How Far Can A Candle Be Seen In Total Darkness. In summary, the maximum distance a light source of a known lumen output can be seen in complete darkness is about 0.42 miles, which is. A candle would have a comparable brightness at a distance of 2.6 km (1.6 miles). Such claims might come from 1940s work out of columbia university that looked at how the eye responds to flashes of light in a dark room. Now a pair of physicists have carried out an experiment to find out. How far can the human eye see a candle flame? Answers on the web vary from a few thousand meters to 48 kilometers. You can use geometry to calculate the number of photons. Various claims in television commercials and on the web suggest that the human eye can detect a candle flame 3.5 to 30 miles away. The former are 251.2 times brighter than the latter, which allowed the scientists to calculate how far a candle would need to be in. This is the effective distance limit at which the human eye can discern a candle. Various sources on the internet suggest that a candle is visible to the unaided eye at distances varying from 3.6 to 30 miles. A candle flame situated at 10 miles (16093.5 m) would have an apparent brightness of v 5 log (16093.5/162.5) ~ = 9.98 mag.
