A sturdy tripod is one of the most important additions. For close-up work you’ll often stop down to a small aperture (around f/16 or smaller) to get enough depth of field, which means shutter speeds can get long. On a tripod, long exposures are fine for still subjects.

For lighting, a simple diffused setup is more important than a powerful LED panel. A homemade light box works very well for small product shots: a box with white diffusion material and lights placed on the left, right, and top will soften shadows and give a clean, consistent look. That will usually work better than placing items directly on a white table.

Clamp lamps or similar fixed lights can be a practical choice, especially if you want repeatable results. A white background inside the light box will help create the clean stock-photo look.

Light flicker/frequency is generally less of a concern for still life if you’re using a tripod and longer exposures, since you’re not trying to freeze motion. Focus more on even, diffused light and a stable setup.
