It has been a few years since the LEDs took the technology industry by storm. Whether in the lighting industry, as a super-efficient option, or in the visual reproduction on screens (e.g. televisions, monitors, smartphone screens, etc.), due to their absolutely breath-taking colour and brightness reproduction, the LEDs certainly have made a profound impact on technology as a whole. LEDs, which stand for Light Emitting Diodes, are basically semiconductor diodes that glow when electricity passes through them. The complex definition of how they work is certainly not something the average homeowner would want to know – but they most definitely should learn of the advantages these new lighting options provide:
- Efficiency – if it was not already stated above, LED lights are efficient. There is a good reason why everything, from LED oyster lights Australia to LED headlights, can be found nowadays, and this is its efficiency. When compared to incandescent bulbs, they are capable of producing the same level of brightness whilst only spending around a fifth of the electrical energy required. When you add this to their lifespan, which is often set at around twenty to fifty thousand hours (or more commonly, mentioned as around twenty to twenty-five years), it should be obvious that efficiency is driving their popularity.
- Brightness – modern wall lights are comparatively brighter to what was available back in the past, and this largely due to the invention of CFLs and LEDs. The early classifications for brightness levels of light bulbs used watts, but nowadays, since LEDs spend a fraction of what the incandescent bulbs do, lumens have taken over as a more appropriate depiction of brightness levels. To provide an example, the average incandescent light bulb can produce around eight hundred lumens at a 60-watt level. LEDs can produce the same level of brightness with a mere 13 to 15 watts.
- Environment-friendly – a big reason behind the drop in popularity of CFL bulbs was the special recycling rules that affected them in many countries. The technology of CFL bulbs called for the presence of mercury (albeit in small levels), which made them difficult to recycle or dispose along other waste at regular waste centres. Not to add, since the glass of these bulbs could easily shatter, they also pose a minor health risk as mercury vapour is released in such instances. LEDs are free from the presence of such gases and do not pose any health risk (and additionally, are also more sturdy).
- Size – LEDs, as stated in the beginning, are diodes. Size-wise they are extremely small when compared to the alternatives, and this gives manufactures way more freedom in terms of designs. This has allowed for a number of different lighting options – which can often be seen in the artistically creative and aesthetically pleasing designs of many commercial buildings.
