Sim Kar Louvered Fluorescent Lights Detail

Sim Kar Louvered Fluorescent Lights Detail

Here are additional pictures of the four foot section I rescued. The side panels drop in to hooks on the end plates and are held in by gravity. The louvers and ballast cover snap over steel "nubs" on each end. Decorative end plates are bolted on to the ends of each row.

This has an Advance REL-2P32-RH-TP instant start T8 ballast. It seems to be a good ballast. It has no EOL protection so it has a high ballast entertainment factor! I enjoyed a light show with an EOL lamp. Manufactured 46th week of '92. Factory code 974N2BB3.

I received about 60 lamps with these fixtures. I think the electricians were happy to see me take all the lamps so they didn't have to pay for disposal! 42 lamps work. Most are Sylvania FO32/741/ECO. I also found a pair of 5000K lamps (one is pictured here). The other lamp pictured here (4100K Sylvania) is the oldest-looking lamp in the bunch. Can anyone date it? Code is A828 with the A underlined. The date of this lamp could well be the approximate date these fixtures were converted.

I don't have a use for these lights at the moment so I will leave them set up for T8 right now. Depending on where I use them, I may convert them back to T12 rapid start. These also have knockouts for starter sockets so I could go preheat, but since these were rapid start originally, I will save my preheat ballasts for other projects. The knockouts are right next to the ballast on the top (ceiling side) of the light. Therefore these could only be used with starters if the lights are suspended or stem mounted.

Edited to revise ballast date code and newly-discovered starter knockouts.

For the Advance ballast you posted is probably a 1997 vintage.

Pretty, please no more Chinese failure.

I decided to search Philips' Web site and see if they had a document that explained their date codes. They do! Link. In fact, I missed the two most important numbers in the code: 46 92. They were stamped above the factory code and very close to the edge, so I overlooked them. This ballast was manufactured the 46th week of 1992. Good guess rjluna2, but I gave you incomplete information!

Congrats on being able to rescue these cool vintage fixtures. I used to see louvered fixtures quite frequently as a kid but lately they seem to be disappearing.

I suppose 1992 is very good for an electronic ballast over here it is very very rare you see any ballasts from the early 90s still working! Most have died! Hense the reason i dislike them so much. Swtich start (pre-heat) No problem i know of places that date back to the early 60s never had a replacment ballast!

Voted to leave the EU and proud! 👉🏻🇪🇺🇬🇧

These seem to be good quality ballasts. However, I did see one new replacement ballast, so they aren't perfect.

David, I have noticed the same thing. I see very few louvered fixtures. Our post office still has some very nice louvers and there are still some at the school where I found these (I hope, anyways!). Many that existed even ten years ago are gone now.

I actually like some of the new louvered fixtures. A local Meijer's store recently installed many new louvered lights. I was surprised since so many places are getting rid of them!

Ballast is made in the USA. Probably explains why it has lasted so long. Every modern electronic ballast I see now is made in China.

Thanks nodgen

Sorry, I didn't read the whole caption carefully about the ballast.

I have a similar ballast and several of the older Octron Sylvania lamps like that. Nice find on the fixture too!

Preheat Fluorescents forever!
I love diesel engines, rural/farm life and vintage lighting!
