Incandescent

The incandescent bulb is one of the first bulbs created. Having such a widespread effect in lighting, the incandescent bulb has dominated the lighting market since the beginning, only now beginning to phase out. As manufacturers moved into the CFL (compact fluorescent lamp) bulbs, a decline in the number of incandescents was visible. 

This was first visible by the end of frosted bulb manufacture, and the reason? Energy efficiency. Due to the rise in electricity bills and other factors, most home owners try and aim for other means of light, meaning other types of bulb. As us lighting retailers and manufacturers know now, it is less cost effective to produce incandescent and even halogen bulbs now, due to the current market.

Comparison

So how does all of this effect us? 

Well in comparison to other bulbs, the incandescent is essentially useless. Because of the new bulbs and lighting ranges available, the incandescent not only proves to be inefficient, but beginning to be too costly. 

Furthering the disadvantages of this bulb, as I'm sure many of you know, the incandescent produces immense amounts of heat when lit. This makes changing a bulb more of a chore in it's own as well as the factor of blown bulbs. Carrying this through, because of the heat, the lifespan of the bulb was fairly short lived, having the temperature reach soaring heights and causing the bulb to shatter and blow.

CFL (Compact Fluorescent Lamp)

One of the first major advancements that were made in the light bulb world was the development of the CFL bulb. Using certain chemicals, this bulb was able to produce a large amount of light for a low return in wattage. Some bulbs being up to 80% energy saving, the CFL made a large impact on the lighting market, often out of stock. Even though this bulb seemed like a god send in comparison, it was not the most aesthetically pleasing bulb. Most chandeliers would reject the opportunity of this new bulb, as whatever lamp had the bulb on show, not sheathed by shades and fabric, would also reject the offer. 

An even bigger mistake was then made by the free 'energy saving' CFLs were distributed to the UK. These bulbs took far too long to reach the brightness intended and were also not as reliable as originally thought. Most lasting the same as the predecessor incandescent, left a large scar on any CFL manufacturer.

LED

Following the somewhat success of the CFL bulb, along came LED. LED's were normally used in TV's and other display systems, until it was recognised as opportunity for bulbs. 




Advantages

To start off the vast array of advantages, the LED has reached new heights in terms of energy saving. Being A+ rating, the 90% - 95% energy saving bulb is now looking to go into consumer and commercial use. Having large interest from bodies such as councils and large corporations, simply for the quality and low energy that the bulb uses. This could mean major energy savings all around for companies to consumers. With such low wattage and the fact the bulb doesn't get hot working from small emitters, the lifespan is the greatest ever seen in bulb manufacture. Some bulbs lasting up to 35,000 hours, in other terms, these bulbs may now be seen as an asset and solid investment for future generations. 

Disadvantages

Because of the extremely low wattage however, this means that a large portion of LED's are not dimmer compatible, putting a large audience from buying. Not only that but the amount of fakes, claiming to be over 15,000 - 30,000 hours is vast, meaning that trying to find a genuine supplier and retailer is difficult. Not only that but in the initial launch of LED bulbs, the price is high. Regardless of the savings made from switching to LED, the price is another factor that isn't pleasing.

Summary

To conclude this article on bulb advancement, it has been determined that the LED is a hands down winner. Because of the sheer lifespan and energy saving available when switching to LED, makes it an unmatched opponent in the market. 

Even though the benefits are huge, it must be severely noted to only buy from solid and reputable suppliers, as many claim LED standard, when in actual fact not. Make sure to be thinking of switching over in the coming years, you don't want to be left behind.
