No. Its 650W at 500mh :> or 550W@500mh if You have hardware mod
What kind of 'hardware mod' are you talking about?
TIA
Yes please elaborate on the hardware mod for lower wattage as never heard of this option before and willing to play around with a unit and try it out?
Cheers
im guessing he took off the circuit responsible for the software voltage adjustment and added an adjustable resistor that goes to a lower value.
