Where are traditional EXIT signs placed ?
High above the door and ceilings.
Then why do most codes require they be located near the ceiling when smoke would obscure them and render them useless?
Tombstone Regulations are basicaly waiting for people to die before requiring improvements in codes and regulations.
One of the worst fires in the history of Las Vegas occurred when an out of control kitchen fire spread to the ventilation system of the famed MGM Grand Hotel.
Las Vegas learned from this tragedy and eventually required all hotels to require low level exit signage. If you walk down any hallway in Las Vegas you can see the results of these tombstone regulations. Why are virtauly no other buildings outside of Las Vegas not following their lead ?
It's great that low-level EXIT signs are installed but traditional electric EXIT signs do have some drawbacks.

Because they are UL listed they can both replace traditional electric EXIT signs and they can also be used for low level installations. TheAdvanced Photoluminescent Technology® utilized by MN8 Foxfire signs will glow for many hours, thereby illuminating your way to safety. The extremely low profile signs mounts flush to the wall and very durable. They will last for decades, have minimal installations costs (no electric needed) and most important they are fail-safe.
