Is it possible to create different intensity light zones in 5 gal tank, or the only solution is to make separate setups?

As many of us do, I am getting corals that are interesting to me, and now faced a situation when the light in the tank is too high for low light species. Is there a way to create different light zones in 10" tall tank? What I could think of:

• Placing them under overhang under LED light makes too much shade, not enough light.
• Using PAR38 bulbs, with more intensity at the center, is a possibility, but still either too little for SPS or too much for low light zoas.
• Flat lights with even light distribution (Nicrew Saltwater, Lifegard Power2) worked well until now, but have to keep not optimal for both groups intensity, a little too low for SPS and a bit too high for low light species.

Is separating them in own tanks with optimized for each group lighting the only viable solution?

Place the corals that have lower light requirements... lower in the tank. Or reduce the overall lighting by 10-15%.
