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
