12000k xenon car lights

Ballast
Bulb
A halogen spotlight fixture works great as a DIY pendant, bulb fits into the same sockets.
No power source needed, all in all cheaper than a 35W DC Xenon (just bulb and ballast).

So out of curiosity how do they make 10K Xenon? Is it a filter they place on the bulb to filter the spectrum to 10K? Otherwise they would have to add different noble gasses to illuminate a higher spectrum. Any ideas?

I still think a 20K 70W halide would work great on a nano, even a 5.5gal, you could always hang it a little higher and run a small fan for heat if needed. But that's just me I guess. Does anyone have a link to an SPS 5.5gal? Sounds difficult, the lighting would be the easy part.

You have to show me that cause I didn't get that from it.

I'm not sure how got speculation. All did was quote some of what I though were the key parts of the article. And I gave a link to it and it was originally posted by The New Guy (BTW Thanks TNG) and why would you want a blood sample?

Actually my biggest concern from that article is the IR radiation, what filter would you use to deal with that?
