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

About that Westinghouse Lifeguard disease, I think I've caught it. Thanks Eric!

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".

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=190520 In 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.

Quote from: Laurens on December 29, 2023, 11:11:56 AM 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 also have some FUL lamps that are triphosphor despite being halophosphate according to the etch.
