I'f ur not going to spend more then 500bucks on an led systems its not worth it IMO. I've seen the difference first hand in light output and the panels that work on the HID scale are around $1000. Keep in mind the 2watt bulbs they use for these panels cost about 20bucks each. My hyrdo guy over at the store is putting together a panel to sell that incorporates 3watt leds, its going to be a 600watt HID equivalent and is going to be about 1300 bucks. They sell some really good systems over there but he's trying to get more bang out the same size panel. They have some grows set up in the shop, and the UFO light was ok but not much for flowering and the bigger systems were so intense u couldnt even look at the light with out doing damage to ur eyes. I'm gonna wait for the price to come down on the systems worth buying before i make the decision to change.
