50w Mercury Lamp
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.

Nice!! I have a 50W merc that I want to try with a 40W fluorescent ballast.

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... Laughing
joe_347V   [Jan 05, 2014 at 01:55 AM]
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.
GEsoftwhite100watts   [Jan 05, 2014 at 01:58 AM]
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)?
streetlight98   [Jan 05, 2014 at 02:34 AM]
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).
joe_347V   [Jan 05, 2014 at 03:58 AM]
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.

I use my 400W MV to heat the room this time of the year! Cool
streetlight98   [Jan 05, 2014 at 02:17 PM]
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.
vaporeyes   [Jan 06, 2014 at 02:59 AM]
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.
joe_347V   [Jan 06, 2014 at 06:05 AM]
Yeah, I don't have any dimmed out mercs so I have to use a lower wattage to get less light Razz 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.
streetlight98   [Jan 06, 2014 at 11:08 AM]
yeah my only HID indoors is my street light stand in my room, which is pretty much an industrial floorlamp if you think about it. Laughing
GEsoftwhite100watts   [Jan 10, 2014 at 05:28 AM]
You're right! I've often thought that 400w MH highbay would make a good space heater, with useable light to boot! Laughing
joe_347V   [Jan 11, 2014 at 09:51 PM]
Well, it does make a good heater but I think 1kW MV is better Razz .

So any orders? Razz Laughing 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 Shocked

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.
joe_347V   [Jan 13, 2014 at 03:12 AM]
Can I place a order for delivery ten years later? Laughing Razz
