These were so nostalgic to my childhood because of when I was in pre school they had these lights in the cafeteria and they used to let me turn them on
i remember in my elementary school my librarian let me turn on the 2 preheat pl can lights at the shelves and sometimes also the lamp in the computer area.
At the fish collecting place they only use these lights, and at the wall outside the building, they somehow can install a wall mounted mercury vapor street light at the wall, one was replaced with HP Sodium. And inside a office they use preheat fluorescent, but some of them were used as led bulbs on a preheat fixture
My school has two gyms and one of them uses fluorescent tubes while the other one uses metal halide bulbs but the fixtures themselves are completely different from these. Half of the fixtures have bulky covers while the other half have flat lenses (possibly due to the covers melting from all the heat the bulb generates). Four of the fixtures got replaced with LED and one fixture had it’s bulb changed to run a sodium lamp! Most of them give out different light outputs which is pretty cool.
My Elementary school had Metal Halides in the gym when I was there, and they hardly burned out as they seemed to cycle all the time when they needed to be replaced, and several years ago they were all changed out to Fluorescent High Bays!
I remember seeing Metal Halide fixtures exactly like this in an indoor soccer field many years ago. I mainly am into elevators but I like lighting some which I have two cheap industrial fixtures at my house.
in the workshop at work we have high bays they are 400w each and there is 40 of them. thats 16000w :O they are prety good, in the mornings I am usually the first one in the workshop so i go aroudn turning them on, the ballast sound brilliant
Cool! at my old school they only used Mercury Vapour lamps in the big Hall where we used to play inside sports or have drama classes The fixtures had no covers they were just shielded inside an open aluminium dome I asked the caretaker what the wattages of those lamps lamps are & he replied I think there 200 watts each if I can remember there were 14 Mercury Vapour light fixtures in the hall
I looked at some spare fixtures stored away (of the same type) and found that they are 250watt MH and are 208volts. The big ones are made by Day-Brite.
Love them! I have 3 fixtures that look identical to these, mine are 400 watt so i bet these may also be, the bigger ones at least. I don't have the smaller one although I want some. Great video.
There's a shop in my town which uses some industrial looking lights which producing similar light like these, but the sound they producing... Well, the actual sound is not humming - a little hard to describe it - but it sounds like the filament is resonating in the bulb or something like that... Quiet and pleasant sound... 😏 💡
Do some lights like those have a halogen or some other type of bulb that’s turns on while the metal halide bulb warms up, then turns off when the bulb is fully Powered?
the larger fixtures look to be 400 watt, and the smaller may be 250 watt, both with reflaectors on the dome and what looks to be s glass or plasic refractor
He could have been right or wrong but there is no way of finding out now because my old school was demolished a few years back to make way for a new bigger school That school was almost 100 yrs old i think it was built in 1908
in my middle school, they use 400 watt mh fixtures in the gym. there are NO covers on the bottom and some of them have mold on them. whenever i play a game in gym, the ball always gets missed by a couple inches from hitting the light!! and also i have seen 2 fluorescent bulbs already burn out in the cafetiria!!
Some kids was playing football in the gym and one of them kicked it so high it got stuck on the ceiling so then the teacher tried to kick another ball up there to get it down but he accidentally ended up hitting the light fixture instead and the cover fell and broke.

These bulbs have their own startup sequence just like a computer

They also should’ve had coated bulbs for less glare. Clear metal halides are not good indoors.
I remember seeing these lights in home improvement warehouses!!!

How did you feel about them replacing them?
They were probably white hps because hps are the only ones that cycle

I recently took one like the smaller ones down at a job and it was 250w i think the brand was Cooper.
Yeah my elementary school use to have these inside
the gym, and lunch room.
0:19 that one on the far right light Mercury was vaporizing slow

Looks scary if I am there alone
Boo!
I love that Metal Halide fixture and the nice sound of the transformer, it reminds me I was in the warehouse or in the big garage. =)

That looks like another level of the Backrooms. (even with the buzz)
Back rooms use Fluorescent Tubes which are similar tech, but yeah, backrooms with either Metal Halide or High Pressure Sodium lamps would be cool.
I’ve always loved these kind of lights. They kinda look like the HMAO R series of the Holophane High mast

Actually I am not, that is just a banner hanging in the shop.
Arizona mills mall has a few of the 400 watt version of those lights in some of their stores.

That depends on the fill gas...some of them, particularly ceramic ones, have a xenon fill gas which strikes with a bright white color...
Do they still have those high bay lights their ?
I think they are POS LED COB lights now
@@tearimakatekeimoa1675 Eww, Cob
Are those Mercury Vapor?
Please reply!
No, they are metal halide. The video title says so.
Halide buzzes louder than Mercury Vapor
Do some lights like those have a halogen or some other type of bulb that’s turns on while the metal halide bulb warms up, then turns off when the bulb is fully
Powered?
Thanks for the help

Do you know if these are probe-start or pulse-start?
I think I saw some at the gym in High School, I think I have a video showing them back in May 2012.

My schools gym use to have these but they got replaced to years ago with floresn't lights
Coolgarrett02 Productions same
yep, same
fluorescent
sorry to hear that
At least they didn’t get replaced by LED.
@Parrot175 which high school that you had already filmed that has the low bay light fixtures in your high schools auto shop.
Metal halide lamps light green while they're warming up. Sometimes they also do funny red flashes.
in my middle school, they use 400 watt mh fixtures in the gym. there are NO covers on the bottom and some of them have mold on them. whenever i play a game in gym, the ball always gets missed by a couple inches from hitting the light!! and also i have seen 2 fluorescent bulbs already burn out in the cafetiria!!
Techmatt167 have you ever got one before
Hit one before ?
Some kids was playing football in the gym and one of them kicked it so high it got stuck on the ceiling so then the teacher tried to kick another ball up there to get it down but he accidentally ended up hitting the light fixture instead and the cover fell and broke.
@@SuperMarioAutist what kinda cover was it was it acrylic lens or was it glass
Why weren’t the bulbs coated?.
W O W !!!! THAT"S REALLY KOOL-ASS !! .......
Yes!
The small ones are 400 watt and are made by hubbel the old version
So you're studying at Wyotech, hows that working out for you?
I think he meant 250watt, they don't make 200watt MV bulbs.
Oh but they were green up until they flickered then they were pure white
Well no not really cycle, but yes I have, they just glow a dark purple.
did u see me vid of hps high/ low bay lights turning on?
Where is it??!!!
I think they are all 400 watts
0:59

metal halide 400w
Dead flyes
There all 400 watts
