Subject: X-ray tubes: photon flux

i am working with plasma based x-ray sources and am used to terms like
photons / pulse , Spectral brillance , Emitted power per bandwidth and solid angel
or conversion efficiency (electrical in , radiation out)

I wonder how my source numbers like 30 mW/ sr or 2 10^15 photons per second per sr
benschmark with conventional x-ray tubes.

I didn't find equivalent numbers for x-ray tubes.
Suppliers usually just mention the electrical power e.g. 400 W.

Can anyone out there give me some numbers of x-ray tubes emission
e.g. photons/s/ solid angle or rad/area in distance x or x-ray power/ Watt/ sr etc.
or conversion efficiencies for x-ray tubes.
(best for "softer x-rays lets say 1 - 5 keV)
