Blacklight Posters - amazon or ebay. Ebay you can find unique 23/35 posters used or even brand new. It amazes me there isn't more companies printing with UV Inks.

Any non UV black light art - Callie Fink (the best psychedelic artist I have ever seen), her work is like looking at a heroic dose. But you can get some of her work on fractality. https://fraktality.com/ This art under RGB color changing lights is a trip. My next trip cave purchase!

RGB Light strip - https://www.amazon.com/gp/product/B07L5C8GQM/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1 But other cheaper RGB strips with pulsing/fading color lighting effects will do fine. Just make sure you get the correct 3 pin connectors and an extra ac charger.

Black Light - https://www.amazon.com/gp/product/B078SQZRYG/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1 These are bright as hell but kind of a waste as they lose their brightness significantly if connected together with a second roll even when using a more powerful ac adapter. Also they were a nightmare to keep a connection when cutting within a single roll even when using the correct connectors. But 60 watts is much brighter than 24.
