The all new STK-1277 was designed and built for commercial use and for those with specific electrical requirements. The SolisTek DE ballast will operate any double ended lamp at its optimal efficiency. Compatible with both Metal Halide (MH) and High Pressure Sodium (HPS)!

The 1000w digital ballast operates at 277 volts @ 3.6A with an ultra high frequency of +100khz. The STK-1277 comes equipped with all of the safety features that SolisTek has introduced to this market such as Ignition Control and SenseSmart. These safety features detect if the lamp is too hot to strike, if there are any wiring faults or power disturbances, and will monitor load stability to prevent overloading your power on start up. The ballast operates both SE/DE further allowing greater flexibility from a single ballast.

An advantage of lower amperage is allowing for cooler operational temperatures thus lowering cooling requirements!


  • 4 step dimming: SolisBoost - 1000W - 750W - 600W.
  • Metal Halide (MH) & High Pressure Sodium (HPS) Lamps
  • 100+ kHz frequency
  • 277 Volt Only
  • Accepts Double Ended and Single Ended lamps
  • Soft Start Technology
  • Constant Power Factor 99.9%
  • 4.03A @ 277V
  • 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.
