Hi moonrabit, you might want to place some stones in the pot so the leaves aren't touching the soil.
I personally don't have any lights setup for my plants but there are quite a few! T5 growlights seems to be popular with indoor succulents, I have run out of room on windows, So lights might be my only option for new plants.
Edit: forgot to add if you do go for lights be sure to get the right spectrum 6500k daylight
