| Jun 22, 2021 at 0:18 | comment | added | canadianer | @jamesqf If you have a 1000 lumen flashlight held close enough to a surface such that it illuminates 0.001 square metres (about 3cm x 3 cm), the light intensity on that surface would be 1,000,000 lux. According to Wikipedia, that is about 10 times more intense than “bright sunlight”. | |

| Jun 21, 2021 at 12:49 | comment | added | Alexander | That laser weapon is physically damaging the insects @jakebeal; agreed, a handheld torch won't be powerful enough to do that. However, I was thinking that intense light simply overloads their CNS, it short-circuits and they drop dead! :) | |
| Jun 21, 2021 at 12:31 | comment | added | Alexander | I beg to differ @jakebeal. There're a lot of space between flashlight's emitter and the ceiling, the insects are buzzing and moving around. Moreover, they're not crushed, they look intact (even medium-sized flies, mosquitoes are much smaller but still they dropped dead!) | |
