Emergency lights will stay on for at least 90 min, even when the building has no power. Allowing people to get out safely.

I enjoyed this class and learned a lot. The hands-on experience we had at the end really helped me understand the material that much more. I feel more confident keeping my techs safe and educating family and friends on how important E-lights really are, and how they work! which is really cool. Thank you for the class.
