50w M-E DTC mercury lamp I found at Restore. It's shown here running on a 40w fluorescent ballast so if I find a real 50w merc ballast it might be a bit brighter. Right now it's around slightly brighter than a 100w incandescent.
The base is stamped HUNGARY 09 87...I'm guessing Sept 1987 from Tungsram?
Nice! yeah i think it should be a little brighter than a 100W incandescent. IIRC MV lamps are either 2 or 3 times more efficient than incandescent but i think it's 2X
Thanks! I think that's why the 50w mercs haven't really caught on since they're only slightly brighter than a 100w incandescent.
The thing I like about it being dim compared to other HID lamp is that I can run it in my room without racking up the power bill. And plus it dosen't blast my room with too much light like 175w lamps.
175w clear MV was just perfect for my room but a little bright if you were looking right at it of course...now when I fire up the 400w MH occasionally...
Yeah, a LPF preheat ballast would run these. If not a 50w MH ballast or a 35w MH ballast would also work in a pinch. Make sure you disable the ignitors though.
For a 75/80w one would a 2-lamp F40 RS or preheat ballast work? What about a F96T12 ballast? I know a 215w VHO ballast will run a 175w MV...is the opposite true at all? (Aside from cathode heating as they're rapid start lamps)?
I find that 175W MV lights my room really good (a little on the bright side though) but the heat from the 175W fixture is really a lot with either my OV-10 or M-250R1. I like my room to be on the cooler side (62-68 degrees) so i typically shut my heat vent unless i get too cold (i have forced hot air).
I find 100W MV lights my room well too and it doesn't get nearly as hot. After a couple of hours my M-250A is only fairly warm on top (the glass is sorta hot but i can hold my hand for a couple of seconds before its too much).
Yeah, 175w MV lights my room pretty good but it gets kinda hot in here. 100w MV is better but I like how 50w MV is dim enough to get that MV mood without being too bright.
yeah if i'm in the mood for not a lot of light i stick one of my BT25s in (either my sylvania or Westy lifeguard /DX lamps) since they're both about the same brightness and create a nice dim glow like moonlight.
A 50w /DX mercury is about the same brightness as a 100w incandescent. That size is the least efficient of all HID lamps.
I have a lot of HID fixtures in the house as accent and/or ambient lighting. Clear mercury & HPS are particularly interesting for the colour they put out.
Yeah, I don't have any dimmed out mercs so I have to use a lower wattage to get less light I usually try to stick around the 100w, 125w, 175w wattages for indoors.
Ahh, yeah I guess lower wattage HIDs are less efficient to begin with too so it being the same as a 100w incandescent is reasonable. Don't have a lot of permanently installed HID fixtures inside though aside from a 70w CMH uplight in my room and a 175w yardlight in the garage.

So any orders? I meant for it to be a completely outrageous price, but after calculating it out, $7980 is actually pretty reasonable for twelve 2000W MH sportslights with lamps, a wall mount bracket, a 120 to 480V step up transformer, and a cord. lol
And now that pot is legal in Colorado I could also sell a similar 12X 1000W MH/HPS version called the McCann Lighting Gro-Lume 12000 lol.
