due to the generator running out of fuel, and since the lights were programmed start
notice how some of them stay on?

Why walmart's emergency generator was operated at all? Was there a power interruption?
Also why the lamps, which operated by programmed start electronic ballasts, flickered like preheat magnetic ballast and a glow starter when the generator was running out of fuel before completely went out?
What are the lights that remains on after the lights wents out?

A_lights:
I guess the power completely went out
the timing varies depending on how close to EOL the lamps are, the closer to EOL ones take a little longer to strike. making the lights randomly blink
i think the remaining lights were battery backup incandescents

dor123:
I see that while all of the emergency lighting in Europe and Israel uses fluorescent lamps and LEDs, most of the US emergency lighting uses incandesent lamps!!! why???
I never saw an incandescent emergency lights in Israel. Even when i was a child in the late 80', all of the emergency lighting were fluorescents.

For variety of reason why we have incandescent emergency lights in our market.  It is cheaper to build and buy incandescent emergency light.  In the past, they have used low voltage PAR floodlight.  Lately, they have been using patio light bulb instead...  It is not bright as the old PAR bulb though...
