Thanks for the responses gents! I'm hoping to secure the fluorescent tubes and ballasts after meeting with Panalux next week, but I'm worried if we'll be able to afford the amount we need on our budget (we're only going to build one wall with the bedroom furniture though so hopefully it wont cost too much). I also bought a strip of LED Light Tape to experiment with and on my DSLR at 400 ISO it seems to be showing up nicely with no flicker ... but more tests are needed.
My biggest concern is definitely what you mentioned, David. If we go with UV lighting for the set I'll need additional UV lighting off frame and it still might not be enough (and also might just look like a bad rave party...). I'm hoping to test it out any way just because I'd like to bring the director a few options.
I'm looking into the 3M material (great suggestion!), which seems cost effective, but I"m not sure it will establish the look we want with the characters. We want them to look like they have been inhabited by light. I'll give it a try though :)
I really appreciate your input and if you think of anything else please let me know! Thanks!
