The purpose of the bulb is mostly just to get air moving through the box. Try using a fan instead to move air through the box.

Thanks for sharing this! I need your advice though, I have recently moved to Europe from SA temporarily and I want to make biltong in my biltong box. The problem is, here in Europe they only really sell LED bulbs – which don’t get very hot! What size LED should I use? How do I know how much heat I will get?

I am not familiar with the process of making jerky. The biltong box merely dries the meat, so you could use it for that part, but I believe jerky also uses some type of smoking process.

Hello
The appropriate temperature inside the box ?

Kelly, you don’t need a large box if you’re only making a few pieces of biltong at a time. At it’s most basic, all you need is some sort of container where you can hang your biltong and move air through to dry the meat. You might not even need a light, especially if you live in a drier climate. I only use a cardboard box with an open top, and a small fan blowing air in at the bottom. If you hold your hand above the top opening of the box and can feel slight airflow when the fan pushes in air at the bottom, you’re good.
