Hi Folks !
Well, the long awaited LED information is here !
This will be as detailed as I can possibly be, and I will attempt to be as accurate as possible.
If you know electronics, and you find mistakes or blatantly incorrect information PLEASE correct me !
LED’s are the wave of the future for lighting. No doubt about it. They use milliwatts of power and compared to other forms of lighting they hold up well in terms of brightness, depth of colors, power use, and especially lifetime.
On average a LED will burn for 100,000 hours the equivalent of 11 years. Not all LED’s are the same, as in everything else, the quality of manufacturing is key. ALL LED’s grow progressively dimmer as they burn, it is the MFG quality that determines how fast that arc of burn down occurs. Some will lose a lot of brightness in their first few hours, while others will take years to lose noticeable brightness. With that in mind you have to consider your application of the light, and if it is critical that it performs consistently.
All LED’s are DC voltage.
While there are AC house current “bulbs” that are LED, they contain in their base an AC to DC converter. Here again the quality of manufacturing is key, as lifetime can be considerably shorter due to burnout of the converter while the LED’s in the “bulb” may still be functional. (so DON”T throw a AC LED “bulb” away, dismantle it and harvest the parts !!)
The COST of the AC-LED “bulb” is NOT a guarantee of quality ! Some are quite cheap, some are quite expensive, and sometimes the cheap one will outlast and outperform the more expensive one ! The LED market is in it’s infancy, and as such it is the wild west out there. Myriads of manufacturers mostly in Asia, Myriads of stores, and even greater number of websites are popping up everyday.
Just now I did a simple search on google on the term “LED”:
About 425,000,000 results (0.11 seconds)
So, you can spend hours and hours of looking at websites and never reach the last of the 425 MILLION sites !
I will attempt to narrow it down a tad for you, or at least make you a more educated consumer.
