I like that! I haven't seen one of these before. The ones in some of the rooms in my school are in a panel and has small black switches that flip from open to closed or closed to open. I believe its the same relay system as the ones used in some tech classrooms.

wow that's cool! Never seen something so complex for lighting before.

Yeah it's pretty neat but it can be a bit confusing for people who haven't seen something like this before. I've seen a a lot of TAs and professors fumbling with the lights when they put a Powerpoint on.

Why do you need a special setting for power points? We just shut the lights off at my school lol. It's cool that they made the lighting so flexible but seems like they must have had a lot of money leftover or something to use it on something as minor as lighting lol.

My elementary school had three rows of 3X F40T12 wrap lights(not end-to-end continuous rows, but the fixtures were on the same drop ciling t-bar) and three switches for the room. The left switch controlled the row of lights that were near the wall where the windows were. The middle switch controlled the light near the whiteboard (and only that light) and the right switch near the door controlled the rest of the lights, either five or seven lights.

My middle school's lights were just wired randomly to the switches with no rhyme to the reason. The original wrap lights might have been wired in an interesting manner but the troffers were just wired to two or three switches randomly.

My high school has a good amount about of variety of how the lights are switched. In the new C2 wing, which has drop ceilings and 2X4 3-lamp lensed troffers, has all 12-ish lights on one switch, which I dislike very much. Since they're three lamp troffers I would have liked to see them wired to two switches, one controlling the outer lamps and one controlling the center lamps. That way you end up with "3-way" fluorescent lighting.

The E-Building classrooms also have drop ceilings with 2X4 parabolic 3-lamp troffers which I think were originally T12, which would make them the only lights retrofitted during the T8 conversion. Anyways, those lights are controlled as I mentioned before, one switch controlling the center lamp in each fixture and the outer lamps controlled by the second switch.

Lastly, there's the rest of the classrooms in my school which look very barren and industrial with exposed beams, high ceilings, cinderblock walls. Those rooms have 8ft 4X F32T8 Lithonia wrap lights that don't even look like wrap lights lol. Those lights are all wired to two switches in every room. In some rooms, there's four lights, two on one switch (near the windows) and two on the other (near the hallway/door). In other rooms that are bigger, there are three rows of lights. Still two switches though, the ones near the windows are on their own switch and the rest of the lights are on the other switch.

My schools lights are all the same. Just your common Phillips and Sylvannia tubes. Some of our really old fluorescents in a few rooms are GE.

My classroom has a switch for the 6 ceiling fans, 4 for each row of lights, An old disconnected switch that was used for power shuton and shutoff. They use a huge box with a green light meaing powers on and a big red button for stoping all power. Excluding Ceiling fans and Lights. We have a switch for all the standard wall outlets. There are some dangerous ones in my class room though. The teacher wants to remove the old thin rod mounted between ceiling and floor that has 2 outlets together. He wants to have a outlet mounted to the ceiling with a extension cord that can run down from the ceiling to the work areas. If its not in the cinderblock wall then he wants to replace it with ceiling run down ext cords.

Hey atleast your teachers can turn on a projector and start a computer up...

This unit is so you can keep an eye on certain students.
