Probably similar to a 4800 except that the 4800 has a resistor power cord instead of a ballast tube.

Did you notice that Sentinel offered a resistive power cord extension to operate the model 4800 on 220VAC? That would make the total cord power dissipation about 70 watts. Not a good idea to bundle that cord up and hide it behind the sofa.
