I recently built a wood terrarium with dimensions approximately 3 ft x 2 ft x 2 ft and am looking for advice on installation of a CHE. I understand I need to use a porcelain base and install a guard around the bulb. This is what I need assistance with:

1. Should I use a specific type of wire to protect against the heat?
2. Do you recommend a pendant style base or full sized base like you might find used for lights in an unfinished basement?
3. Can the base be at the top of the enclosure or should it suspend below to prevent overheating the wood?
