Compared to my watch whose dial illuminates because of phosphorescence is the Traser Trigalight much brighter and mainly it lit with the same brightness (for the coming years!), While the dial of my clock is significantly weaker after a few minutes. The Trigalight trailer I attached to my key, so I can now find it even in the darkest night. ;) Those who expect the luminosity of a flashlight can access safely here.
