A transformer blew up recently and took out the power to a section of the street with our office. This happened while we were in the middle of assembling some computers for new employees. We needed to finish getting those systems put together so they had something to work on the next morning. Luckily, we had one of our Wall Pack 30W LED lights handy, with a battery installed so it could be used as emergency lighting.
Comparable to a 175W bulb, and lasting over 2 hours on a small charge it provided more than enough light for us to finish the setup. Speak to one of our sales people today to learn more about using our wall packs as emergency lighting.
