Personally I would use DBT with 60W bulb. 100W bulb may not lit up bright enough.
I think you can test DBT with any cheap electrical device. Place it on concrete floor and see there's no flammable material nearby for example to be absolutely sure. Also you can check the wiring with DMM continuity mode.
It's good to replace output pair for channel. Not all 4, if one channel works fine.
I think majority here are to learn
