Great question! I recall Cubic telling me they thought the Orbit’s lights would be strong enough for photosynthetic jellies but I’m not super confident in that. I wish I had one, I’d check the PAR level for you. I will attach a link for an inexpensive Amazon light we’ve used successfully.
A UV light won’t affect them negatively in any way. In fact, I like using them when possible. They really help keep the water clear and prevent free floating algae or bacterial blooms.
Here’s that light: https://www.amazon.com/dp/B075H8QN4R/ref=cm_sw_r_cp_api_i_W97ZC2WAQBW9GDNVHB4G
Just make sure you select the saltwater version.
