At my middle school, the origional switch/outlet and wall plate combos appear to be almond outlets and switches with textured brown wallplates. That looks good IMO. Spot replacements have been very random though. I've seen black, white, and almond switches and outlets. I've seen metal, white almond, textured brown, and black wallplates. The outlets have slits in the nuetral part that make a sideways "T" shape. Are these 20 amp outlets?
-
My school used black devices with stainless steel wallplates. The outlets with a sideways T neutral slot are indeed 20A ones.
-
It seems whatever the electrician had was what got put up here. It looks pretty tackey. Some 3 gang wall plates will have 2 almond switches and one black one and the wallplate will be white. :8)
-
:8) I guess the electrician picked whatever was on the truck.
-
I guess so. :8) I noticed that a lot of the wraps have missign difusers here. It appears intentional, as only the ones in far corners of the school still have their difusers. There's antoher type of wrap too and every one of that type does have a difuser.
-
Fluorescent lights with missing diffusers looks kinda tacky IMO.
-
Yeah. I really like that design too. I wonder why they took most of the diffusers off one type of wrap and not the other. :-\ My school still has incandescent recessed can lights in the auditorium with clear incandescent lamps. There are some recessed cans outside the building, but I'm almost positive those don't work. i've considered donating some lamps as an initiative to service the cans, but I'm not sure of the wattage. There are some A19 shaped lamps and some larger lamps. I'm gussing the lamps are either 100, 150, or 200 watts. There are lots of older lights on the outside of the building that are forgotton. The mercury vapor wallpacks in the front still light up each night, but there are MH wallpacks around them. There's one post top that has a gross brown refractor and birds' nest too. It doesn't work, but I'm guessing it's MV.
-
My old high school has some old (probably late 60s) recessed cans with Fresnel lenses on them. Some of them were still incandescent but some had a corkscrew infestation.
The exterior was lit with a combination of HPS wallpacks, MH canopy lights over the doors, ~200-300w incadescent recessed lights, and a couple of MV bracket lumes.
The parking lot was lit with HPS floods O_o and the driveways were lit with HPS FCO shoeboxes and Powerlite B2255s.
-
There's a 1KW MH flood over the big parking lot, a 400w MH flood, a 250w HPS flood, a few merc wallpacks, MH wallpacks, and open bottom cans over the doors and in ramdom areas. No curly fry lamps in the cans here. :P ;D there are some in the main corrider in the wall scones. There are troffers in the main corridor too.
-
The last time I checked there was a couple of cans that had capsule CFLs inside...maybe they're even preheat.
The newer section of my school used to use F32T8 magnetic troffers but they retrofitted that to electronic IS. :8)
-
I'm not sure what my school's troffers used to hold. the troffers look modern, so maybe there used to be wraps in the classrooms. The hallways in my school mainly have wall grazing strip-like lights that run continuously down the corners on the hallway ceiling. Those i believe were always T8. all the troffers in my school are 3-lampers. The wraps are two lampers. All the ballasts seem to be parallel ballasts.
-
Most of the troffers in my old high school was replaced a few years ago except for the ones in the biology rooms which stayed T12 until last year when they were retrofitted with IS T8 ballasts and lamps.
The troffers in the hallway are four lamps while the old ones in the classes were 1X4s, the new ones in the classes are two lamp 2X4s. The office used three lamp 2X4 parabolic ones.
Note: I've split the last few posts from the light switches thread.
-
All the troffers here are 3 lamp lensed 2 by 4 troffers.

Oh boy memories!!!!!!!!!!
Most of my schools....had wraparounds I will try to explain it here later....I actually have a drawing of the exact ones in my middle school which was very unusual!
My Middle School built in 1965, the Gym was lit by incandescent! I think most of them were 500-1000 watters...not sure...but the lamps were HUGE!!! The high wattage were inside frosted and the smaller ones (along the small windows on the top) was lower wattage and most were clear incandescent.....although one got replaced with a small frosted....
My first Elementry school Gym had recessed mercury fixtures!!!!!!! ahhhhh although it was a newer wing of the school (probably late 70s....)
