Minimum usable illumination -- ideas?

Older I get, the more I need 10 actual lumens to be my firefly mode.

Sure depends on the level of background light too!

Interesting, I find indoors wall bounce makes lights look brighter, so lower levels work well. We're all different though . . .

Bounce (indirect illumination) requires more lumens than direct illumination.
