For a base, I used Dubé airflite glow in the dark clubs*. I cut about 2cm off the top to allow access to the inner cavity to store the battery pack (2 AAs). Then I wrapped a 3m piece of white EL wire (starting at the center so as to have it lay out evenly), hot gluing the wire in place every 1/2 wrap or so. After the wire was glued in place, I took a 1-inch wide roll of saran wrap and wrapped it tightly to help secure the wire. I used a narrower piece so it could go on more wrinkly free.

Once the wire was secured to the club, I put the battery pack in the cavity sandwiched between 2 pieces of foam. Another piece of foam was put in to essentially cap the cavity, to keep the battery pack from flying out.

All this weight made the clubs quite end heavy. To combat that, I wrapped some lead wire at the knob end of the club and secured it with black athletic tape. I continued the black tape wrap all the way up the handle for looks. In retrospect, having black handles on juggling clubs you plan to juggle in the dark was a bit of an oversight, but it does make the clubs look cool.

In the end, the weight and counterweighting made for some dang heavy clubs. And the 1 of the 2 brands of battery packs I used flickers off if dropped (or caught abruptly). But all that said, they look pretty freaking awesome. It was a great experiment.
