My OV-50's former home

My OV-50's former home

Click to view full size image

This is the former location of my 700w Ov-50 I've known about this for almost 25 yrs but could never figure out who owned the car wash it was located at. About a year and a half ago the car wash sold and I saw the new owner there making repairs and offered to buy this and the 2 M-400's on site and a few weeks later I got the call " they're down, if you still want to buy them" I was there in 5 minutes with money in hand !

I figured the OV-50 was "just" a 1000w MV, I almost had a heart attack when I saw the "use 700w Mercury Vapor Lamp" sticker inside !

Wow. What an easily salvageable light fixture. I would have quickly rescued that fascinating light fixture.

Awesome! So cool you have a 700W MV fixture, though I'd personally rather have the 1000W since the lamps are easier to find. For GE, they used the same CWA ballasts in both the 700 and 1000W fixtures. They just used a lower value capacitor for the 700W lamp. I'd guess others did the same thing but not sure. This info is courtesy of lifelong enthusiast Joe Maurath. He had always said if someone knew the correct capacitor value, they could convert a 1000W GE to a 700W, as genuine 700W fixtures like this one are hard to find!

Thanks guys ! Not including the ones I own , I know of at least 1/2 dozen other 700 w lamps for sale in clear, /C, and /DX.

I read in the 1960 GE lamp catalog that GE considered their 1000w lamps as "dual wattage" recommending using 1000w lamps in "hard to reach" 700w fixtures for longer life http://www.lamptech.co.uk/Documents/Catalogues/GE%20-%20Catalogue%20-%201960%20US.pdf

Collector,Hoarder,Pack-rat! Clear mercury Rules!!

Oh wow that's awesome! So a 1000w lamp can be used in place of a 700w without issue. Interesting. Seems like mercury lamps are fairly tolerable to being under or overdrive compared to other hids.

Interesting, one of the Sylvania lamp bulletins mention running the 1000w lamp at 1500w to boost light output. You get a impressive 85000 initial lumens but lifespan decreases to just a mere 2000 hours though. I think later one they made proper 1500w (metal halide) lamps for that purpose though.

Yeah 700w must be rare now. I never actually seen a 700w lamp or a fixture although I suspect some of the older mercury large cobraheads here might have been 700w at one point.

700w street lights were never used here by the dot or utility company. They're might have been some on private lots but since there were no nema tags in that era I'd never know.

CalTrans actually used GE 700w MV M-1000s. Every single one has been replaced now.
