Although it claims a 100-year life, the power LED in this video comes to an early demise.
My chum Rick Curl just caused me to waste a few more minutes of my precious time by pointing me at this video from Big Clive at BigClive.com
In this video, we see Big Clive experimenting with a 100W power LED that he claims boasts a 100 year life. Sad to relate, as we soon see, the LED in this video came to an early demise. As Big Clive so eloquently says: "...all the little chips inside have gone black now and they're not supposed to do that."
All I can say is that this video is excruciatingly painful to watch yet -- much like an impending train wreck -- you canít drag your eyes away. The point where Big Clive starts his "TIG Welding" (at around the 1:00 minute mark) will be forever etched on my memory.
On the bright side, I did discover some useful nuggets of knowledge of which I was previously unaware, such as the fact that "With Power LEDS polarity doesnít matter because they use bi-polar alternating watts" (this is something they inexplicably failed to teach me at university).
Furthermore, the comments to this video are instructive in their own right. As one viewer noted: "Everybody knows that TIG welding should be done in an atmosphere of pure helium which you didn't do otherwise your voice would have been higher." Dang, I should have spotted that myself!
@Alex: ...the video did bring back memories of building a motor as a young boy...
I know what you mean -- it sort of reminded me of some of the things I did as a lad -- but I do get the impression from watching some of Big Clive's other videos that he knows a lot more than he lets on, as it were.
The bright LED intrigued me enough to look them up. The 100W power LEDs are rated for 30-34V and the video looks like he hooked it up directly to 220V main. It is no wonder that it blew up. Also, the specs say that the LED must be mounted on a heat sink since even at the rated voltage they get very hot.
Though the video did bring back memories of building a motor as a young boy and when it didn't work with teh battery I had, I tried connecting it directly to the 120V AC power. The motor burst into flames almost immediately. Very disappointing and very funny at the time.
