Osram 2000W HQI-T Metal halide lamp at full power

Osram 2000W HQI-T Metal halide lamp at full power

Click to view full size image

as I mentioned in a comment on Max's Concept lamp picture, I have 2 of the 1Kw M47 ballasts pictured in my gallery, which when put in parallel let me run up my 2Kw Metal halide lamp to full power finally :)

and oh boy is it extremely bright! :)

this 2Kw Lamp normally requires a ballast which requires 415V 3 Phase mains power which I sadly dont have in my home, so im quite happy to have gotten the right gear to to enable me run it to full power with my 240V 50Hz mains, I am aware the lamp was made for horizontal burning however I could not figure out a safe way to run it so within the confines of my workspace

I think that this lamp intended for horizontal burning position, because of the long arctube.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

Have you even read Bulb Freak's description above, dor?

Bulb Freak - Thanks for posting. I also have the same problem running 2 kW MH lamps of this kind as I don't have access to 400 V mains at home (my parents have it, but it's 450 km away lol). Your use of two M47 ballasts is a good idea. Are those designed for 50 Hz operation or are you using standard US 60 Hz types?

To comment on how you run your lamp: when I visited Osram's factory in Molsheim, France, back in 1989, in their labs I saw that they tested some of their 2 kW HQIs in the vertical position. I even saw one running up close, those are really bright indeed. I wouldn't be too much worried if I were you, the lamp will be just fine if you don't use it permanently in this position.

I read the description, but not noticed that Bulb Freak was aware about this. I have difficulty reading text in the recent times.

thanks for the comment max its very cool you got to visit the factory, (I always wanted to visit a lamp factory, maybe someday I will ) although im not aware of 2Kw Osram MH lamps being made in France, do you know what they where testing with them over there?

I am using 2 very rare 240V 50Hz British made HX autotransformer ballasts which you can see here https://www.lighting-gallery.net/gallery/displayimage.php?pos=-145508

I also have a picture of 1 ballast running a US 1Kw Philips M47 lamp I bought in israel many years ago https://www.lighting-gallery.net/gallery/displayimage.php?pos=-145507

(I was hoping the ballasts where CWA, as that would of let me adjust the current by adjusting the capacitor value, but testing I have done indicates that they are HX ballasts, so to run my 700W Westinghouse mercury vapour lamp ill have to continue with my 600W SON choke+Center tapped variac=homemade autotransformer ballast setup)

indeed I had figured a short running in the vertical position would not do it any harm, and at worse the colour stability would not be in spec

(as a side note, I started it on 1 Ballast then switched the second ballast in about 15 seconds later, as I imagine with both connected at startup the inrush current would of blown the 13A fuse in the wall plug I was using)

I didn't know that you bought a US Philips 1000W M47 lamp during your holiday here in Israel. You could also buy an Eltam M47 autoregulator ballasts for your lamp.

Trust me I tried sadly it was not feasible (I did however bring home an Eltam 110W Rapid start F96T12/HO ballast )

Those Venture ballasts are really nice, I wish I had a couple of them! On the subject of your 700 W Westinghouse lamp, try running your M47 ballast on a variac at a lower input voltage, you might be able to reduce its output current to the desired level (3.25 A).

"im not aware of 2Kw Osram MH lamps being made in France" - They are not, Osram's Molsheim factory produced incandescent lamps only (I think they do some LED filament lamps now). Interestingly, they had quite a large test lab there where they worked on HID and fluorescent lamps as well.

indeed that is something I have been thinking about trying, just a little reluctant to do so, given the rarity of the lamp, (plus I have a feeling the lamp may extinguish due to too low an OCV before the current drops low enough, IIRC a 700W H35 MV lamp runs at 2.8A rather then 3.25A, which is the current for a 400W Mercury vapour lamp https://eyelighting.com/wp-content/uploads/HID/Mercury/spec-sheets/HF700PD.pdf )

You're right, the H35 lamp current is 2.8 A, not 3.25 A, my mistake. In this circumstance a too low OCV from the ballast is indeed a real risk. Test this nonetheless, those MH ballasts have a high OCV-to-running voltage ratio, so it might still work. If not, start the lamp at full ballast input voltage (or close to it) and then reduce it to the desired level, this will certainly keep the lamp running.

geeza I forgot my sunglasses viewing this pic

No LED gadgets, spins too slowly.  Gotta  love preheat and MV. let the lights keep my meter spinning.
