New structure lighting discovery (Atleast for me).

There are many different shapes of these super bright LEDs on eBay.  I like the rectangular ones.

Those are designed to have a heatsink, so be careful driving them too hard, they'll overheat without it.  An auction # would be useful so we actually know what you have.

They have built in heatsinks, left them on about 3 hours and still cool to the touch.  The rectangular ones are not as bright.

John, do COB LED's require a heat sink or are they built into the circuit board?

I don't know what COB means but these have their own heatsinks.

Thanks, Arthur.  Very interesting and informative. 

Now all I need is the translation of LMGTFY

How about LSMALBOWCO ?? You got me on that one.

This is like trying to figure out some of those fancy license plates we have around here. 

Also, I think I am going to order some of the LEDs posted here to try out, I have never used any of these and they do look pretty cool.

Close. 

What's a letter or two among friends.

Made me laugh, thanks 

Don't laugh too hard, you know what happens then!

Now that it's been decoded I remember you telling me that before I think. I would have been here a while if no one had provided any decoding. The poor old memory just ain't what it used to be!!

We are supposed to be having fun and laughing is good for all of us!! (even if there is a little seepage once in a while)

Sorry John I didn't read carefully. These were not purchased VIA an auction site.

So... does it need a heat sink or not?

No it does not. I retested again last night with mounting tape and it was good to go after several hours.
