TechGrow’s Ballast Eco 2x600 is a relay-based lighting controller designed to switch two 600 W HID fixtures. It features an integrated 24‑hour mechanical timer with 15‑minute steps, enabling up to 48 on/off events per day. Three operating modes are available: clock (repeating daily schedule), on (continuous), and off. Intended for EU 230 V circuits, the unit is wall‑mountable and installed by plugging lamp leads into the controller and then connecting the controller to mains power; the manual specifies a minimum 10 A supply. The Eco series provides start/stop switching only—no dimming or sensor inputs—making it suited to straightforward, reliable scheduling of HPS/MH ballasts up to the stated load. The range includes 2x600W and 4x600W versions; this model is the 2x600W variant.
