"Good tip on the clip-on desk lamp. Looks as if it might be a NÄVLINGE from IKEA? It should double as a strobe light, too?"
The one I have has a ballast, so doesn’t strobe. Interestingly, the ceiling fixture I rely on as the reference has LED bulbs in it that when I replaced the incandescents as they blew out do strobe.
"Next time I have a spare 3 hours I will pop into IKEA then try to find my way out again ..."
You can order the lamp online.
