ATM I am still deciding where to keep them, it's either a balcony(I live in a hot country) or a room with out much light. Also I have bred birds before and raised them too, it's just my first time to come across "UV Lighting".UV Lighting is the less of your needed knowledge needs at this point. But, since you asked; There has been numerous Threads on this subject. Based on that, consider using the Search button found in the header above.
In addition, since you are going to bury these poor Parrots in some dark place. Any lighting should be great lighting. Really, no natural lighting? Hmmmm. Anyway, create a grid based on three meter square and place an light fixture at each corner, starting in the corner of this 'place.' Since, the walls, ceiling, and floor will likely not be painted, you will likely need to use 100 watt LED 'Day Light' bulbs.
Example: a 6 meter square room would have nine light fixture.

I just want to add that any natural light coming in from a window is no different than the light coming from a bulb, as windows are specifically designed to prevent a minimum of 97% of any UVA/B lighting from penetrating. I only mention this as natural UVA/B rays are important with helping with certain vitamin production, but it cannot be achieved through windows. It does, however, help with mental health which is just as important.
That being said, I live in a basement suite with little to no natural sunlight due to the window being high on the wall and very small in size. My birds have never had a problem health wise. I do take them out in my vehicle when it's not too cold as car side windows do not block UVA/B rays.
