Wondering where i can buy large(long) heat sinks for COB chips? anyone got a site? Also where are you guys getting your chips, fans and drivers etc? Ebay, china, etc? Id love to build a 8 foot long heatsink with passive cooling (no fans).

Can we get more specs on the led lamps? are they cob(square) style? (they must be, cause anything else is a waste of time IMO). Can you take some up close pics of the lamps? how many leds and how much (advertised)wattage per chip ? I assume your AC is working alot less now too eh?

Are those COB style leds? Do they actually pull 390 from the wall? I assume they put off way less heat than the 12 hps? Nice setup. Nice big buds, you know what you are doing. What strain is it?
