Lithonia Quantum® LED Exit Sign (Emergency)
LQM-S-W-3R-120/277-ELN (White)(08-05)
Fixture's Information.
I have bought this at a local surplus store that sells used construction items. Sometimes they sell new items such as this sign. This sign was gonna be used for our church but it's too big where we needed it. So I kept it. Oh, well. I'll hunt down another one slightly smaller to use for the church. (Under construction so no big hurry on that search.)
Fixture's Size.
Here it is compared to a standard 12OZ soda can. Not that big as you might have thought they were. (Though it's bigger than we wanted...)
ID Tag.
Wonder why you can't find out what model these exit signs? Some companies put them INSIDE the signs so you gotta open one to see them. (Not advisable to try that in a public place where signs are found.) Some put tags outside where you can readily see what model it is and how old it is. (In this case it was made in August 2005 so it's 7 years old.
Lamp Included.
Here's the LEDs contained inside the sign. It sits on the bottom side of the sign. You will see why it's on the bottom side later.
LED Close Up.
Here's a close up pic of one of the LED itself. It's not one of your garden variety LED you see in your computer monitor. (Or pretty much anywhere.) It's a higher powered LED. This LED is called Piranha for unclear reasons. The LED is larger than your average LED. (Dome on it is about 3mm in diameter.
Lens Used.
One of the two lenses used on the sign. You get two of them in case you ever decided to make a double sided exit sign. (I've left mine one side.)
The arrows seen here are hidden by a piece of plastic which you can remove if you want to have it point toward the exit. I just left them on.

Back Plate.
Here's the back plate and its hole knock outs. You break off the plastic pieces in order to mount against the wall.
Ceiling Mount.
The mounting part. You can remove this part to use against the wall or move it to the side of the sign. (To use with two lenses on the wall.) Right now I have it set to mount on the
Internals.
Here is the guts of the sign. Not a whole lot of parts. Battery's in the upper left corner. The power supply is in the upper right corner. LEDs are on the bottom board. The battery's disconnected because if it's left on the LEDs stay on until they drain the battery completely.
Power Supply.
Here's the power supply after removing the white paper covering it. Not many parts in it. Just two big capacitors and a diode.
Power Connections.
This is where you connect your 120v or 277v power to the sign. Not a whole lot to say about it.
Battery Used.
The battery used in the sign. This is for powering the sign in event the power goes out. It's meant to last 1.5 hours. Might be less due to the battery's age.
Battery Connection.
Here's the battery connector and wire. You can see the LED on emergency power. Battery's almost out of juice. It's rechargeable so I am not worried about it. I leave it unplugged because I want the sign to be off not glowing dimly.
Power Supply Connection.
This is where the power supply is connected to the LED board.
Apparently I forgot to unplug the battery connection as one of the LEDs is glowing feebly. Oh, well. At least it's not overpowering the image. Heh.

LED Board Lit.
Here's the LED board lit up on 120v. Nice deep red glow. The Light in it is evenly distributed across the exit lens.
Lit LED Close Up.
Here's a close up of one of the LED lit up. Interesting internal reflections inside the LED's body.
Test Button and Status LED.
Remember the "Lamp Included" picture? This is why the LED board sits on the bottom of the sign. So the company won't have to make another board just for this switch and LED. Just use the same board.
This button is to test the emergency power. The button turns off the 120v incoming into the board. The LED shows that the 120v power is coming in. I press the button the green LED turns off.

LED & Button.
This pic shows the LED and the button without the sign's body in the way.
LED Sign Lit Up.
Here's the LED sign with the lens in place lit up. You can barely see the outlines of the arrows.
