Short comparison of Light Bulbs

So today we are going to discuss different type of light sources and their pros and cons

As we all know incandescent bulb has been around for more than a century lighting homes. A lot of people know the name Thomas Alva Edison, the man who invented the light bulb. Some among us might not know or remember this fact. The year that saw first electrical light being born was 1879

Change and improvement never stops and this applies to everything in life. This invention was not immune to this phenomenon. Soon Fluorescent bulb was invented at the turn of the century that proved to be far more efficient in converting electrical energy into light. However this type of light source required some additional gears called choke and starter to produce light. This apart from tubular shape restricted its applications

HID or High Intensity Discharge lamp were the next generation of light source that brought big change. The bulbs produced one of the highest amounts of luminous flux per watt of electrical power consumed. This made it light source of choice for lighting up large areas such as sports fields, large factories, street and large warehouses.

Compact Fluorescent Lamp also known locally as Energy Saving lamp came out in 1990 even though it was invented in early 70’s. This truly revolutionized lighting scene that lasted unchallenged for 3 decades until LED technology became commercially viable to produce electric lamps.

Now LED stands as one of the most efficient source of light. In last 10 years it has become so widely used that its almost impossible to find a home or a commercial establishment that does not have them.

To put things in perspective a 100W incandescent bulb produces about 1500 Lumens while a CFL or Energy saving globe uses 25W to produce the same amount of light. When it comes to LED it only takes about 16W to produce the same amount of light while lasting 10 longer than an ordinary bulb. During the recent times we had seen such a rapid decline in price of LED bulbs that they tend to be much cheaper than any other type of bulbs in during initial purchase. If one really try and look at cost benefits over the entire life cycle then it makes such a compelling argument to buy nothing other than LED light bulbs
