alant Posted September 22, 2007 Report Share Posted September 22, 2007 Hi dear all, may I know for an estimate how long does those lume glow in darkness if for example the dial has been charged for more than 15 minutes or even longer under lights? Thanks. Quote Link to comment Share on other sites More sharing options...
sssurfer Posted September 22, 2007 Report Share Posted September 22, 2007 From this data one gets the pessimistic conclusion that after 8 hours the glow of SL is 1/100 that at time 0. Don't worry, as those values are measured with a photometer while the human visual system works differently and it compensates for low-light conditions. To have a rough estimate about the 'human translation' of those data, just imagine that the scale on the Y axis is linear instead of logarithmic.
