Most important consideration is what kind of front lights you’re using. We use a reflector such as you’ve shown with a 400w photo-flood for illuminating large areas. It produces a strong white light but clearly it would be overkill for your application. Your reflector will throw light all over the room and unless you’re using flags it will be very difficult to control.
I have a small fluorescent work light that we often use for back light. It’s only 60w as I recall, but it’s rated at 3200K and plays nicely with our NRG front lights.
The bottom line is this: make certain the “color” of all your lights is the same: no low-wattage yellows with higher wattage blue/whites.
