Osrams are better quality led than epistar. I don't like not having fans on the heat sync even if its not enclosed though. The astir panels don't have fans but they are little 24w (18w) panels so its ok.

Ho, the same concern here, can that heat sink spreads all heat? But anyway, Rhino is a good item I think, Osram chips, Made in the USA, we get what we pay for.
 
Ya, i own 4 Rhino 400s. Im using them as supplemental lighting along side of a 1000watt HPS. The results have been Amazing, im having trouble getting my video up, but ill have something up soon. Cheers

Actually they are more than ok, they never get hot. Low wattage- big heatsink
My little friend sitting on the fins tells the truth :)

If you go only passive cooling you have to get a big heatsink and with the right fins to work properly.
Otherwise you need some fans.
