Sometime back in the late 1970s I installed an emergency light in the hall by the basement stairs, and I'm thinking it was a Dual-Lite EZ-2. It lasted for about 8 years before the battery went bad. As the battery was about as expensive as a complete unit, I decided to replace the fixture. The new one was an earlier version of the Lithonia shown in the original post. I used it until I started the renovation several years ago. I still have it packed up, but I imagine it would need a new battery.
It's not necessary to have an obtrusive emergency light. There are regular fixtures that have emergency lighting function as an option. These include a battery, inverter, charger, and test button as part of the package.
