'Redline's LED - DiY - Build' aka"GROW LIGHT"

sorry for all the basic questions, but I have another one. I tried finding the answer online but no luck. I want to wire 10 in series. my question is do I just solder to one positive and negative pad or to both of them? I attached some pics with different examples I found online, but wasn't sure which one to use,

Thanks

The positives pads are connected to each other on the star, as are the negative pads, so use whichever pad is easiest, or looks better, it does not matter. But just one of each will work fine.
I'd suggest that you wait and get them soldered before you glue them down, though.
Line things up and cut n strip the wires, then remove the stars from the heatsink and do your soldering, then screw, glue them to the heatsink.
If you glue them down first and then try to solder, you will need a honkin' big iron and some patience.
Don't ask me how I know:(

Havin' fun yet?

:wtf::wtf: That third picture makes no sense.:wtf::wtf:

Weeze

thanks weezard. I didn't think the 3rd picture made any sense that is why I asked you guys.

hi,
i am looking to build a similar set up to mcqueen and b0fin but have no way of contacting them. Have another thread started here -

Designing an LED grow light - GreenPassion.org - Dedicated to Medicinal Cannabis Cultivation and Education.

which seems to be current and am about to invest in some cree or K2s only wondering which are better.

also have seen these pop up recently on ebay and am wondering if they look like a better new technology to use? Here is my original question -

Before I go ahead and stock up on Crees or K2s (any idea which is preferable?)
has anyone seen these going? I am trying to find out who manufactures them but all I've seen so far is what is on ebay. Check out -

1x High-power brightness 10W RED LED 260Lm Save Power7V on eBay (end time 24-Sep-09 14:49:29 BST)

or

1 PC BRIGHTEST 25W WATT HIGH POWER WHITE LED 1400 Lumen on eBay (end time 26-Sep-09 11:38:00 BST)

Could these be the latest technology that I have been hearing rumours of?


any contact on this appreciated. go via the original thread i posted if this one is dead
