Found this guy on Amazon:

http://www.amazon.com/Panasonic-LED...l-instruments&ie=UTF8&qid=1395130170&sr=1-101

What on Earth, could they be using in this to justify the cost?

Over the last year, I've bought a few hundred LEDs, all different wattages; making cool white, worklighhts.

Reckon they use gold plated/solid gold, resistors?

I have seen even higher prices.

 

There are always offers to accept a lot more money than something is worth.
Several of us, here on this site, could design and build that from scratch for less than $750, including the price of labor!

 

welcome to the world..
