  • Ignition Control - The only ballast(s) that will ignite your lamps sequentially, one at a time, with soft start technology for true efficiency. This revolutionary safety feature prevents surges and spikes in your electrical circuit and prevents breakers from overloding. Whether you are powering up 10 or 100 units of Solis-Tek Ballasts, the electrical draw is controlled by our internal software for maximizing your electrical efficiency.

    This is especially important for automated systems to protect against inconsistency in lighting schedules.

    SenseSmart Technology - (Pre-Ignition Checks) - Solis-Tek ballasts will not ignite without a complete and proper connection. The ballast conducts a 3 second test of the connection circuit. If the circuit is incomplete ignition will be prevented in order to protect the lamp.

    SOLISBOOST OVERDRIVE: Contrary to industry standards, SolisBoost will only overdrive the lamp 5% more. We fine tuned the overdrive in order to prolong the life of the lamp and increase overall efficiency.

Love this product Review by jimbob
This is the best I've ever used. I've always used 400 watt but in the back of my mind I kind of think about going to 600 watt.
With this I simply change the bulb! Quit, cool and efficient.

Great ballast, quiet and cool running compared to a magnetic ballast and a lot smaller. Review by sunlight green
This is a great ballast and I highly recommend it with the solis tek bulbs, I'm getting great results using the 600 at 240 volts, only 2.5 amps...compare to a 400 on 120 volts uses 4 amps, runs much quieter than my magnetic ballast and a lot cooler. I can see the results are bigger and better and that is what I want.
