May 15, 2020 – Operating from either standard AC or up to 280VDC, a new LED bulb from Irwin Industrial (along with its partner VCC) promises to eliminate inverters, simplify wiring and increase reliability in emergency lighting systems. The 9W AC/DC bulb replaces 100W incandescents while maintaining the standard E26 base and A21 shape. It is also approved for use in fully-enclosed fixtures. In case of emergency, DC can be supplied directly to the fixture with the same gauge cable as the AC. The higher efficiency allows for a 10x increase in emergency lighting time.