-
My elementary school was built in 1992. It had MH prismatic highbays with flat glass underneath. I believe they were GE's, but they're gone now. That school has motion sensor T8 highbays too. >:( The rest of the school has T12!!!! It's a newer school, so the stuff in there is still "good enough", so it wasn't updated. The cafeteria and library of my elementary school now had 3 lamp T8 lights in there now. The older 6 lamp 4X4 surface lights had all cracked plastic lenses so they needed to be replaced. tHe hallways are lit by 1X4 2 lamp F40T12 troffers with drop opal lenses. Yes- DROP OPAL LENSES! The aditorium has incandescent can lights as well, but there are PAR lamps in there instead of standard incandescents. The outside of the school has PL lights and HPS as wallpacks and MH for the parkign lot. That's the school with the Q-Tip lights.....
My middle school was built in 1970. I don't know what was origionally there, but the first year i was at my middle school, there was Lithonia CXD There was a total of 48 HID fixtures in the gym.

maybe you could take pics! That would be cool!!!! I wish I could go back in time and take pics of my middle school which was already renovated in I believe in 2002...

My elementary school was built in the late 80s and had 1X4 surface mount troffers in the hallways and the classrooms. The washrooms were lit with 1X4 louvered fixtures and the gym used rows fluorescents. All of them were F40T12. The library also has some incandescent recessed lights along with the entrances and the lobby. The outside used HPS wallpacks and MV shoeboxes (later changed to HPS floods)
The new wing of that school used T8 2X4 troffers and MH wallpacks.
My high school was built in 1968 and was expanded in the 1970s and in 2000
For the 60s and the 70s part of the building they used 4 lamp 2X4 troffers in the hallways and the cafeteria, while the classrooms got 1X4 troffers in rows. The gym was lit with rows of fluorescents and the stage with HPS highbays (probably originally incandescent). The workshops and the drama room got F40 turret industrials, while the display cases got single lamp industrials. The entrances were lit with high wattage incandescent recessed lights and the parking lot MV shoeboxes.
During the lighting retrofit the 2X4s got replaced with new T8 ones while the 1X4s in the classes were replaced with 2 lamp 2X4s with programmed start ballasts. The HPS highbays were replaced with CFL highbays. The turrets in the workshop and drama rooms was replaced with T8 industrials and surface mount troffers respectively. The display cases were later retrofitted to T8. The lobby had some incandescent recesssed lights and those 70s eyeball lights.
The MV shoeboxes outside was replaced with a combination of pole mounted floods, HPS wallpacks, MV Powerbrackets. I
m not sure when the HPS B2255 in front of the school was added. A second entrance was added to my school which used HPS shoeboxes. Some of the recessed incandescents in the entrances got replaced with MH canopy lights.
The newest part of the building built in 2000 used magnetic rapid start F32T8s, 2X4 troffers in the classes and 1X4s in the hallways and computer lab. These were all retrofitted to IS T8 and the original 3000K lamps changed to 4000K ones. The outisde used MH wallpacks.
-
if the highbay was HPS....most likely they were installed in the late 70s onto the 80s.....due to energy crises!
-
HPS highbays? :o Ick! >:( I can't get pics of my middle school as easily because they DO NOT allow ANY photo taking in the building for soem reason (privacy of students maybe?) Only the yearbook staff can take pictures and those are strictly for the yearbook. My elementary school, I'm sure i can sneak a few pics. My little brother Scott goes to that school now. I don't know when I'll be back there again, but it'll be at one point.....
-
Those HPS highbays were the worklights on the stage but I guess those fixtures MIGHT have been MV or incandescent originally, during a performance the stage lights were used instead. Mike that's where cellphones would come in handy.... (http://fc05.deviantart.net/fs43/f/2009/100/c/2/whistling_smiley_by_Broni123.gif)
-
Trust me Joe, they've solved that too. They'll give you 2 one hour detentions if you use your cell phone on school property, never mind in the building! :o
-
Well, the locker room is lit by lensless 2X 32w wrap lights.
-
The stairways in my school were lit with 2X4 troffers in the old sections and 4' narrow wraps in the new section.
-
The wraps here without lenses are the standard commercial grade wrap lights. The wide curved basket wraps all have the lenses though. I'll try and sneak a camera in. If i'm careful, i won't get caught. Some of the teachers don't mind use using our "electronic devices that take away our learning experience". If i'm around the right teachers at the right time, I can get some pics. ;D
-
here's our full disipline handbook (http://www.cps.k12.ri.us/whills/Discipline%20Policy%20New.htm) :o :8) >:( :o
-
The problem is if like most schools the administration will most likely turn a blind eye towards any complaints. But the problem is now worse because you can't like you said fight back.
