SolisTek ballasts, the electrical draw is controlled by our internal software, maximizing your electrical efficiency. Soft-Start technology is standard in all SolisTek Digital Ballasts. SenseSmartâ„¢: Pre-ignition self-diagnostic checks, which will check for 8 different factors before attempting to power the lamp. SenseSmartchecks for: Open Output, High/low temps (internal), Ignition Failure, Thermal, End of Lamp Life, Overflow Current, Over/Low Voltage, and Short Circuit. Solis Boost Overdrive: SolisTek's overdrive does not harm the longevity of the lamp. Contrary to industry standards, Solis Boost will only overdrive the lamp by 5%. Because STK ballasts are rated so efficiently, the extra boost in power will not affect the lamps' lumen depreciation or shorten lamp life.
