I was recently caught out by a 10W LED nominal 60W lamp I substituted

Was it that the illuminated area was deemed too bright, or the actual
lamp?

Out of curiosity, what lamp was it?

Lighting Ever 10W LED 810Lumen the new one is 830Lumen. Samsung chipset.

It was too bright compared to an aging CFL they had got used to which
IMO was unsafely dim for at least 5 minutes after switching it on.

That lamp is 'daylight white' (6000K) which is a pretty 'hard' light. 'White' (3000 to 3500K) or even 'Warm
white' (2750K) might have been less of a contrast with previous lamp. I have a single 4W LED in the porch
lamp, and when the street lights go out it seems to light up the neighbourhood!
