The star Epsilon Indi features in a novel I'm writing, and I know that a pair of brown dwarfs orbits that star. I want to get the description right, so I was wondering: what exactly does a T-dwarf look like? Does it emit enough radiation at visual wavelengths to have an internal glow? Also, would the cloud-tops be banded like those of gas giants in our solar system, or would the internal heat disrupt that?

Given that a T-Dwarf has a temperature of 1300 to 800?K It would probably look just like an other ordinary gas giant, except in the infrared spectrum. If i remember correctly you need to get up into the 1800-2000k rage before you have any visible light glow.
