Just like in the thread title: do/did CFLs with halophosphate phosphor exist?
So far, all the CFLs i have appear to be conventional triphosphor ones. Even my oldest ones (those Philips SL 'jam jars' with magnetic ballast) are triphosphor.

Yes I had a couple of such lamps. In the classic 3U form. Were sourced from one of the the cheapest local importer. Nothing really good. The color was kinda pinkish with bad apparent CRI, light output was low. I used one of them briefly in my bathroom. Halophosphate is a poor choice for CFLs as energy loading is high, so phosphor life is expected to be short. I have confirmed these were really halophosphate coated by looking at the spectrum.

Ah, interesting, thanks!
Stupid me left my little battery operated tesla coil at work - i'm gonna browse the thrift store's bins of old lamps to see if i can track one down. I can't (aren't allowed to) test stuff in the store on mains, but the tesla coil will make them glow so i can look at the spectrum.

Filament LEDs. Both a blessing and a curse.

I currently have two halophosphate CFLs in my collection. Nothing special either; a Westinghouse from 2002 and a no-name Chinese import.

I believe I have a halophosphate WW CFL. it has a yellowish, low-CRI look to it. It is 44 watts, and was made by TCP and is marked "Good Lamp".

Neat. I like the weird, bargain basement stuff out of curiosity. Definitely will rig something up so i can distinguish between the phosphor types without needing mains. I bought a brand new 8w fluorescent in color 33/640 which was supposed to be halophosphate cool white - brand new from Osram, stamped 640, datasheet shows the proper spectrogram. I get home - very obviously a triphosphor coating, despite the etching declaring the low CRI! Oh well. It doesn't surprise me considering high CRI 840 tubes are more common, why keep making the 640 ones... And thanks for the welcomes

I Remember about some no name cheap cfl in late 2005 which were 5000°K and glowed for some minutes After shut down. As far as i can Remember, they were horrible in color rendering (really, they were much worse than you think and all lasted only some hundred hours), so may i suppose they were halophosphate?

I've had good quality Philips and Osram CFLs with the afterglow too. I doubt that's the qualifier for figuring out if it's halophosphate or not.

I wouldn't be surprised if some cheap no name self ballasted CFLs were halophosphate or if some cheap PL style CFLs were also halophosphate. I think even the 4ft T8 lamps, which were typically triphosphor, had a brief period where halophosphate ones were made as the entry level lamp when the costs of triphosphors went up.

HID, LPS, and preheat fluorescents forever!!!!!!

Here is a North American market Yorkville preheat CFL lamp that is halophosphate cool white: https://www.lighting-gallery.net/gallery/displayimage.php?album=search&cat=0&pos=4&pid=190520In addition, there were also the FUL lamps, which are non-integrated CFL lamps requiring external ballasts, which are often halophosphate and were popular in North America and Japan. However, most FUL lamps produced today are BL lamps commonly used in insect killer fixtures.

I've owned a Halophosphate CFL as well, when I was a little kid. I forget the wattage, but I'm pretty sure I remembered it being 15 watts. It was a screw-in self ballasted CFL... the triple U-tube style. It was one of those cheap CFL's from a store that didn't last long in St.louis Missouri, called "Factory 2-U." The manufacture brand for the CFL was "Factory 2-U" as well, so it wasn't a no name type of situation there. I do remember the CFL print said that it was made in China, and the plastic base seemed REALLY cheaply made. Instant Start electronic ballasted. It was very obvious that it was not only WW Halophosphate, but also very much under-driven. Most colors seemed dull with it, and I was at that age where I was able to distinguish the differences between Halo and Tri, so I was immediately able to determine it was Halo. I was able to confirm it simply by switching off and on the lamp while flipping my eyes up and down. While doing this, I saw the immediate afterglow was orange/yellow. In *most* cases, the immediate afterglow will appear orange/yellow if the phosphor is Halo. That was the only Halophosphate CFL I've ever seen outside of Lighting Gallery. I can't help but wonder if there's such thing as PL-L lamps that are Halo. I'm also interested to know where I can find that CFL that Silverliner owns.

I also have some FUL lamps that are triphosphor despite being halophosphate according to the etch.

So far, i've seen no PL lamps that aren't either 827 or 840. But in a week, i'll be able to grab my little tesla coil and test the bins of bulbs at the thrift shops. They typically don't want you to screw the bulbs into a random lamp of theirs and then go start testing everything.
I did do a couple but since the bins contain a couple dozen, it'll take a while. So far no luck. Luxury problems - plenty of better 827 ones to be had.
