In simple.terms a 240 watt LED light will produce just about as much of a yield as a 600 watt hps with a lower electric bill and its easier to keep temps level with no heat being given off. Also great for stealth grows if your in a state that isnt legal
Now that's a large exaggeration... A BS 240 has an actual wattage draw of around 130w, not capable of producing more than a 600w hps (as tech. stands...).
I'm also glad to see your grow looking better.
P.S. I also believe your UFO's draw 70-90w a piece.
Current*Voltage=Wattage i.e:
Say I'm driving 40x 3w diodes at 700mA. Each diode has a forward voltage of 3.1...
.7*3.1=~2.1w per diode.
40 diodesx2.1w=84w total.
This is just an example, I'm sure you can plug in your own variables and find out the actual wattage of your own LEDs.
Have a good one.
