You put your finger inside one of the grooves of your PowerGroove.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

Wow, you found out quick! I was trying to make a powergroove on a dead t12 and one groove got too hot and it got sucked in like a balloon and practically sealed off the inside of the tube, but the arc found a narrow space to go trough.

The tube i s now RIP, I documented it lit and it shattered 2 mins later. Shame. Hope I can find myself a real powergroove someday

New lighting technologies is a pity fest everywhere you look. From LEDs that last only for two months, to a never-ending global starvation of t8 fluorescent tubes.

Still I admire the fact that you made a homemade PG tube

I will give LEDisease a taste of my shoe

Thanks! Try it yourself.. so easy. Find a dead t12 tube that you are not keep on keeping and go to your stove, light the burner on the lowest, take off the cast iron black plate so the real stiff flame would show, take a tube and heat one spot until a groove forms. rinse and repeat. after immediately document it lit and after two hours it will shatter on it's own. It's a temporary thing you know.. After the grooves are done you can light it on IS ballast and enjoy it

You have to anneal the glass to remove stresses and strengthen it, thats why it shatters. Also a blow torch seems to work well for members that try this

I could try to anneal it with a 1 foot tube, because it can fit in my electrical baking oven. I could leave it there at 300'C for a night or two and have it anneal itself. But then the elctricity bill... idk man, maybe someday I could try it.

I think a few hours or less would be enough, I'd advise against leaving ovens on unattended, especially for days at a time. Pretty cool experiment you've done though, i'll leave it 5 stars

I admit, this is a cool experiment, but I definitely would NOT recommend everyone try this. Not just because of high voltage, but also because of the gasses within the lamp. Blow torch + gasses inside of an arc tube... I'm pretty sure this is a dangerous experiment. Awesome, but dangerous.

Interests
1. Motorcycles, Women, and Lighting (especially fluorescent)
2. Weighting/staying extremely athletic
3. Severe Thunderstorms of all kinds
4. Food and drinks. So gimme them bbq ribs
Yep
Lighting has been a passion of mine since I was born. I consider everyone on LG to be a friend

You live, you learn. You experiment, you discover something unusual. You do nothing - you merge into a turtle shell and leave curiosity behind.
I also do not recommend try this to any under aged kids out there, but if you really know what you're doing, and you know the risks you are taking, such as follows:
1. the tube might implode in your hands, sending microscopic glass of shards in very rugged shapes in the deep layers of your skin, that will probably make you experience pain far grater than million volts cooking your hands to perfection,
2. Hot mercury vapor and other hot gases from shattered tube might burn your hands and/or face making you very ill and at the same time giving the risk of infection from burned skin.
3. toxic airborne phosphor particles along with airborne microscopic shards of glass might get into your lungs causing devastating consequences, excruciating pain and very long recovery and or maybe death.
4. And if you manage to perform the operation "homemade powergroove" successfully, don't expect the modified glass to stay that way. After about two hours it will implode on its own so keep in mind that you should be always cautious when handling the tube, because you can get a very nasty surprises, especially if you are handling the tube lit on IS ballast that deals with tens of thousands of volts to kick start and maintain the arc, because the tube can shatter while being lit and you can give yourself a deadly and I am not joking, a truly murderous-to-self shock, that will endup in your death 100%.

So are there anymore kids who would like to try this yourself? If yes, I admire your brass balls, but all you do is at your won risk, I will not be responsible for your won undoing just because you saw a dump guy on some site who did this to a poisonous gas filled glass bomb.

-I dont speak English very well. Compact Fluorescent (PL)

For what specific use are these lamps?

These PowerGroove lamps were designed to be brighter and to light up a bigger area using the same wattage lamp. The dimples inside the tube curved the arc stream wuitch made it be closer to the phosphor coating, much closer than compared with regular tube witch allows the arc stream just sit right in the middle. When the arc is closer to the phosphor coating, the phosphor coating illuminates with higher brightness and this it creates more light using the same wattage, aka F96T17 PG lamp is much more brighter than normal F96T17. Also, one thing to note: PG lamps were made in only T17 envelope as far as everyone is concerned. And the PowerTwist model was produced in T8,T10 and T12, but never in T17 as far as I know.

PS.
The tube in the picture is not real PowerGroove, because they don't exist in Lithuania. I made it by myself wia heating one point of the glass tube on the open gas flame until glass softened to be driven inside the tube wia the vacuum. I have made countless tubes just for a momentary satisfiement, because the stresses in glass that have been introduced from the flame and bending causes these modified tubes to crack and loose vacuum in the matter of hours, and sometimes even minutes. This particular tube, and the whole concept of the image was that this one dimple got driven so far into the tube it touched the other side and left a very narrow slip for the arc to go trough. So half of my long thumb was able to get inside the tube. When the tube hsattered, thius one dimple had it's glass so thin that it was almost like plastic. It was so thin it was flexing like plastic and didn't broke. I wanted to make a video of it how I made ultra thin glass in my home, but I forgot to do that and I cleaned the shards and threw them away, only realizing I didn't film it afterwards.

I've never seen PowerGrooves or T17 tubes in Finland, but Finnish Itsu had T17 fixture: https://issuu.com/cyrilbarrow/docs/itsu__1965/8

Don't care my errors in Writing and my bad English.
LED fad off!
Fluorescent and low pressure sodium are best!

I have never seen a t17 nor a power grove here in Lithuania too, but I know for a fact that they existed here sometime ago when Lithuania was importing things from usa. I might get my hands on some someday.

The Powergrooves found in Finnish 1994 GE catalog. Although its headline says, that they are intented for special applications and imported devices. I never see in use too.
