Sylvania Workshop Rapid Start F40T12

Sylvania Workshop Rapid Start F40T12

Click to view full size image

Restore find at the Spartanburg, SC restore. This rapid start T12 seems to be designed for shop lights. This lamp has a relatively short rated life of 12000 hours.

Thank you Andy (Ace100w120v) and Nick (Nicksfans) for identifying its color temperature, CRI, and fabrication date!

It’s a shame the Versailles, KY plant shut down. These Versailles, KY lamps were made in the heart of bourbon country.

I can tell it's from 1995 based on the 5 under the big E, and I believe these lamps are Cool White (4200K) even though they don't say so. Also, 12,000 hours isn't really impressive; most F40T12s are rated for 20,000 or 24,000 hours.

Thank you for the info. Nick I updated everything above. This lamp is about our age, wow! I got two of these so one is all yours next time we meet up!

This is awesome CEB1993, but how would this be identified as High Output? lol

He must have been mixed up as the next picture over is of a HO lamp. But seeing that this lamp here is 3000 Lumens, its still a very good light output. not HO but very good for F40T12, the ones today barely come close, maybe except for the 2900 lumen USA only lamp by GE or the Sylvania Premium ecologic but both of those have barely any mercury to get through the first 5000 hours

Hopefully I can run this up on one of my shop lights to see its true output. After looking over the etch, I'm certain its not high output. It has some minor end blackening, but I'm sure it has some life left.

It should run just fine in your basement lights.

If this is run on actual shoplights with residential ballasts, the lamp will see roughly 25 watts and it wont be outputting anywhere near 3000 lumens but it will otherwise last and work just fine. If used on full power ballasts it will output its full lumen specs but at a little less lifespan

Yep F48T12 HO's are typically 60 watts, with those RDC rubber end caps... (is that correct?)
But yeah 3000 lumens is pretty awesome though. I wonder if these are Halo or Triphosphor? I'm betting Tri lol

I think Workshop F40 is halo CW with a CRI of about 60.

RDC end caps are hard plastic, not rubber, in my experience.

These look like old school halophosphate cool white with a slight hint of purple.
