For my layout photography, I use professional 3200K fresnel lights. Studio and location "hot" lights, as they are called, are 3200K. These lights are typically used in stage lighting for theatrical productions and interior movie sets. Additionally, I now use 3200K LED panel lights. LED lights are rapidly replacing "hot" lights for studio use. They're light and they don't get hot. They also come in bi-color, variable from 3200 to 5600.
However, you don't need to use professional 3200K lights for your layout photography. As I've previously said, the key is using a consistent color temperature whether it be 3000 K, 4100 K (most flourescent shop lights), or 5000K. You may prefer warm (3000K) or cool (5000K) but your camera doesn't care, as long as they're all the same color temperature.
