A Rutland village has cut its energy bills by almost 80% by switching to more efficient lighting.

Market Overton's street lighting bill fell from about £80 in October 2010 to about £15 in November.

The savings are as a result of replacing the village's old sodium street lights with modern light emitting diode (LED) lamps.

The parish council also turns off some of the village lights between midnight and 0500 GMT to further reduce bills.

Parish councillor Andrew Stewart said: "We still have the lights on at important junctions and places you would need to see.

"Turning 80% of them off at midnight has really helped to save money and to cut our carbon footprint."

The parish council updated its 39 street lamps at a cost of £20,215 with about a quarter of the cost being met by a Rural Community Council grant.

Councillors said the village would no longer receive a quarterly £600 bill for maintenance and the lamps were guaranteed for 12 years and expected to last for 20 years.

In order to get a upper-hand position in the global LED lighting market, Taiwan-based LED chipmaker Epistar will actively lower the brightness cost of LED lighting products and aims to reach the goal of US$1 per 500 lumen in 2012, three years earlier than the schedule set by the US Department of Energy (DOE).

Chairman of Epistar, Lee Biing-jye, indicated that Epistar aims to reach clients' expectation ahead of schedule and take a lead in reducing the cost per lumen in order to become the leading LED supplier in the global LED lighting market in 2013.

Market sources also noted that due to benefits from increasing demand from TV backlighting and the general lighting market, Epistar's revenues in 2011 are expected to reach NT$27 billion (US$931.04 million), an increase of 37% on year.

Based on Epistar's internal schedule, overall LED lighting costs will drop to US$1 per 250 lumen in 2011 and the company should have a 5% share in the global lighting market. Epistar aims to reduce the cost of LED to US$1 per 500 lumen in 2012 and boost its overall market share of LEDs to 10% of the global lighting market, and to US$1 per 1,000 lumen in 2015 with a 25% market share, and to 60% by 2017.

Epistar indicated that current market price of a incandescent bulbs is about US$1.5 and US$2.5 for an energy-saving lighting bulb, while quotes for an LED light bulb from a factory is about US$5 and US$12.5-15 in retail. If the market price of an LED light bulb drops to US$7-8 in 2015, the market share of LEDs in the global lighting market should be able to reach 25%, and help to drive the overall LED lighting industry value to account for 50% of the total lighting market.

LED Bulbs - The Light Of The Future

As we become more conscious about the effect that the use of electricity is having on our planet. So the more aware we are becoming of looking for ways to reduce our use. As a result of this the sale of LED bulbs has increased substantially in the last few years.

Today it isn't just companies who are choosing to install such lighting but many homeowners as well.

So what are the reasons for so many us choosing to spend money on installing LED light bulbs rather than sticking with the incandescent and fluorescent ones?

In this article we look more closely at the features of LED bulbs and which will explain to you why such lights are proving so popular today.

Feature 1 - Luminous Flux

At the present time LED lights have the ability to produce a luminous flux of between 1 and 120 lumens. In turn they need only to use power of between 50-100mW (MiliWatts) and 5W (Watts) to create the light they produce.

Feature 2 - Color and Color Temperature

Most of the LED bulbs you see today emit a very neutral white light which many of us see as being cold. However research is being carried out and in the future the lights will be able to produce a much warmer light that looks very similar to that which a traditional tungsten or halogen bulb produces.

Feature 3 - Life Span

As these lights use less energy to create the light they don't get as hot as conventional light bulbs do and this in turn means that they last considerably longer. If you are willing to purchase good quality LED bulbs you will find that they will provide light for between 30 and 50,000 hours. Whereas you will often expect a conventional light bulb needing to be replaced between 5 and 10,000 hours.

Feature 4 - Light Distribution

How intense the light distributed by such bulbs is will depend on the housing used and what sort of carrier or reflector has been used to place the semiconductor on. Certainly the better quality these components then the more intense the light distributed will be. On average the amount of light emitted can vary dramatically and the angle at which it is emitted varies also. In some bulbs the angle is just 15 degrees whilst in others it can be as much as 160 degrees.

Feature 5 - Energy Efficiency

These are considered to be among the most efficient form of lighting you can get today. At present most of these bulbs are able to emit around 30 lm/w of white light. However there are a few now that have the capability of emitting 50 lm/w and hopefully at some point in the future some will be able to emit 100 lm/w. So it won't be very long before these types of bulbs have the ability to emit the quality of light that traditional light sources currently provide.

As a result of all these features it will not be very long before you seen LED bulbs replacing the much more inefficient forms of lighting we use currently.
