I'll let Jupiter reply but your comment is very nice to read. You are absolutely right, as long as it's safe and works properly that's really what really matters. I can assure you it is indeed safe as they come.Well your chandelier is about the coolest thing I've seen in a while. Can you show a guide on how you threw that one together? It looks ridiculous, but you're the one laughing while everyone else is spending $100 on heatsinks and you are getting far better performance by running water instead.. Is water constantly cycling or do you put a timer on your pump? What have you mounted the COBs on, and how safe is this system as far as leaks go?
