Default Dummy load for SMPS

I am troubleshooting a SMPS for a projection tv and am not too sure on
what the load should be. The prints only mention voltages, no loads.
The schematics show that a +130vdc line is connected to a
photocoupler, so im assuming this is the line that is used for
feedback regulation, and therefore the one that needs the load. I have
looked all over google for "dummy load" and cant really find a good
site to help me out on this. Any ideas Sam? The sticker on the outside
of the smps says 120v 150w if that helps.
