HydroTek Lightspeed Flip Flipbox Flip4 Box 2000W 4000W 2 Ballast 4 Light. Condition is Used. Shipped with USPS Priority Mail.
Please look up what a flipbox does, this item runs 4 lamps with 2 ballasts on a timer, when the timer shuts to off - it moves power from the 2 that were on, to the 2 that were off. Meaning you can run 4000w in 2 rooms with alternating 12 hour cycles using just two ballasts. No returns, this item works and is rare.
