Pa to sam te i pitao.
Ako je to "tiho" osvetjenje trajno, odnosno danima sa sijalicama na stolu i bez kontakta sa bilo čim, onda to ne može bez izvora jonizacionih zračenja.

Ako je privremeno, tj. traje neko vreme pa utihne, onda je posledica optičkog pumpanja fosforescentnih materijala koji nisu radioaktivni. Oko toga je nekoliko kolega napisalo iznad.

Ako trajno slabašno svetle samo kad su ušrafljene u grlo, pošto su to veoma mali potrošači pri niskom nivou svetla, onda mogu biti napajane do tog nivoa čistim kapacitaivnim prenosom između provodnika u zidu (kao da imaju serijki kondenzator reda nekoliko stotina pF).