-
In my old school you used to have only 2 minutes to get to the bathroom, use it, and walk back to class. They were strict on that! I don't know how many detentions I have gotten from being 4 or 5 minutes. Never went to one detention :P They said the "bathroom" is a privilege, not a right.
Well, try telling that to some people other than me :8) "Nature Calls" ;D
-
I don't think my teachers cared that much about people taking long washroom breaks, a lot of people used to take 15 min breaks. :o
Funny thing the oldest style of fixture I've seen in a school were those louvered fixtures, I've never seen a school with those Saturn lights or half pipers.
-
I don't know how old the lights at my school are......
-
Usually you can tell from the ballast or the fixture tag.
-
Exactly. There are tags on the lens-less wrap lights. Maybe i can try to look at one. I can almost make it out with my glasses, but not quite.... Possible taking a photo of the tag and zooming in on the image later will help me. You know how my camera is though.... The wraps do look like their from the 70's
-
Or if you catch someone replacing the ballast you could try to match it up with the ones on here.
-
All the ballasts have been retrofitted, so that wouldn't provide any info exept when the retrofitted them. The ballasts are isntant start, so they must not be origional since the public school department is way to cheap to have bought electronic ballasts on the 70's.
-
Then tags would be the best bet then.
-
I think the curved basket wraps are Holophane, since someone either here or on the L-G posted a pic of the exact same type.
-
Any soot marks inside the lumes, that's often a tell tale sign of older fixtures.
-
There's soot in the lensless wraps. The tags look 70's.
-
You can also approximate a fixtures date from looking at the UL logo too.
-
IIRC, the tag is metal with blue ink. If there's a bad ballast, it's fixed, but if the socket melts, etc, it's replaced. i only know of one wrap in the whole building that's been replaced. It was in the muic room hallway.
-
Hmm I've never seen a fluorescent fixture with metal tags before, must be a older fixture.
-
I THINK they're metal.... The tags are on the side of the fixtures on the left.
-
Well if the tags were paper they would most likely have yellowed by now.
-
I don't remember that clearly since i pass the tags very quickly most of the time.... I'll check tomorrow and maybe i'll get some pics! :o :D
-
Well of course a pic would be better. :P
-
I got pictures!!!! The good news is I didn't get get caught. :D The bad news is that my selection is limited and i was unable to get a good shot of the label. :( It turns out it IS metal, but it's black ink, not blue. The only part I had time to read was either "PRIMELITE" or "PRIMALITE". I'll do the best I can to write down whatever else I can read, but becuase of shadows, I can't get a pic of the tag. I did get a pic with a tag in the pic, but it's unreadable from the pic. :(
-
Hmm never heard of any of those brands before, [cough] you might want to try asking on the other forum too, there's a lot more fluorescent discussion there.... [/cough]
-
I found out PRIMELITE does make (or at the very least distribute) commerical fluorescent lights. Not sure if its the same company though.....
-
It's possible, I've found some similar results too...
-
My technical high school has quite a nice variety of lamps being used. Aside from the F32s that are common as dust, there are several rooms lit with 400W probe start MH high bays, some recessed cans, exit signs in both converted and original configuration, etc.
I could do a complete list, but it'll be quite long to do ;D
-
There are some PL Handicapped acessable signs here too.
-
OK, found out the "PRIMELITE" wraps are "ALLIED FLUORESCENT MFG CO" and the family or model of the wrap was "PERMALITE", not "PRIMELITE", as I though before.
-
Did you try a google search?
-
Yep, and got nothing. :( :-\ I remember reading "118 vac fluorescent fixture" on it, but that's pretty obvious stuff. Maybe I'll bring bi-noculars just for the heck of it lol. I couldn't read all of it even with my glasses on and it about 5 feet in front of my and about a foot higher up than me. I'm not done until I record every word and make an electronic copy of one of those tags. Maybe I can find a away to get one of those metal tags.You never know if they have soem spares lying in the back from when they took most of them down to replace with troffers. :MV:
-
I would try checking out the shop classes or the store rooms, that's where they usually keep spare stuff.
