Click to view full size image

These are 2 GE F24T12 slimline lamps, used just once for a test. The one that is black at the end has a broken cathode that was broken when I got it.

Daylight, 2' slimline, AND for export only? I had no idea these were affected by energy regulations.

I really want an F24T12 or F18T12 (does that even exist?) fixture.

Any machine is a smoke machine if you operate it wrong enough.

I know F18T12/HO exists because don93s converted a desklamp to run the F18T12/HO lamps. I don't know if it exists in slimline though.

These are now rare. I have one in SP41.

@Fluorescent05: Do you have Fa8 lampholders for these lamps?

Good quality things are awesome. Cheaply made things are not.

@fluorescent lover 40, I do have the holders for these lamps and the proper magnetic ballast.

I don't understand how that lamp could have blackened faster when slimline lamps have shunted electrodes anyway and never get preheated. I assumed that as long as the filament is attached to at least one support it should work since its shunted

This one's filament was completely busted off of both supports in shipping. It was just rolling around inside the tube.

Yes, it will, but it will have an EOL-like performance.

Ah I see, these lamps are still available in my area. My go to supplier still has them in stock. Even the 36in and even a 42 inch 35 watt one.

I still have both of these, even the EOL one. Maybe I should get another one or invest in some F48T12 slimlines.

They are so expensive and my parents don't like my lights as it is. I'll probably do the first, but maybe, later on, the second.
