They have end blackening apparently.... Not sure how bad that is. Very bright lamps!

Thanks

Upgraded the photograph.


The ones with glass inside are 6 footers and I don't think I can safely run those on this ballast...

I will leave the tubes running for a few hours because they've been sitting around for decades...


The end blackening is going away a bit.... I think some of it was mercury...

FYI , some F96 ballasts can also safely run F72's , what's the label say ?

Be careful- Running them long time could put them in shock and loose vacuum,

Don’t let the blackening fool You these bad boys are tough,

The only thing You have to worry about is them losing vacuum due to stressing the glass - be careful, I would not recommend running these to long 😎! Nervous!

Other then that -Looks Great πŸ‘!

I know of a place to get more if these loose vacuume.... Although I'd rather not bike tubes from 20 miles away home...


I think I will continue running them... Simply due to the fact that these lamps were meant to be put in actual service anyway... If they can run for a few hours without loosing vacuum i will know I can trust them to last. Not that I'd throw these in service... At least not yet.. Maybe one day when I get a bunch more..

Very Cool!

Colored Fluorescent's such as F40T12 Red or  Green or Blue are awesome...

Very nice! I see you're running them in a HO fixture. I do the same thing with my 4' Powergrooves and in fact I have a single lamp F48T12HO strip light that I have dedicated to running my Powergroove lamps. I personally like running them on reduced power since they're already bright enough on the lower power for home/display use and I feel the lower power stresses the lamps less and reduces the risk of them loosing vacuum.

I have a proper F48 Powergroove ballast but I've never ran my Powergroove lamps with it.

Yeah I would like to see these on VHO but I'd never permanently run them on VHO... HO is enough..

Also they've survived running for 8 hours straight so I assume these tubes are safe despite how much I banged them around on the ride home...

Also the ballast in this is capable of running F72's but I don't feel like dismantling the fixture just to test em so I'll wait to find a proper fixture for the F72 power grooves.

Purely incredible seeing these lit! I love the fully grooved ones they are the best ones ge ever made. Pure white color too! They probably be fine in a ho ballast but i perfer a vho ballast.

T12/ t17 there's a reason they made heavy magnetic ballasts

If I ever get a VHO I will definitely be lighting them up on it.... I'm thinking of dual installing both a VHO and a HO ballast inside my HO fixture with a selector switch so I can flip between different brightness. I'd just put the switch in on of the existing knockout holes and I'd hide whatever small amount of circuitry needed inside the massive fixture.
