The date the capacitors were made will be stamped into the case in either a WW/YY or YY/WW format, which will give you a close approximation of the fixture's age. Usually it's within a year. L70 may or may not be a date code (either November or December 1970 depending if they drop the letter "I" or not). Or perhaps that's a model number for the ballast.

I haven't got around to pulling out the capacitors, (been meaning to since I got it!) I'll have to do that sooner than later, and as for the "L70" on the ballast, I was wondering the same thing!. I know the original ballast in my ITT 13 has the date stamped right on the ballast so that could be what that means

That's exactly how the ballast looked and was laid out (with 2 caps) in the 400w HPS unistyle I got. I thought it was converted at the time but now I'm wondering if it was OEM.

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

I'm not sure if the offered the unistyle in hps. Could just be because theres no other way to fit the stuff in there.

I looked at a 1971 McGraw Edison Outdoor Lighting brochure and it stated the Unistyles were available in 100-1000w MV, "metal additive" lamps (MH I would presume?) and 400 & 1000 HPS so it could have been OEM

Hmm interesting. I guess it depends what brand the ballast is.

Nice that it has the original gear...the one in mine was toasted and ended up being replaced with an Advance kit.
The date(s) on the PCB capacitors in mine were '67', so would assume 1967.

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

Date code on the capacitors is 70 31 so the "L70" probably is the date , COOL !

Nice! Yeah the capacitor was made 31st week of 1970 so it's safe to say this light was made in 1970! Cool addition! I believe my 100W MV 240V Unistyle was made around 1970. Kind of toward the end for the Unistyles IIRC. They were made alongside the Unidors for awhile but I think they started pushing the Unidors more and more in the 70s.

Thanks, any ideas on how long the Unistyles were made (start year/stop year)?? I'm curious

I'm looking forward to digging my small Unistyle (100/175 watt 120v ) out of the back of the garage soon. I haven't seen it in 5 yrs! lol !

Thanks ! You're Unistyle came from your "roadtrip" cobra-head score right ? and wasn't yours pretty crusty inside? My 100/175 unistyle sat somewhere upside down for a LONG time, It's also rather crusty but it does work !

The Unistyles were made since the early 60s I think. The earliest ones were the split door model for the 400W and the small version had the PC very far off the light in a weird spot.

This is the original small Unistyle:


I personally prefer the 2nd generation small Unistyle, which was introduced sometime in the mid-60s I believe. That Unistyle is the one more people are probably familiar with. From the outside it looks the same except the PC is moved a little closer to the front. Insides have a few changes. The 2nd gen is this one:


Not sure when they discontinued the 2nd generation one, but it was made at least into the early 70s. There was also a Unistyle for 1000W lamps. Looked like a larger Unistyle 400. That one is here:

Yes indeed, it was from that "roadtrip".

I'd love to find a unistyle or unidor 250...I have an original refractor for one, now I just need a fixture.

I've only seen the unistyle-1000 once, and that was back in '85 in the Peoples Republic of California.

I'd love to get my hands on a Unidor 250 as well. Those lights are very unique. All the gear is mounted to the door, which I believe automatically de-energizes when opened. Plus they're just cool looking with their very boxy profile.

They also had a pretty neat looking electrical system. The spec sheet for them shows them having two core and coil ballasts in them. Interestingly the Unidor 400 was offered in 310w HPS...that must have been a rare model.

I believe early models of the B2255 also had a auto de energizing door mounted ballast. Mine is newer and had a top mounted ballast but the door stil had mounts for a ballast.

Until around two years ago, there was a plaza with 5 HPS Unistyle 1000s still in use but it seems like they replaced with LED between 2017 and 2018.

@ Joe: the early M-400A HPS lights had to ballasts as well. I think that was how they did the three coil "mag-reg" ballasts back then. Also interesting is how Cooper still offered the Unidor in Canada in 1985 when that spec sheet and even more interestingly, I saw HALO'S name on the bottom of the last page! 1985 is when Cooper rolled out the OVS and OVM in the US. The OVC later came in 1989.
