I have seen several product reviews that seem to hint at the UV spectrum could be beneficial to coral. Does anyone have any info or first hand experience?
Thanks!

The short answer is yes, with the caveat being true UV is not possible unless MH's are used. Still, the "UV" spectrum provided by the majority of today's LED's is very beneficial.
that was a good tip...Thanks for the link!See this...

@hart24601 300-400 is accurately defined as Near UV or NUV and true UV light encompasses both UVA and UVB. For practical purposes of recreating lighting available on the natural reef, UVA and UVB will be required for true UV lighting. That is not possible with LED lighting available for reef aquariums.How is true UV not possible if using LEDs? By definition anything under 400nm is UV and at least kessil and orphek have diodes under 400nm.

@hart24601 Here is a good read for you...Do you happen to have a chart showing UV penetration by depth in the ocean? Seems hard to think UVB would make it to corals we commonly keep.
None that I know of. I'm not certain that there would be any meaningful data derived from such a study hence the likely lack of any data readily available.Know of any studies looking at coral response to UV light only (no other spectrum) at the intensity UV is found on an average reef?

I'm not following your query regarding evidence that suggests UV is not important?The sun produces it. It gets to the corals. All true science trusts nature until it is proven to be wrong, not the other way around. IMO, this is why LED tech and some reefers do not go as far as they can since in an industry where proof of anything is nearly non existent, they take pieces and parts of this or that and conclude that some part of the nature are not beneficial. It is pseudoscience.
Then, forget about studies or tests for a minute. What anecdotes and evidence have you seen that suggest that UV in not important? Is there any coincidence that the light source that creates the most UV also performs the best over corals? Nope. Is there any evidence that adding light sources with UV (T5s) to help those that do not have it (LEDs) have been beneficial? For sure.
...so assume that all wavelengths are beneficial from 350 to 850nm, like prior research has shown... which also support nature. If you want work to discredit this, but it will be nearly impossible since only a few publications (think advertising) from some LED manufacturers have ever said otherwise.
