What to expect when Switching LED Fixtures

[aarbutina]

Good Morning Lighting Gurus, this past weekend I swapped out my Ocean Revive T247 for a new Xr15 Pro w/ diffuser on my frag tank. Previously I was running the Blue channel at ~50% for 10 hours at day and the white channel at ~10% for 4 hours day. I was hitting about round 250 PAR on my frag rack for the majority of the day. When I set up the XR15 I used my modified AB+ schedule that I used on my main display tank and using my PAR meter set my intensity to match the 250 PAR at max intensity.

So here is my question, is there anything I can expect as far as coloration goes with a change like this. I guess I am thinking, would it be normal if some of the corals lost some some color and went a little brown as they adjust to a new lighting source. I know it has only bee a couple days, but I don't know if what I may be seeing is the corals actually reacting to the new lighting or that the spectra is just significantly different and what I am seeing is a result of they way they look under one light vs another.

I am sure plenty of folks on hear have mad a swap like this, I would love to hear some thoughts.

I have also notices that my Euphillia colony has be very retracted for the the past two days. I am wondering if this could be related to the switch in lighting as well.

I'll leave that one for Salty! I can help with lighting hardware issues like DIY but coral lighting isn't something you want me giving advice on! :p

But what good are DIY lights if you aren't lighting corals with them?

Which is why I don't use them! :p I have my Mitras LX7's which are very user friendly. My coral appreciate the fact that I let the pro's do the settings.

But, if other people want to try and build or repair their own, I'm more than happy to help.

The only thing I can think of, if you're hitting the same par you should be ok from that aspect, but is there going to be a significant change in spectrum from the ocean revive to the radion? If you're getting more UV out of the radion then you were the ocean revive your corals may not like it. Even though you're still getting the same par, it may still be good to either run an acclimation program or start with the lights low and ramp them up.

You are totally right about the spectrum differences. It was one of the major reason I decided to ditch the OR lights and go with the radions, I felt like I was missing a good bit of the spectrum and it wasn't all the pleasing to me to look at. I think the UV might also be significantly different, since the ecotechs actually have dedicated UV diodes and I don't think that OR does.

True UV (<400nm) doesn't (or shouldn't) measure on a PAR meter.. so there is that..
Ocean Revive diodes

Special Full Spectrum layout was developed by fellow reefers of both the US and International reefing community: Royal Blue 450nm, Blue 470nm, Cool White 10000K, 12000K, Red 520nm, Green 660nm and UV 420nm,

420 is not UV...........
