An Edge LED exit sign and a T8 18W fluorescent commercial emergency lighting near the door of the Storage of Carmel hospital

An Edge LED exit sign and a T8 18W fluorescent commercial emergency lighting near the door of the Storage of Carmel hospital

Both fixtures are made by Electrosen, Israel.
The LED exit sign are edge lit by ~8 white LEDs for visibility only, but eqipped with a battery for more 120 mins in the case of a power failure.
The upper fluorescent commercial emergency lighting for one T8 of 18W, is easily pales compared with my very more powerful Hyundai portable emergency lantern with its 24 5mm 0.1W high brightness white LEDs operates at full intensity (The lamp in the commercial one is underdriven on half intensity).
My portable emergency lantern also outperforms this commercial emergency lighting by battery supply time (Hyundai portable LED: 12 hours, Electrosen commercial T8: 120 mins).

I just noticed that the exit sign is hanging from a couple of screw eye hooks in the wall and is plugged into an outlet, much like I've done on my own setups here. I haven't seen that done on a commercial installation before, but I like it. Also, I've seen that same pattern on the diffuser of the fluorescent emergency light here in the US available as 2X4 flat sheets. I think Plaskolite makes it and sells it under the name "cracked ice." This would be the first time I've seen it shaped and formed into a wraparound like diffuser before though.

David, you are right. This exit sign hanged on the wall and plugged into an outlet. I don't know why they decided to hang it to the wall and not to mount it. But this may because they want easier maintenance. Generally, this exit sign can be hanged on the ceiling.
The commercial fluorescent emergency light is also plugged into an outlet.
Anyway, this storage are built up in the form of a commercial protected space, so the connection to the electricity can only be made by outlets and not directly.
