Made February 1988 Fairmont, West Virginia. Very neat find, I believe these are somewhat rare. They should put these back into production for the few F90T17 fixtures that may still be in use.

Pride and quality workmanship should lie behind manufacturing, not greed.

You are the only other member here who I have seen to have this tube! I have several of the 84 watt in CW and D and one pair each of the 90 watt T12 in D and CW. Nice find!

And yes I agree with detroittwostroke... Would be a simpler style to put back into production. I actually prefer the 90 watt T12 over the 90 watt T17. They start much easier and are way brighter when cold. The 84 watt ain't bad but is more like comparing a 34 watt T12 to a 40 watt T12.

Wow, never seen one of these before! Yes, this would be the most cost-effective solution to a lamp that can be run in a T17 fixture! Someone should put a bug in the big three's ears...

You're right about these being easier to make than T17s. Heck, they're already pretty close with the F60T12/HO. I still don't think there's enough demand to push a company to make them, but it's a lot more feasible than restarting T17 production. I know Voltarc does a lot of specialty tubes, so perhaps they could be persuaded to whip something up. I'd imagine it would take an order of 1000+ lamps and a good deal of money to convince them, though.

On that note, I wonder how well an F60T12/HO runs on an F90T17 ballast.

I like my lamps thick, my ballasts heavy, and my fixtures tough.

It wouldn't. If I remember right T17 ballasts are chokes, and the arc voltage of the F60T12/HO is too high to run on 120V.

With that being said, I'm surprised to read that these perform better in the cold than T17's, since I assume these have krypton in them to lower the arc voltage to T17 spec.

The big companies aren't going to see profit in production of T17 compatible lamps, but a smaller company (such as Voltarc, Interlectric, or maybe Industrial) would probably manufacture F90T12 lamps, though I'm sure there would be a minimum order. It is an interesting thought!

Nice find toomanybulbs. Very rare to see one in the Philips brand. BTW, TheMaritimeMan, the F90T17 also contains krypton. Only the F100T17 lamp, long obsolete, did not have krypton.

May all the great lighting technologies have their place in history.

Now it would be really crazy if we could get a company to make F100T17s.

Maybe we can contact voltarc or interelectric
By getting all of us to chip in and produce it
To keep our lights going?

No LED gadgets, spins too slowly.  Gotta  love preheat and MV. let the lights keep my meter spinning.

@themaritimeman, the ballast for the 90/100 watt T17 is an autotransformer HPF type. It is 1500 ma, like the VHO T12s. It takes more "kick" to fire a F90T17 than a F60T12/H0.

Nice lamps! But if anyone were to contact a company like Voltarc to custom design a lamp wouldn't custom designing a T17 be better than a T12 or T17s? It's those huge lamps that make the fixtures interesting. And the fixtures are optically designed for the larger lamps.
