Advanced Technology

Ignition Control
Solis-Tek is the only ballast that ignites lamps sequentially with a soft start to eliminate electrical surges. Whether powering 10 or 100 units, startup draw is regulated to prevent tripping breakers or harming sensitive circuits—making this ballast automation-ready.

SenseSmart Pre-Ignition Checks
Before powering on, the ballast performs a 3-second diagnostic of the connection circuit. If the circuit is incomplete or unsafe, ignition is blocked to protect the lamp and system.

Pre-Ignition Safety Checks Include:

• Open output

• Short circuit

• Ignition failure

• Overcurrent/low current

• High/low temperature

• Thermal failure

• End-of-lamp-life detection

• Over/under voltage

SolisBoost Overdrive
Unlike other overdrive modes that can shorten bulb life, SolisBoost gently increases output by 5%—fine-tuned to boost performance without compromising efficiency or lamp lifespan.

Ready to Power Your Garden

Whether you're running a single tent or a full grow room, the Solis-Tek 400/250W Ballast offers smart, safe, and scalable performance that meets the demands of modern cultivators.