-
The janitors share an office with the boiler and generator in there. They probably have soem maintenance items in there like taken down fixtures, lamps, nuts and bolts, etc. There are also plenty of doors marked "COSTODIAL CLOSET" that are hallway-like rooms that contain breakers, fire extinguishers, wet floor signs, etc. When i can get some extra time, I'll get my notbook after school and copy a tag the best I can.
-
I think my old school had a similar arrangement....
-
Yeah. Breaker boxes are very ramdom in my school. Some classrooms even have padlocked breaker boxes. :o
-
My old school used to have breaker boxes in the hallway and some of the science labs had breaker boxes inside the too. Some of the breaker boxes in the science room were left conveniently unlocked too. :o
-
Almost all the breaker panels in my old high school were unlocked XD In my current school (and especially in our two workshops) most are unlocked as well.
-
Almost all are unlocked, but I've recently been seeign locks appear on the ones in areas accessable by students. The ones in the computer rooms are unlocked though. Every four computer runs off one breaker. That's only two gangs to a breaker! :o I wonder how much power they thought a computer drew.
-
It really depends on the processing power and how many extra peripherals are inside. I know of high end gaming desktops that need a 20 amp socket in order to run. :o
-
Wow! :o That's a lot of power! The ones at my school are Dell desktop computers with LCD screens and Intel inside. The outlets are ORANGE and have the "T" shaped nuetral, so they're 20 amp outlets.
-
The orange outlets are isolated ground outlets, basically they have a extra ground wire (one is connected to the metal box and framework while the other is connected to the ground prong).
-
Is that just for extra protection or is it needed under certain circumstances?
-
I believe it helps prevent noise and interference from affecting sensitive electronics.
-
Ahh. I wonder how it does that. :incandescent:
-
Ahh. I wonder how it does that. :incandescent:
Well it obviously doesn't use a light bulb. :P
Try reading this (http://www.mikeholt.com/mojonewsarchive/GB-HTML/HTML/Grounding-versus-Bonding-Part-9-of-12~20050602.php) or asking the same question on L-G. There's a lot more objective and technical discussion there.
-
Ahh. I have a better understanding now. Thanks. :D

my old elementary school in Atascadero, California had t8 troffers in the classrooms, some two lamp, some more in the modular classrooms that were added later. HPS recessed square fixtures in the hallways, t8 single-lamp fixtures in the bathrooms, HPS wallpacks, a few strip lights, also t8, and everything flourescent was instant start. I am the same age as Mike, and I last went to that school in 2008. There were more fixtures but I'll make a list of what I remember and maybe make another post. My new school runs entirely off a generator, since I live in a remote Alaska town of about 30 people. Anyway it is entirely f40t12 and a few HPS lights outside and in the gym. I gave the school a bunch of vintage norelcos and GE mainlighters, and the first norelco went in recently. ( I an 14, but help maintain the lighting.) The school has t12 surface mounted 1x4 troffers inthe original 1970s single classrooom(it's a small school) and a few wraparounds in the hallways. The 1984 addition has exposed striplights with reflectors on the top half to direct the light downward, and these weird wraparounds in the classrooms that are two lamp and have opaque lenses that are white plastic. The only thing that looks ugly is that someone did spot replacement and has regular cool whire lamps mixed in with GE "chroma 50".Looks strange. Also, when ya first turn them on, they buzz loudly and the 34 watt lamps start out dim and ugly. No, they are not Alto, but GE wattmisers new enough to have the hg logo. They are being replaced by the janitor and I with true 40 watters. Much better! The school has a combination of chroma 50 with the old GENERAL (GE) ELECTRIC etch, wattmisers that are not ecolux but have the big meatball, true value lamps, westpointe lamps, Sylvania cool white plus, and we just atarted on the Norelcos that the city hall was throwing away when they went to t8. Everything, and I mean everything is RAPID START!!!!! The restrooms have cool lights, will try to get a pic made of prismatic diffusers and wooden sides. The ballasts run the lamps in series I think, because when one lamp goes bad both go out or dim, sometimes only one staying lit. Sometimes when a 34 watter dies, it will glow dimlty at one end, (because the electrode on that end is okay?) Anyway, I am proud of this installation!
