Personally, I always suggest around a 200 lumen max light for In Home Offense use.
Here is why: (I have posted this several times) If you do a few tests you will understand my logic. If you have a 200 lumen light and something like a 900+ lumen light, go to sleep set you alarm for say 2:30 am, when it goes off, instantly jump up and grab your light and flip it on and search your abode. Do this two nights with both lights.
You will likely find something around 200 lumen is the perfect balance between bright and not too blinding (blinding you), plus I think you don't want to over illuminate the scene. A light that is too bright could give off your position! If you have a armed intruder, the last thing I feel you want to do is have too much light that could celling bounce or wall bounce and show you! You also wouldn't want them to have visual clues of the room or home layout. Therefore, I prefer something like the Surefire TIR lens.
IMHO: The perfect home offense rig is a Remington 870 Pump with the older 200 Lumen Surefire Forend weapon light. The new series is 600 lumen. To me that has its applications, however in a average home I think that 600 lumens may be pushing it. But to each is own! Now, if you think you will be operating outside your home, or have a large area to cover, then 600 lumens may be perfect for your application?
It is worth mentioning, the cycling of a pump action cross all language barriers because it is multi lingual.
Opinions & situations may vary greatly on this topic, that is why I suggest YOU do a test to see what works best for YOU and your application
