Default fermentation fridge heat source?

I've set up a fridge for fermenting. It's controlled by a dual ranco unit. The cooling is a no brainer but I'm looking for some advice on the heating.

Right now I have a light bulb in there and it's working fine. But I wonder about the effect the bright light will have on the fermenter. I protected the fermenter with a dark tee shirt but is this enough? Would I be better off with something like a heating pad? What do you use? What do you recommend?

Thanks!

Incandescent bulbs put out very little ultra-violet. I use an old hard disk & enclosure. It produces about 25 watts of heat and has a built-in fan.

Terrarium heater. UL listed for wet locations. Capable of heating a 16 cubic foot freezer to 90 within 24 hours.

What is an old hard disk? Like a computer hard drive? I did not know those made much heat. How do you power it?

Also, with the temp high and the fridge door closed, I could see things getting kinda funky in there. Any tips on keeping things fresh? Do you have any problems with mold?

I'm still working on my fridge set-up, and I was wondering about this as well...

I've been using one of this in my chamber. Very happy with it.

I used to buy these when I had chameleons, I don't remember them being expensive, but they sure did heat up nicely!

I use a little space heater with built-in thermostat to warm my chest freezer during the winter.

I use a heating pad. When I have just one thing fermenting, I'll wrap the heating pad around the carboy. If I'm doing two at a time, I'll just leave it in the fridge. Seems to work great.
