1) What does LED mean? | |
LED stands for Light Emitting Diode. The first two words are easily understandable! The third on refers to a electronic component which is widely used in electronic circuits. It is actually the most common electronic component that can be found in almost any circuit that you can think of. Its' function is to conduct when biased the right way and behave as an open switch when biased inversely. The first diodes where used in rectifying alternating current, that is convert AC to DC, in conjunction with other components likes capacitors, coils etc.

3) What are the applications where LEDs can be used to maximize savings? | |
They can be used in any place you can think of. Home use, businesses, shops, restaurants, hotels, warehouses and virtually any interior or exterior space are only a few to consider. Replacements exist for almost any conventional light type that lies in houses or any business or even exterior spaces like parking lots, tenis fields, gardens etc. Incandescent Bulbs, Halogen spots like MR16 or GU10, Fluorescent tubes, PAR Halogen spots, ceiling lights like PL with G24 fluorescent lights, hidden lighting, industrial lighting for factories and warehouses, Flood lights (IP65 or better).

4) What are the savings that can be obtained depending on the application? | |
Savings, as far as LEDs' use is concerned, start at 50-55% and reach up to 90%.

5) How can i compare a conventional lighting fixture with a LED one? | |
Ways to get a first idea about the savings are the characteristics of the lighting fixture written on its' box. Values like Lumens (lm) or Watts are common on any light's box. These two values can give you a very good idea of the lighting performance of that specific light type. If you divide the Lumens value by the Watts nominal value indicated on the box, then you have a very clear view of the efficiency that the light can reach. Lm/w is the best way to compare lights. The second characteristic that you should be looking for is the effective lifespan. That is given in Thousands Hours. For example, an old incandescent light bulb can reach, at its' best, 1000 Hrs. An equivalent LED bulb can reach the boundaries of 50000 Hrs, which is quite common for LEDs as long as the quality of construction is well above average. That means that properly calculated circuitry, LED chips current drive and most important thermal dissipation on the LED chips will usually lengthen their life span and reach 50000 Hrs as long as all these range well within the LED chips' manufacturer limits.

6) Are any alterations in wiring necessary to replace existing conventional fixtures with LEDs? | |
You usually do not need to apply any alterations in wiring. That means that you will only pay for the LEDs cost. 90% of the cases, you don't need to do anything. You just take the old one out and install the LED one at a blink of an eye!

7) I have been told that LEDs are expensive. Does it worth buying? | |
People's attention is usually misleaded by wrong information which eventually makes them focus on the initial purchase price rather than the savings that they will get during the next years or even the estimated lifespan. Big shops or other extended spaces like warehouses that keep lighting on for more than 8 Hrs a day will literally save hundreds of Euros every month! It is simple math.
