Sensitivity aside - light intensity is still inversely proportional to the square of the distance. So effectively - if you want twice the reach of a 500 lumen light - you need four of them ( or one 2,000 lumen light. And if you want three times the reach - you need nine of them - or one 4,500 lumen light.
So don't sweat the small stuff. Nice review!
