The "forbidden"Pb 
3P
3P1 line at 1278.9 nm is measured by diode laser absorption in a resistively heated hot-pipe filled with a lead vapour and argon as buffer gas. The
measurements performed at a temperature of 1170 K and a lead number density of 
cm-3 yield the oscillator strength 
which corresponds to a radiative transition probability 
s-1. Within the error bars, the result is in agreement with theoretical data published by different authors.
