Very cool. I took my 250 watt metal halide fixture of my shop and put in a mercury vapor bulb. Takes me way back to childhood when seeing mercury vapor street lights, gas station canopies, and some gyms and indoor pools.
problem i have with all the HID lamps that use the medium base socket is they're too short for these fixtures.. The bulb is too far into the fixture itself, so 30% of the bulb is inside where the aluminum reflector is. This causes the lense on the last few inchs of the fixture to look darker because its not getting the full bulb to spread the light. Its like this on the medium base HPS and metal halides as well. I have 4 of the HPS medium base pole/security lights (two 150 and two 70w) like this one you have. And all the bulbs are too short. so alot of light is wasted. being so far inside the fixture it reflects off the aluminum top and just points straight down. You want the light to point outward. I have 3 100 watt Mogul base HPS lights. The real ones you see that power companies installed on their poles at people's properties etc. Those lights with the mogul base the bulbs are so large they are down further in the fixture so the lense gets fully covered in light. The light spread is much further out than that of the 150w i have. Yes the 150w is brighter, but the spread isnt nearly as far because of the shorter medium socket bulbs. Im also a firm believer that the shorter arch tubes on the medium base HPS and MV and Halides, also creates less light overall, a medium 150 and a mogul 100.. On paper the 150w puts out 16k lumens, and the 100 is 9500.. but the longer tube in the mogul base light means more light. Maybe not as bright as the 150.. but more light over all. Same with the newer mercury vapor lights.. how does a 175w mv with a shorter arch tube put out the same light output as the older 175w with the longer arch tube.. because of this i am in the process of replacing the 150w HPS lights i have with the 100w ones that my friend from the power company is giving me. not only Saves power, not QUITE as bright right near the fixure. but light spread is much greater. So in the end i dont notice much of a difference in brightness tbh.. I litterally have both running 150 feet from eachother and if i stand in the middle and look left and right and repeat i see no real diff between the smaller 150 medium and 100 mogul.. also not sure a clean arc tube means low life.. I have 175w bulbs that are 20-30 years old in fixtures that are 50 years old with no switch to turn them off 30ft up a pole.. Only way to get them is a bucket truck.. tube looks clean.. no black very little if any white, but the lights are half the brightness of brand new old stock westinghouse and GE bulbs.
Yes these 125w MV fixtures are hard to find. In fact this one doesn't have a true 125w MV ballast, it's actually a 100w MV ballast. I do have one true 125w MV fixture, it's made by American Electric.
I'm wondering now if the later 125w fixtures like this one were a way for the manufacturer to get somewhat longer life out of cheap non-name-brand mercury lamps by underdriving them. I know the last generation of Regent 175w mercury yard lights had undersized ballasts and would drive the lamps at only about 125w, so maybe your ballast is only powering 125w lamps at 100w. Opening up Regent 80w, 100w, and 125w fixtures....the ballast labels on all say H38, but they don't all seem to drive a 100w lamp at the same wattage when measured, which is curious.
I have a few of them I found out the bulbs didn't last very long. Because it didn't have the little support indent in bottom of bulb to support arc tube. The vibration shake them apart. So I unhooked ballest and just put a regular bulb in them and still work very well.
Thats funny that it is marked H38/125w mc, H38 lamps are 100w mv while the ansi standard for 125w MV lamps in the US was H42. You might be able to get away with running a 100w lamp in there as i think the ballast is just a rebranded 100w mv ballast. I do have an H38 regent ballast just like that one somewhere that while shorted, it des state it works with 100w MV.
i have HPS fixtures like this, I have 3 50w HPS wall packs.. The box says 50w, the bulbs are 50w. but the ballast sticker on every fixture says ( replace with 35w hps bulb only) The markings on the ballast also say 35HPS on it.. Yet the fixture is 50w and bulbs are 50w. So either the ballast has the wrong stickers.. Or yea.. They are a Grandelite made in usa new old stock i bought 2 months ago made in like 94 i think.

That's awesome, mercury vapor light definitely has a wonderful feel to it!
@@Parrot175 Here’s a video I did of all the HID light fixtures I hung in the bay entrance to my shop. ruclips.net/video/cSmXfczidzw/видео.html
Very beautiful enclosure, nice find!
Thank you!
Interesting little fixture. I've never been a fan or these hardware store style luminaires but the fact that this one it 125 is very unique!
Thank you!
@@Parrot175 hi
That fixture is so beautiful!

theres one of those on my houses garuge outdoor light
Could you show this fixture turning on with a life a lifeguard a21 shape Mercury vapor bulb?
Interesting
Awesome
i always see theese lights
youre seeing the 175s most likely they look identical not the 125
