1400 Watt of LEDs is the kind of lighting you'll find atop a tall pole in a sports stadium. That's ~200,000 lumen, or about 10x as much as you'd need to light a large room
really brightly. If you put that next to a skylight, it would make the sun look dim. It's certainly not impossible, but that's a lot for a single point light source.
What are your rooms like? Do you live in a castle?
