Electronic ballast, with "Flip/Flop" technology, for HID lamps of 250W, 400W and 600W.
New Flip Flop technology for unmatched flexibility
The Maxibright DUO has six power settings, manual primary and secondary output, 12-hour and 1-hour automatic Flip Flop settings.
Use this ballast on two grow chambers to power them alternately, choosing either the manual primary/secondary output setting or the automatic setting by selecting the 12 hour Flip Flop setting.
You can also choose to alternately power two lamps in the same grow room by choosing either the manual primary/secondary output setting or the automatic setting by selecting the 1 hour Flip Flop setting. This will be very useful to significantly reduce the ambient temperature of your grow room.
