This is a little bit off the current topic (sorry) but I was in my lfs
a couple of days ago and asked the owner how he liked using the LED
's he had over two of the grow out tanks. They are the dimmable taos that are discussed on here. He said they were doing fine, but when I asked him if he planned on converting everything over to them, he became pretty negative about them, saying they weren't cost effective and that he was losing color on some of the acros he had under them. I wish I had asked him what he had them set at, because my first impression was that maybe he was burning them by turning the lights up to high. The thing he said that prompted me to ask this question though, was that he said they don't have the UV
that corals require to grow, hence the loss of color.
Now, I know that there are plenty of testimonials on here about the growth and color of their corals, and I have loved my fixtures since I got them, and seen noticeable growth, however these are my first lights so I have nothing else to compare them to, and all the corals I have need moderate lighting at best.
Anyways, I wasn't really sure how to question him on what he meant by UV
.. Other than the difference between the ultra violet color and the actual wave length, but even then, I don't know much. I personally have no doubt that these lights can keep anything that I want under them, just would like to know how to convey information to my LFS
. It's a little hard to tell him what to do though seeing as how I am very much still a noob in the hobby :P If anyone has any suggestions or talking points I could use in defense of these lights, I would appreciate it!
