I think also that we know how to improve emergency lighting. I believe the law is that they have to run for 90 minutes? At least exit signs do, I dont' know about those flood light things. But really, when they have been hanging on the wall for 10 years float charging a battery that has never been tested or maintained... What do you think the real runtime will be once the power goes out?

I completely agree. I used to work as security for a small hotel here. We had a bunch of those emergency floodlights on walls spread throughout the front office, guest buildings, and restaurant. One night, there was an extended power outage that lasted almost 2 hours. Several of the lights never went on, almost half of the ones that did go on did not last 30 minutes before going out, and only about 8 (of dozens) lasted for more than an hour.
Fortunately, no emergency arose in that time, and I had SOME personal lights with me /ubbthreads/images/graemlins/smile.gif, but the poor reliability of those rechargeable lights left much to be desired.
These buildings were all 3 stories high or less. It scares the cr*p out of me to think of a power outage happening in a high rise during an emergency.
God bless those firefighters, police officers, and emergency workers. Breaks my heart to read some of that testimony even now, 4 years later.
