LED v/s Halogen
I just received a timely, interesting and informative comment on an earlier post about LEDs v/s Halogen from "Dong" who does not identify him/herself. (I wonder if that by any chance is Ding's brother) - (sorry about that - I just couldn't resist it)
I decided that the comment is worthy of a full posting so here it is:
Well, judging from the way it is, I must confess I was once also mislead into believing that a 3 or 5 or 7 Watt LED MR16 can replace a 50Watt Halogen. There is no way possible!
However, it strikes an interest to me, as I go on deeper into the technical world of LED lighting. First, we must understand that manufacturer’s claims on their LED products are totally not 100% accurate, and some are in fact way too misleading. From my understanding, the higher Wattage does not make the LED any brighter nor efficiency.
In LED, we must refer to the lumens per watt (lm/W), and currently CREE has the commercially highest rated lm in the market, 100lm/Watt. Thus a one Watt CREE LED can be brighter compared to the 5Watt Taiwan made or china made LED, which most probably managed 50-70lm/W. I have therefore bought some 3Watt CREE LED MR16, and true enough, they are bright enough to really replace a 20Watt Halogen, and it will be a matter of time before they can replace a 35Watt halogen.
With regards to replacing a 50Watt Halogen MR16 with LED, as far as I understand, there is only one company that have actually produce a LED in the form of dichloric MR16, and REALLY pumping in lumens that matched the 50Watt Halogen! I personally tested it, and I was really amazed by it. The unique design, with their proprietary optic lens that equals the beam angle of 3 most common angle of the MR16 (20 Degree, 35 Degree and 60 Degree) definitely deserve my thumbs up.
This is by far, the brightest LED product I have ever lay my hands on, that can replace a 50Watt Halogen MR16. The simple features that allows us to do a one to one replacement without changing our existing fixtures, or doing any modification works to our ceiling, terming it simplicity at its best!
Dong did not say who the company are - I wonder???
