Many countries, including the United States, are either considering phasing out incandescent light bulbs or have already passed laws to ban them. As standard light bulbs go the way of the dinosaurs, consumers are left with just two viable alternatives, LED light bulbs and compact fluorescent light bulbs (CFLs).

As LEDs are extremely energy efficient and can tolerate temperature variances and turbulence – all while lasting a long time – the quest began in an effort to create light bulbs by clustering numerous LED’s together. And it’s worked. LED light bulbs are now being produced that boast exceptional energy efficiency. A 7-watt LED light bulb, for example, can now replace a 75-watt incandescent bulb. As you can guess, the potential savings in energy costs and greenhouse gasses is huge.

With claims that they can last up to 15 years and use 90% less energy than the traditional bulb, LED light bulbs seem to be a no-brainer at first glance. But problems are prominent and LED light bulbs currently come up short.

LED light bulbs are quite costly. In fact, most people balk at spending $35.00 to $125.00 for just one light bulb, even when it results in a notable reduction in energy bills. Considering most homes have 30-plus light bulbs and businesses have significantly more, switching to LEDs is simply not an affordable option.

LED bulbs are not bright enough. While standard bulbs and CFLs illuminate light in all directions, the light from LED light bulbs is directed or focused, like a spotlight. While this works well for situations such as reading, work areas, and accent lighting, it results in unsatisfactory illumination for general lighting needs.

Their light output quickly degrades. Unlike incandescent bulbs, which release their heat, LEDs contain their heat, which causes their light quality to degrade. Even though heat syncs are added to redirect the heat to a circuit board, issues with temperature overload are still frequent. Tests have shown a loss of 50% of light output in 6 months.

Due to their brightness, stability and attractive pricing (not much more than incandescent bulbs) CFL’s are currently the better choice for most homes and businesses. However, if you decide to take LEDs for a test drive, here are some tips:

Start out by trying just one LED light bulb. You have to take time research and read consumer feedback and reviews. Weigh the pros and the cons. Pay careful attention to warranties and guarantees from both the manufacturer and the store you buy from. Buy quality. Beware of the less expensive LED light bulbs as they are often problematic.

As LED technology improves and the prices starts to reduce,LED light bulbs will be worth taking a second look at in the future. However for now, CFLs are clearly the better overall choice.

LED bulbs

LED is short for light emitting diode. They are like the standard bulbs you can buy around. The distinction is that the LED light gets rid of the use of filaments. These filaments can burn when the bulb is used often. And because this type of lighting technique does not use that, it offers longer lighting proficiency.


How does it function? It simply works by the electron function. Electrons are pushed by using a semiconductor that is specific to LEDs. When this is lighted, it creates brighter lights in comparison to other types of lighting products. It is directly hooked up to a circuit.


It is usually made up of whisker that is then attached to anode. Another part you will discover here is the Anvil which is directly connected to the cathode. What is remarkable about this is the versatility of the light. It comes in various colors such as bright white, yellow, red and green. The white colored ones are not really pure white in color but are bluish white. It is because, it is challenging to create clean white lighting color.


Features of Using LED lights


1. One of its appeals is its labeled efficiency. You can use this kind of light even with minor source of electric energy. It still shines significantly brighter even with less source of current. Therefore, it does not wear out instantly.


2. It does not work with filaments. The original lights use filaments that might burn when used over time. That is why you need to upgrade incandescent bulbs quite often as the filaments tend to burn. Also, this does not exude heat very quickly which can then minimize your electricity consumption. Scientific studies say that most electricity consumed by light bulbs is not because of the lighting but because of the heat generated.


3. Covers a wider area. When you are in setting where you will need more brilliant lights to cover more space, this is good choice. You can use it to attract recognition when stranded in distant place.


4. Another edge is the construction. It is not made of any loosely fitting parts or excess parts that may jiggle around and come loose. It stays unaffected even when you drop it, that is why it is an all-around type of flashlight. It is also produced from a material called epoxy resin rendering it very much durable. However, because of these features, this type of flashlight is more expensive.

LED bulbs

LED lights appeared to be coined as the best kind of lighting system. However, acquiring this from the retailer can cost an arm and a leg because these bulbs are generally more high end than the conventional lamps. But with a few modifications, you can rearrange your worn out lamp to a LED one. You just need to get a LED bulb, do the following actions and you are done:


Step 1: First, you must plan the circuit that you are going to carry out. If you have no idea how it should operate, search for some diagrams using the web and closely follow it. You will find a lot of planned diagrams when you Google for it. Search for the materials you are going to need. Most of what you need can be found in a flashlight so if you have an old flashlight at home, you might like to use the parts including the switch and battery holder. Also purchase the other essentials such as the batteries, the LED bulb and the electrical wires.


Step 2: Now organize the circuit to the strategy you have downloaded. Use the cables to connect the bulbs. If you use a parallel circuit, this could be easier to use. Try the connection primarily by attaching the batteries. If it lights up, it is now running well. After you have already ensured that it is operating, solder the circuits and then let it cool down before mounting it on the light fixture case. You should also leave the battery holder for you to have easier access so you can adjust it should you want.


Step 3: Now check the makeshift lamp you designed. Try for an hour and find out if it does work well. If you wish to obtain a brightness controller placed in your lamp, you could just place a potentiometer in the circuit. Plan the circuit design first before doing this.


Now you could have a LED lamp you can use any moment. This is a great battery saver as it only consumes less energy. This implies you won’t have to change the battery as often as you did with other forms of lamps. Also, LEDs do not have filaments so they do not burn off and thus prolonging the life of the lamp. Instead of shopping one, why not try the steps mentioned previously and make your very own light? You could have a more efficient lights in your area without paying much.
