LEDs lights are very efficient, but because of their structure, much of the light in standard LEDs becomes trapped, reducing the brightness of the light. Because of this, LEDs are only useful for “task lighting” in the home — as floor lamps and desk lamps
Dr Faiz Rahman, the researcher leading the project at the University of Glasgow, said: “By making microscopic holes on the surface of the LEDs it is possible to extract more light, thus increasing the brightness of the lights without increasing the energy consumption. As yet, LEDs have not been introduced as the standard lighting in homes because the process of making the holes is very time consuming and expensive. However, by using world-class facilities at the University of Glasgow we believe we have found a way of imprinting the holes into billions of LEDs at a far greater speed, but at a much lower cost.
“LEDs not only use less power than current energy efficient light-bulbs but they are much smaller and can last years without needing to be replaced. This means the days of the humble light-bulb could soon be over.”

Many people assume that LED lighting is still not ready for general area illumination, yet we provide true high brightness, low wattage, long life, sustainable LED bulbs that require nothing more than removing your existing inefficient 12V MR16 Halogens, 120V GU10 Halogens or your regular Edison screw based Incandescents or CFLs to start saving.
The technology is already here and being used for many general illumination applications. At eLumanation we offer sustainable, energy and cost saving lighting options while being the most environmentally friendly lighting option available.

I noticed that you have a LEDtronics S14L LED bulb pic on your website; but I did not see any credit to LEDtronics for using our picture.
Please add a credit to LEDtronics under the picture that you are using.

Energy saving is a great mantra in coming centuries, to keep human spirit lighting and glittering.
Great that all of us have common goal, irrespective of countries and domain areas.
Thanks for this publication.
