Earlier, you used to find LED Light bulbs only in specialty stores and in general, their use was very restricted. However, with time, the advantages of these bulbs started being realized by people for using them at offices and homes. Apart from these, the bulbs can be used for street lighting, retail stores and exhibition halls too. Earlier, people used to not consider LED lights for all purposes, due to their expensive prices. However, now, there has been a gradual reduction in the prices and there are several advantages that help in overlooking the cost factor. Given below are some advantages through which the popularity of LED lights and LED Light bulbs have increased over a period of time.
1) Reduced power consumption
When we talk about LED Light Bulbs, they consume very less power as compared to the compact fluorescent lights or incandescent bulbs. The cost of these bulbs might be higher but owing to their low consumption of power, it definitely becomes a very cost-effective option. There would be a considerable reduction in electricity bill when these LED bulbs are used.
2) High Energy Efficient
Even if the consumption of power is low, these LED light bulbs are considered to be very energy efficient as compared to the traditional bulbs. This is because, these bulbs have the capability of emitting more light per watt. Owing to this, they contribute further to the cost saving advantage.
3) More life
Owing to higher energy efficiency and lower consumption of power, the life of LED light bulbs is considered to be more as compared to the traditional lights and bulbs. It is definitely a very good fact that the life span of these LED bulbs is more than 30,000 hours and that of traditional ones is just 1,000 hours. One can operate these bulbs for around 20 years without the need of being replaced. This is definitely a very good advantage that makes people opt for it. A popular option among these is Gx53 LED which is a very cost effective option.
4) Environment Friendly and Safe
Another advantage that LED lights offer is that they aren't very safe for humans only, but even for environment. Firstly, there are no filaments in it, as seen in traditional bulbs. Thus, the LED bulbs would never burn out. Another important aspect to be noted is that disposing compact fluorescent lights is very difficult owing to the content of mercury in them. There is no toxic material or mercury present in the LED Light bulbs. Thus, it is not at all difficult to dispose off these LED bulbs and the environment is not damaged in any way. Additionally, there is no risk of UV light emission. This has increased their popularity for use at offices and homes.
5) Available in a good variety
LED light bulbs are available in various colors, sizes and shapes and offer exciting arrangements. You can find them in entertainment venues, shopping malls or in night clubs. Moreover, they are acclaimed highly by corporate houses for business promotions or advertising. Even though they are available in a large variety, you can install them in regular fittings.

How to Make a Lemon Battery
Lemon (fresh and juicy)
Nail (2"galvanized, zinc-coated steel nail)
Lemon Battery Light Bulb Experiment
The first step is to cut a slit into one side of the juicy lemon, and insert the clean copper coin into it. On the other side, insert the galvanized zinc nail. Ensure that the nail and coin do not touch each other. The coin and nail form the positive and negative electrodes respectively, thereby forming the single cell of the battery. The two oppositely charged electrodes will now permit the flow of electrons through them. The free electrons from the lemon juice will travel from the negative electrode (nail) to the positive electrode (coin).
The rate at which the electrons flow is called voltage. The faster the electrons flow, the higher the voltage. The voltmeter will measure the rate of electron flow. If one connects the voltmeter to the electrodes, a voltage of 0.906 volts will be detected. However, this is not enough to light a bulb.
To achieve enough voltage to light the bulb, one has to make more lemon batteries and connect them via a metal wire. The metal wire should connect the positive electrodes to the negative ones, and this will add voltage from each cell. Take four lemon batteries and join them together from positive to negative. A total voltage of 3.50 volts will be created, which is enough to light up a small light emitting diode or LED light.
At the plastic base of an LED, one will find two wires and a 'flat spot'. The wire just besides the flat spot needs to be connected to the negative side of the battery, while the other wire needs to be connected to the positive terminal. The electrons flow from the nail end to the coin end, thereby forming an electronic circuit which causes the LED to glow dimly.
The above steps on how to make a lemon battery can help one make a lemon battery at home without much effort. LEDs work at even very low voltages (below 2V) and low currents. These LEDs get damaged if connected to batteries over 2 volts. Thus, they require resistors to control batteries which are rated over 2V. However, since lemon batteries produce low current, it is safe to connect an LED to it. However, in this lemon battery experiment, the copper coin can pose a problem. The coin should be pure copper. One can substitute a 14 gauge copper wire for the coin. One can try out different permutations and combinations of electrodes in the lemon battery experiment.
Installing under cabinet lighting in your kitchen has many benefits. Under cabinet lighting uses low-voltage bulbs to make tasks easier and safer by delivering directed light to a specific area. Under cabinet lighting can provide two functions in your kitchen. It can provide task lighting for countertop food preparation and accent lighting to highlight your countertops and backsplash. Although under cabinet is also useful in workshops, garages, and basements, here we will focus on the kitchen.
