I'd be interested in some. Even tho I don't have a ballast.. I wonder if I could run these off an electronic ballast of some sort...

I have a ballast. I bought a table lamp at Home Depot and a ballast on eBay like a year or two ago and converted the table lamp to 50 watt MV. I currently have 50 watt clear EYE lamps.

That's awesome! I did the same only with a desk lamp instead and it has a 100 watt sodium lamp.

Ah. Yeah it's at my parents house currently. I only ran it a few times. I talked to another member here before I connected the table lamp to a ballast to make it 50 watt MV. But I'm still concerned about the plastic 3 way socket.

I'd definitly convert the socket to metal or porcelain. Although I'm sure the plastic socket can handle it if it operates fine with 60 watt incandescents

The lamp shade is open on top too. So I suppose it ventilates enough.

I'd bring it to where you currently live and let it run for an extended period of time while you're nearby.

If everything seems fine.. Nothings burning and the lamp shade isnt blistering ly hot. I'd mark it safe.

It does ventilate quite well with a lamp shade, makes for shorter hot restrikes, too. The lamp holder gets quite hot, though, so I would at the very least use a porcelain one. Pulse rated would be the best, just in case you decide to go PSMH.

Do you have a picture of it ?

Yeah I wanted a low wattage HID that I could use for indoor lighting. It's not very ideal though. Clear MV isn't the best indoors it would be better if it was /DX but I wanted to see the arc tube lol.

I did some looking up on 50w Mercury lamps, the life span rating is dismal at only 8000 hrs for the eye brand, i sure hope they last longer than that in service. Maybe its longer on 40 watts?

Good find you have here. The closest info i can find is for the coated version and its rated for 16000 hrs which is great

Only if it's protected...you don't want that exploding in your house!

Your mission - should you choose to accept it - is to save unique and rare HID lighting before it's all scrapped.

Very rare to find clear GE 50w mercs! Outstanding find! Huge resistors in those things - they look to be as long as the arc tubes!

I wanted to convert my house wall packs to 50w clear MV...but the ballasts and lamps are hard to come by. I tried 100w for a few days but they were obnoxiously bright and used too much energy so went back to 35w HPS. Can’t have lights that are “normal” colors, you know.

I'm lampin...

Nice! I don't think I've seen a 50w clear in a brand other than Eye. I'm pretty sure I bought a 4 pack of 50w lamps from the same seller too.

35/39w CMH also looks pretty good for indoor HID and you can get them in 3000K and 4000K colour temps. I used to use them in my mini gumball before I converted it to 50w MV. Keep in mind you will have to swap the socket to use the bi pin style 35/39w lamps and they're also only enclosed rated too. Alternatively you could use the ones in a PAR20 or PAR30 form factor which are open rated and are medium base but look strange in something like a streetlight.

The 35/39w MH ballast (magnetic version) works perfect for 50w Mv for those who don't know.

It might just be from my experience but I found that 50w mercury lamps are a little brighter on a proper H46 ballast than they are on a magnetic 35w ballast.

Any machine is a smoke machine if you operate it wrong enough.

@ Lighingguy1994 : I think the rated life is at 40 w .

@ Joseph_125 : Along with the GE's and the EYE's I also have a Phillips : https://www.lighting-gallery.net/gallery/displayimage.php?album=5200&pos=49&pid=158120

The 8,000 hour rating for these lamps isn’t what it seems though, as it is a rating for a surprisingly low failure rate - 10% if I remember correctly, and only a small number of lumens lost. In reality I expect these are likely to last much longer in terms of MTBF, probably at least triple the stated hours.

I don’t know what control gear availability is like in the US but I’ve run them on UK 50W mercury gear just fine.

These are beautiful !!! I like the little sleeves that slide over the bases to warn potential customers about the specs ,

I believe the seller mentioned something about these

Hopefully that is the case as I bit the bullet and bought the clear 50w lamps. Eye is made in Japan and they are known for quality and workmanship into their products so my expectations for performance is higher.

H50 ballasts in the USA/Canada are very hard to come by nowadays, thats why I had to settle on using the 35/39w Metal Halide ballast as it is electrically compatible with the 50w lamps.

Thanks everyone ! Clear mercury vapor is my favorite. As a matter of fact I just ordered a GE 400w clear with the blue and yellow sleeve last Friday from eBay !

@ vintagefluorescent : "WARNING do not install in filament lamp sockets.read caution notice on lamp wrapper " And yes, these are beautiful, both lit & unlit!

@ Lightingguy1994 : i think you'll like the EYE lamps . The one I'm running dusk to dawn outside the back door has been flawless since I installed it almost 6 months ago !

Have you compared these to the modern EYE lamp? I'm curious to know if the color is the same.
