In. Thanks!
Here's a pic of a Son of Fermentation Chiller I gave away here a few years ago.

Right, as-is it just cools.
Yes, I think it would be easy to add a can light or similar with the current controls. The digital thermostat should be able to control both heating and cooling. I can't imagine the wiring would be difficult.
I used this slightly unfinished Son of Fermentation Chiller for a couple batches and it worked really well. I'm sure it will work even better finished! I have (included) the dowels and molding needed to finish it - easy enough. I have a Chronical with FTSs now, so just don't need this. See...
