RMB noted:
There are cars with LED headlights. LEDs can be quite bright. The
tealights in question are comparable to real ones.

CM responds:
Both RLK and RMB have basically responded: Yes, these LEDs give off plenty of (enough) light. In my post I posited this as a fact threshold which RMB  has answered in the affirmative. RMB responded that there are some types of very bright LEDs. RLK responded that even the small LEDs typically used on audio and electronic equipment (power on etc.) give off enough light so you would not trip in a dark room. In my experience perhaps in the immediate vicinity (say 5-6 inches) from the LED there is some illumination but this falls off very rapidly. I would ask if in fact the level of illumination is discussed by the poskim wrt ner Shabbos, whether extremely low and very local (within a few inches) levels of illumination suffice for Oneg Shabbos (and therefore for ner Shabbos)?
