You still using the one original led, or have you changed/added others?
I still use the two panels, the original from Fero EU (bulldog) on 280W with 120x3W LEDs
and the extra LG panel on 192W with 96x3W that I got in order to cover all of my 1x1M grow space
witch give me a total just over 470W and the same result (or better) then with my 600W HPS and with way less heat
