I wonder if the asymmetrical drive to the transformer is giving an asymmetrical enough waveform on the output side to drive the lamp in something like DC, so we can see the positive column, Crooke's dark space, etc. That would be cool.</p>

The UV lights they use add special external filters to remove the visible purple/blue light coming from the bulbs and pass only the UV, but unfortunately the short wave UV filters are a bit expensive.<p><a href="https://en.wikipedia.org/wiki/Fluorescence#/media/File:Fluorescent_minerals_hg.jpg" rel="nofollow">Click to view an interesting Wikipedia Fluorescent Mineral Photo</a></p><p>They also make handheld and UV display lights for fluorescent mineral collectors with all three UV bulbs (A,B,&C) with the UV filters mounted inside the light case.</p></p>

It really doesn't look great to me either (in fact there are quite a few of us who would like to change it). The fact is, the image carousel does look better than a bunch of 600sqpx images in line... but I agree, the motion is distracting.<p>Within our authoring tool, we use a markup alias to place the image carousels (which are interpreted on page load) so unfortunately, as publishers we can't adjust the parameters of the carousels unless we want to re-implement them from scratch.</p><p>It takes time to change things but your grievance has been registered.</p></p>

I've built an eprom eraser using a longer tube made from an under the shelf type fixture that used an old school style neon bulb starter. Yeah, I guess eproms are a bit retro these days, but I still have a ton of them.</p>

I would think you'd want some sort of warning or security device on the USB-C bulb, lest a coworker "borrow" the device and accidentally burn themselves. Of course, that's probably what happens when you borrow much of anything from Nick's desk...</p>