Benefits of Under Cabinet Kitchen Lighting
1) Energy efficient - Under cabinet lighting can save energy by eliminating the need to light up an entire room.
2) Variety of bulbs - Energy efficient lights bulbs are most often used for under-the-cabinet lighting fixtures. Common under cabinet light bulbs include fluorescent, halogen, LED, and xenon bulbs.
3) Eliminate shadows - Under cabinet lighting reduces the shadows created by wall cabinets and overhead ceiling lighting. Proper spacing of under cabinet lighting eliminates the dark shadows under your countertops. To eliminate shadows, install one light for every 20-30 inches of counter space.
4) Add unique style and distinction to your kitchen - Many kitchen countertops are made from granite or marble. A kitchen under cabinet light can make your stone countertops shine.
5) Simple installation - Many DIYers can install under cabinet lighting in just a few hours.
Types of Under Cabinet Lighting: Strip Lights, Puck Lights, Linear Lights
Strip Lights: These are rectangular shaped fixtures and they work well with fluorescent bulbs. They are great for providing diffused light to the kitchen.
Puck Lights: These are round fixtures that got their name from their round, hockey puck- like size and appearance. These lights are best for highlighting countertops and backsplashes. Puck lights work with LED, halogen and xenon bulbs. Puck lights can be mounted in different positions to either aim downward or at the backsplash. As an alternative, puck lights can usually be recessed into cabinets.
Linear lights: Linear lights are often used with fluorescent bulbs. They are the most popular types of fluorescent under cabinet kitchen lighting because they are thin, which allow them to be concealed behind the cabinet trim.
Types of Bulbs Used for Under Cabinet Lighting: Fluorescent, Halogen, Incandescent, LED and Xenon.
Fluorescent bulbs - These are commonly used for under cabinet lighting fixtures. They create a bright work area by providing clear light. The disadvantage of fluorescent lights is that they cannot be dimmed and they sometimes flicker.
Halogen bulbs - Homeowners seeking a bright, white light choose halogen bulbs. The light emitted from a halogen bulb is warm and bright and provides a nice amount of light from under the cabinet. These bulbs have an extremely long life, lasting up to 2,000 hours.
Incandescent bulbs - These bulbs are the least popular under cabinet bulb type as their light is not very bright. Incandescent bulbs are not energy efficient and they emit heat. They last half as long as halogen bulbs.
LED bulbs - These bulbs are becoming a more popular choice among homeowners as they become more commonly available at lighting and home improvement stores. LED bulbs are available in different colors they and provide homeowners with the ability to create unique decorative features. LED bulbs are best for puck lighting.
Xenon bulbs - These bulbs have the longest lifespan of all under cabinet light bulb options. They can last up to 10,000 hours. They are energy efficient as they do not create heat.
Tips for Successful Under Cabinet Lighting
* One 12-inch lighting fixture or 3-puck light fixture should be installed for every 4 ft. of countertop.
* Install the lights toward the front of the cabinet so that they will highlight the surface best.
A light tower is one of the most useful illumination devices for lighting up large areas. It essentially comprises a tall post that has been fixed with a light assembly at its upper end. These towers are installed on small, yet heavy-duty trailers that enable the user to transport the light tower from one place to another.
Light towers need to be powered by fuels such as diesel or gasoline. Portable light towers can be easily transported from one place to another. They can be set-up at construction sites, mining sites, search and rescue operations, outdoor events, parking lots, or at any place where electrical power isn't available. These towers are also used during natural calamities such as cyclones that tend to snap power supply.
Depending on the amount of illumination required, one can opt for a 4-light, 8-light, 12-light or even 16-light tower. You could choose to switch on a limited number of lights from the light assembly. For instance, you could switch on just 2 lights in your 4-light tower if you need limited illumination.
If you are considering an investment in light towers, the portable light towers are a recommended option. Here are some main characteristics of a light tower:
- Construction: The materials used for constructing these light towers are of prime importance. Manufacturers make use of galvanized steel masts and frames to ensure that corrosion doesn't affect the structural integrity of the light tower.
- Sturdiness: A light tower will likely be used in places such as construction sites, mining sites, oil fields, etc. All of these sites are exposed to dust, vibrations, harsh weather, etc. A light tower that is sturdy can offer undisrupted light despite the worst of conditions.
- Functionality: Features such as 360 degree rotation, ability to stand stable in high-speed winds, easy transportability are some other desirable attributes of light towers.
- Power: Depending on the amount of illumination required, light towers are available in several different power options such as 6KW, 8KW, 15KW or 20KW.
While there is little doubt that a light tower is a reliable source of lighting, they are expensive. If a business doesn't wish to divert thousands of dollars in purchasing a light tower, they could choose a rental scheme. Yes, portable light towers can be rented to fulfill various industrial requirements. This enables a business to save money without hampering their critical operations.
