Hi snake_goth,
I had a lot of trouble understanding your post, so please correct me if I am wrong...
You are getting a carpet python (I guessed that from your signature), and you want to make a lamp guard for its future adult cage?
I have attached a picture of a simple lamp guard. Just buy hardware cloth from any home improvement store. Make sure the hardware cloth is not coated with plastic, as the plastic will burn.
Other designs would be to just make it into a box shape and screw it onto the cage ceiling. If you do a search, there are several posts regarding this on ssnakess.
Hope this helps.
Cheerio!
