I think I understand what he is asking -
He has a chart of (CCFL) tubes with specified length and diameter and Lumens
output for
that specific tube length and diameter.  What he wants is the relationship
between the
light output in Lumens and the necessary input power in Watts.

I would go back to the manufacturer for that information.

Your question may have been misunderstood. Are you looking for the
thermal power produced by absorption of the light by surrounding
components? Or the power input to the lamp required to produce a light
output of a given number of lumens?
