My DIY LED "Expansion" Board

<< < (8/8)

Gilligan:
Ok, cool... that is of course the correct way.

Interesting.  I wonder if they are rated at "burst" power?

TCT:
Has anyone tried buying the LED's from reputable places here in the states? Then you don't have to worry about getting the right nm. I was given these names as reputable trustworthy outlets - Arrow, Avnet, and Degikey.


I talked to my dad about this who is retired now, he was head of purchasing for a company that imported millions of LED's dating back maybe 25 years. They eventually ended up having 3 or 4 factories of their own in China and he was the main go between from US to China and vise versa. Anyway, when I asked him about a connection or lead in China he said for the most part it is a crap shoot unless you are going to be moving $100K+. What they say and advertise for nm is not necessarily what is going to ship, for a number of reasons. The places in the states may be more expensive but they have the buying power and discerning customer base that requires accuracy. Just a thought, eliminate one variable from the equation...   

Side note, it was pretty cool my first exposure unit(which we still have) is from Workhorse and when I bought it we found components in it from the company my dad worked for, pretty cool. I also think I've seen their components on damn near all the new M&R autos. Funny how it can be a small world sometimes.

I would never have thought to look, but Digikey has them in a wide range of wavelengths and packaging, etc.
Some draw up to an amp each.
