UFOs in the sky??

Has anyone had experience with the new led technologies? Like the UFO 90 watt and the supernova lights?? Are they pretty good for veg. And flower? anyone have a increase in yield on these lights?

From what I know, most suck! A few of them have quad or 5-band spectrums which are supposedly a LOT better than the original like blue, red, and white UFO's. Because two wave lengths of blue and two wave lengths of red is much more effective than one of each.

I was not impressed seeing a buddies grow. When compared a similar wattage HID, there's no comparison. It's a nice idea using less power but in my eyes you're definitely losing out on your yield when going that route.
