The IIS Series "inverter system for emergency lighting loads," as its maker calls it with admirably scientific specificity, comes from IOTA Engineering — which itself hit the spotlight when NASA had it design and develop special high-intensity fluorescent lights for the astronauts aboard Skylab, the 1973-1979 U.S. space station. The IIS generators are designed to provide emergency power to multiple fixtures from an on-board battery supply, and can operate incandescent, fluorescent, LED, ballast and HID lamp types. They're available in three models: The IIS-125 and the IIS-375 are "interruptible" systems for 125- or 375-watt lights, respectively, while the IIS-350-U is "uninterruptible" for what the company calls "continuous, no-break transfer at 350 watts."
The series is UL-listed, naturally, and IOTA says the product meets or exceeds the National Fire Protection Association's National Electrical Code and Life Safety Code emergency-lighting requirements. Which probably means that the lightning bolts in the picture above aren't really real.