While a touch table lamp can be complex on the inside, the outside can be simple and beautiful. These lamps have features that allow you to control different levels of brightness depending the mood you like to set. They are also easy to use because they require only a touch of your finger to operate. If you are trying to find a lamp that is within your budget, you need to shop around to find the best deal and still find one that fits your style.
Prices on these touch lamps can really vary due to different factors. The brand, material, model and style can all affect the price. Certain brands that are well known may be higher in price. Don't feel that you can't buy a lamp from a brand you are not familiar with. They can often be lower in price but still reliable. Just check reviews before buying. The material can greatly affect the price as well. Depending on the style you want, lampshades can be constructed of satin, twill or plastic. Different models will have different wattages. The stronger the wattage is, the more costly the lamp may be. You can purchase LED light bulbs that will increase the brightness of your lamp.
Do some research online before you purchase your new touch lamp. You can compare different websites side by side and find the best price for you. Often website companies offer deals such as free shipping. Scour the local garage sales and swamp meets on weekends. You can find lamps in great condition for a fraction of the price. If you have great bargaining skills, use them. You might be able to bring the price down even more. Watch for sales in your local department stores and newspaper ads. Stores need to turn their inventory often and then will lower prices on lamps to try and sell them.
You also need to consider the style and theme of your room before purchasing a new lamp. Consider where you will place your lamp and think about what colors will work well with it. Ask yourself what theme your room is. Is it rustic or modern? Country or sleek? This can help you narrow down your search. You also need to consider if you want your lamp to be simple and blend into your current home dÃ©cor or if you want it to stand out. Simple lamps will generally have a low price point. The more decorative a lamp is, the higher the price may go.
When deciding on how much you want to budget for your new lamps, consider the usage. Will you be using it daily? How often will you turn it on and off? If it will be used quite often, look for a lamp that is higher quality. It may be a bit more expensive, but it will last longer. This will save you money over time as you will not have to replace it when it breaks. If it is to placed in a room where it will be rarely used, you can cut costs by buying a lower quality one with a cheaper price tag.
25% of a typical home's electricity is spent on lighting inefficient incandescent light bulbs. Each year, more and more homeowners are choosing to replace their incandescent bulbs with more efficient bulbs. Two of the most efficient energy saving light bulbs used in homes are CFL (compact fluorescent) and LED (light emitting diode) bulbs. Both of these bulb types have become more popular as home owners realize the great energy saving benefits. While CFL and LED cost more than the conventional incandescent bulbs, they prove to last much longer. You won't need to replace CFL and LED bulbs as often as incandescent bulbs.
CFL bulbs are compact fluorescent bulbs that have a twisting shape appearance. They are more energy efficient than incandescent bulbs because they produce less heat and last longer. They use 1/3 the electricity and last up to 10 times as long as incandescent bulbs. For example, one, 18 watt CFL in place of one, 75 watt incandescent bulb, will save about 570 Kilowatts (kWh). The average cost of electricity per kWh is 8 cents per kWh. This would yield about a $45 savings for just one bulb (Eartheasy.com). Other advantages of using CFL bulbs include that they help reduce air and water pollution by producing less carbon dioxide (CO2). Replacing one incandescent bulb with a CFL can prevent as much as 450 lb. of carbon dioxide from entering the atmosphere. CFL's provide a higher quality light compared to the bright white light of incandescent bulbs.
Some homeowners fear using CFL bulbs because they contain small amounts of mercury. Electrical safety experts believe that the mercury in a CFL is not dangerous. The only danger associated with a CFL bulb is if it breaks and is not cleaned up and disposed of promptly and properly. Proper clean up consists of sweeping up the glass from the bulb (do not vacuum) and disposing it in regular trash.
LED (light emitting diode) bulbs are used in lamps, small lighting fixtures and for Christmas lights. They are also used in small electronics, such as DVD players, as well as in tiny flashlights. Nowadays, LED bulbs are being used for more residential lighting applications, such as under-cabinet lighting, in recessed lighting fixtures and for landscape lighting applications. LED bulbs have an extremely long lifetime. They can last between 50,000 to 60,000 hours. This is more than four times longer than CFL bulbs. LED bulbs use only 2-10 watts of electricity (1/3 to 1/30 of incandescent or CFL bulbs). As with CFL bulbs, LED's don't produce heat. According to Eartheasy.com, "LEDs produce 3.4 BTU's/hour, compared to 85 for incandescent bulbs." In 2009, the first LED-based replacements for a traditional light bulb were made available to the public. These bulbs give off an amount of light equivalent to a 40-watt incandescent bulb. Most homeowners use 65 watt bulbs and higher. However, the extremely long lifespan of LED bulbs has made them into a popular choice.
