Hello there!

I have good news and bad news on this prop:

The good news is that it is perfectly doable on a budget, but the bad news is that you may have to sacrifice on some of the features you want.

Lighted props, larger props, and transparent plastic props (especially shapes like spheres) are notoriously difficult and expensive to make in terms of materials. In a case like this, you will have to get creative.

One of the easier sacrifices to make will be the threaded part. This will open up your options widely in terms of base spheres you can use, each with pros and cons, but should still allow an opening for the lights.

Here are a few ideas for base spheres:
– Clear plastic domes for light covers
– Oversized plastic Christmas ornaments (this would be my choice, I think, as it is closest to what you are looking for). Look for one that says “fillable,” like this one.
– A play ball for children. You will likely have to look around to see if you can find a transparent or semi-transparent version, and create your own opening.
– A pre-made globe lamp (another top contender imo, since the lighting is built in)

You can also attempt making a sphere, though this is less ideal: the striations in the original would make it possible to hide seams in plastic, and the fact that the bomb appears frosted may allow you to hide internal structure like that of a round lantern.

Lighted props like this can get pricey, so look around and get creative, even if it means doing a bit of reimagining of how it works.

I hope that helps! Good luck :]
