https://www.worldradiohistory.com/Archive-Catalogs/Graybar/Graybar-1926-1927.pdfHas anyone seen anything that's in here IRL? Especially something like the Brylock sockets on page 248(265 in the pdf)?

I meant desktop systems like Ubuntu or Fedora. On the mobile, if you are concerned, you can deliberately pick up models which are easy to unlock and which are well supported with alternative firmwares like Cyanogen or Lineage.

UVA sensitive phosphors are easy to get from Aliexpress. Most of long afterglow inorganic stuff will work with UVA and for DIY remote phosphor even organic phosphors are OK. Probably you even can pick some at local art stores. Fluorescein and rhodamine solutions look fun with UVA and blue light too! There is also some new bright organic phosphor stuff like pyranine.

On x86 there is no problem as we can install any system for this platform and modify it in any way. On phones this is problematic because most manufacturers require additional steps (some long-lasting) to unlock bootloader to flash custom ROM if available (like LineageOS or other, on some phones even postmarketOS) or to modify stock, or don't allow it at all. On some of them it may have some irreversible consequences (like trip Knox flag on Samsung). Manufacturers may make it even harder (Xiaomi HyperOS if not mistaken) or get rid off in some future update (Samsung since OneUI8).

Aah damnit.
Near zero chance to find them to add to the collection, i guess. Even 'plain' remote phosphor ones are hard to find locally.

By now UV and near UV leds have gotten pretty common so i guess it should be possible to see if production would be economically possible these days - if the efficiency would be acceptable.

It would be fun to experiment with remote phosphor stuff as a hobbyist, but so far i haven't come across vendors of the right phosphors in hobbyist amounts.

A CRI of 70 and 85 isn't that great in today's context. But i know for certain (i have some 2003...2009 LED lamps) the 80 cri common warm white-ish LEDs are absolutely ugly so they could definitely have been better than what was on the consumer market at that point in time.

Either way, i'd like to add somethng like this to my collection of oddball or historically significant LEDs. Same goes for the pre-Nichia era blue LEDs.

On open source distros you are always in control to root out this sh&%, so no problem. Sorry for UK iOS users...

Indeed GE's VioLED is the only one I am aware of which became commercially successful, for a short time.  There was another company in Mexico that briefly produced A-line retrofit incandescent lamps with the same technology of a remote phosphor coated glass bulb around UVA LED emitters around 2012-2015, but they also quickly disappeared, and I forget the name.  UV-pumped technology is considerably better in terms of colour quality and colour stability, but has the penalty of higher cost and lower efficacy.  During the mid-2000s LEDs were developed with a view to achieving much greater performance than is commonplace today, until manufacturers realised that actually selling price and energy efficacy are the only things most consumers care about, and many of the innovations aimed at better quality of light had to be abandoned.

In fact, such short CCFLs were in quite wide use to backlight industrial LCDs circa 1990's. Though, usually driven off classic Royer inverters.
I even still have one in 240x64 size, popular in synthesizers of that era.

GE did 405nm pumped high CRI white LEDs very very long ago under the trademark Vio LED. Probably forgotten now. 2009 story...

Violet and UVA pumped WLEDs would of course lose in efficiency to classic WLEDs considerably due to extra Stokes shift and extra conversion in blue light.

I'm afraid that it applies not only to Discord. I think that introducing so-called "age verification" is global trend and will apply to more services (especially very popular ones) if not done so. There are even mentions of rolling out it at OS/device level. Projects such as GrapheneOS and some distros are against it. In contrast in UK iOS already started to prompt users to "verify their age".
