What light should I use for this video lighting hack? (ASAP)

Hi everyone! I have saw this very interesting video a few days ago, where a youtuber called "DSLR Video Shooter" talked about this unique and relatively simple cinematic effect where he used acrylic/glass mirrors. So I've hopped to the nearest "home depot" store and bought the acrylic mirrors.

The big issue is that my gear setup is quite different than his, I am using only one Godox SL100D light as my key light, and I don't have another pro video light, especially with fresnel and barndoors (the one used in the video). Since most of the things in filmmaking can be done DIY, what kind of lights source should I use, preferably on budget?

I would really like to make this effect for my product shoots, so any advice would be appreciated :D
