I'm currently running 250w MH along side by side with Tasty's T2-1400 in a DR60 2x2 tent. I can say that fan noise on the Tasty is loud pure and simple, yet then again all axial fans are f*ing loud. It's one of the reasons I abandoned premade grow cabs for tents long ago. This however doesn't take away from the excellent light that is the Tasty! Who knows? Perhaps having a passively cooled fixture just doesn't work with LED??
I researched a lot on LEDs before making my purchase. At the time, and is still probably the case, the Tasty leds are the best value and use the best/newest led technology. I was also looking at the Pacific Light Concepts CXA3070 unit but it wouldn't have allowed me to run side by side with HID in a small 2x2, not to mention the fact it was double the price of the Tasty unit.
The Tastys look far better in person than in pictures. The quality of Rahz's builds are second to none.
