust the set point. The manual process involves calculating and inputting the exact foot-candle value of thedesired set point into the sensor. It is important to note that the set point is the light level required at the face of the sensor and that this value will be much different than the level required at a work surface. Typically, light levels at the ceiling are 3to 5 times less than the work surface. For example, if 50 fc is desired at the work surface, the sensor should be set at 10fc. For best results, measure the levels at both locations using a foot-candle meter before programming the set point.
AUTOMATIC CONTROL OPERATION
The sensor controls a 0-10 VDC dimmable ballast to achieve maximum daylight harvesting while maintaining a minimum light level referred to as the "set-point". When no daylight is available, the sensor will allow the dimmable ballast to operateat its full bright level (10 VDC). As daylight increases and begins to contribute to theoverall light level of the room, ADC feature starts the ballast proportionally. At the point when sufficient daylight is present to maintain the set point without any contribution from the lights, the sensor will hold the ballast at its full dim setting (0VDC). When daylight levels fall below the set point again, the Automatic Control will start reducing the dim level(increasing the brightness) in order to increase the overall light level. Finally, at the point when all daylight contribution is gone, the ballast will again be at its full bright level (10 VDC). With dimming control sensors, the set point can be easily adjusted after it has been initially programmed (via either the Automatic orManual process) using the Incremental control feature that steps the brightness setting (voltage) up or down 10% (1 VDC)and adjusts the set-point accordingly.

43 Home Energy Saving Tips
No-Cost or Low-Cost:
1. Lower your thermostat at night and whenever the house is unoccupied. Close off and don't heat unoccupied rooms (unless you have a heat pump). If you consistently set your thermostat back at night 10 degrees Fahrenheit, you may reduce your heating bill by 10-20 percent.
2. Lower the thermostat and dress warmer. As little as 1 to 3 degrees (F) makes a noteworthy difference in energy consumption.
3. Lower the temperature on your electric water heater to 120 (F) degrees. Turn it off when leaving for extended periods of time. Electric water heaters can be set on timers; gas heaters must be set manually.
4. Set refrigerator temperatures between 37 and 40 degrees (F). Clean the coils. Keep the refrigerator stocked; it takes more energy to cool an empty refrigerator.
5. Consider replacing your older model refrigerator, especially if older than 10 years. Older models can often use over 3 times the energy of newer models.
6. Wash full loads of dishes and air dry.
7. When washing clothes, use warm or cold water and rinse with cold. Air dry clothes, but not indoors as this creates unwanted mold and moisture problems.
8. Shut off lights, computers and other electronic appliances when you're not using them. Many computer monitors have a sleep mode setting which, when activated, greatly reduces energy consumption.
9. Always use the bathroom or kitchen exhaust fans while showering or cooking and baking to avoid potential moisture problems.
10. Use a microwave or toaster oven for smaller items.
11. Install a low-flow showerhead. Showers use less hot water than baths; also consider takingshorter showers.
12. Close your fireplace damper and seal the opening shut when not in use.
13. During the heating season, open south-facing window coverings (e.g. drapes, blinds, etc.)
14. during the day. Close all window coverings at night to keep the heat in.
15. Install foam gaskets behind electric-outlet and switch-plate covers.
16. Examine and adjust, if necessary, weather stripping, door sweeps, and thresholds.
17. _ Install an automatic setback thermostat that adjusts room temperature according to your daily schedule. If you have a heat pump, be certain to use a special thermostat designed specifically for heat pumps.
Steps that cost more, but pay for themselves in two years or less:
18. _ Install do-it-yourself weather stripping and caulking toseal air leaks. Seal all perimeter wall penetrations and ceiling and floor penetrations to stop all air movement between heated and unheated spaces.
19. _ Install do-it-yourself storm windows that cost less than /sq.ft. such as flexible vinyl glazing.
20. _ Use motion sensors or timers for outdoor lighting. You'll still have security and save energy.
21. _ Replace incandescent light bulbs in common areas (where lights are on most of the time) with compact fluorescent lamps (CFLs). They use about a quarter of
22. the energy.
23. _ Replace the halogen torchiere floor lamp with a CFL model. They're safer, use 70 percent less electricity and produce as much, if not more, light.
24. _ Tune up the furnace annually.
25. _ Replace furnace filters. The dirtier they are, the harder the fan furnace works. Clean filters are essential for heat pumps – airflow is critical and can add years to the life of your heat pump.
26. _ Add water heater tank and hot water pipe insulation especially if in an unheated space. Don't cover the thermostat or, for natural gas models, the air inlets.
27. _ Install a sheet metal fireplace cover, especially if the flue damper does not fit tightly.
Home energy improvements that pay for themselves in two to five years:
28. Increase attic insulation to R-38 (the current requirement for new homes).
29. _ Insulate floors over unheated spaces to R-19.
30. _ Insulate and seal ducts in attics, crawl spaces, garages and other unheated areas-potential big energy savings!!
31. _ Install do-it-yourself storm windows that cost less than /sq.ft. such as rigid acrylic glazing.
32. _ Perform low-cost fireplace modifications, such as fluetop damper or inexpensive glass doors.
Home improvements that take more than five years to pay for themselves:
33. When it is time to replace a home appliance, purchase an energy-efficient model. These appliances cost more initially, but you will save both money and energy over its entire life. An appliance that is cheaper to purchase will have higher operating costs, and savings you'll accumulate from using an EnergyStar appliance will be substantial.

Whenever a brand new item is launched, we can never deny that there are numerous controversies that surround it. Will it really work as how it was marketed? Are the promised functions truly what you are going to have once you get it? This is what occurs in the case of LED grow light. You'll find concerns regarding on how the bulbs will perform while growing plants indoors. However, several researches have shown that this controversy does not really exist.As with any other products, a LED grow light features its own advantages and downsides. As compared to other grow lights like high pressure sodium (HPS) lights and metal halide (MH) lights, it runs extremely cool and produces very small of excess heat that could deter growth of hydroponic plants. To enable seeds to germinate, bottom heat is required. Warm conditions are also necessary for optimal plant growth. HPS lights put off more heat and this will lead to warmer growing conditions. This is one of the downsides of LED grow lamps because you'll need a heat supply as a way to have an equal growth outcome.Another controversy with LED grow light is the extra blue spectrum necessary for stocky stem growth in hydroponic plants. In a study done by the Astroculture Flight Unit of NASA, it has performed some testing and they have determined that LED lamps with 80% red spectrum and 20% blue spectrum produced a lot better than HPS lights and other grow lights. Nonetheless, neither of these types of lights produced far better growth compared to sunlight. One option to increase the bloom cycle is to have extra blue spectrum LED lights to imitate the summer light and also the resulting response to plant production. Some of the newest types of LED lights will allow you adjust the quantity of each spectrum for optimal plant growth.There are more of these benefits when you have a LED grow light. As opposed to HPS and MH lights, it requires much less equipment to function. It doesn't requir any ballast, fan or reflector for optimum level of operation. It's going to also last longer with around five to eight times longer than HPS lights when applied to your hydroponics garden.Even though LED grow light is now the more preferred grow light due to its efficiency and durability, HPS lights are also a good option to provide light to hydroponic plants. They may run hot and will not last long, they have lower upfront cost compared to LED grow lights. They also come in blue, red and full color spectrums so you've got your alternative. Many hydroponics garden enthusiasts recommend that a combination of both LED and HPS lights will create the optimal outcomes. HPS lights will supply heat as a byproduct of the lighting to warm the growing environment without having to add a heat source. LED lights will provide the blue spectrum as needed.
