Where can I read about the proper organization of led lighting?

Question

Do it yourself

I am going to make a large lamp on the ceiling in the living room, and 3w LEDs as a light source. In total, I plan to make 27 LEDs. And I would like to read which LEDs to choose, what drivers to make for them, what to feed, how to cool, etc. I would like some articles or maybe someone will share their experience.

Guys, everything is to your taste (do not forget about shades).
For example, I like the color Cool White almost everywhere in the apartment.
It's brighter and you can see better. In the kitchen, corridor, bathroom and toilet.
They did repairs a year ago, put 6x20w built-in lights on the ceiling in the living room, it is clear that out of habit the same cold white. The wife, as she saw, overlaid with very great criticism. The wallpaper in the room is warm, why did I buy cold lamps ... Now I'm waiting for them to burn out.
Look at the watts - I already overdid it once, my kitchen of 6m2 from the 5th floor shines like the brightest window in the 9th floor. Although there are only 6x11W energy saving.
