AA,
Wow! Great picture and nice job hanging the lights! The light spread looks really good to me!
Well to me it looks like I will need 2 for sure if I want the end to end spread for SPS corals!
Are you happy with the results or is it still too early to tell? These are teh only LED's so far that really have me sold. Adjustability seems to be the key and sufficient PAR.
These AI's seem to excell in both departments!
Thank you
Thanks. I wanted to come down from the drop ceiling with the hangers, but there is an AC duct behind the drop ceiling, so I had to hang from the wall instead.
I'm happy with the results I have with 9 units, which is what I bought originally. I bought nine, then bought into the "less is more" hype about these units, and my corals browned. When I went back to 9 modules on my 300, I got the color back.
I think that LED lighting is a choice with some tradeoffs, which goes for
any lighting choice. Halides may be the best for coral color, but have regular bulb replacements, excess electricity use vs LEDs, and heat in the tank, which in most cases necessitates a chiller, etc.
T5s have bulb replacement, heat addition to the tank, etc, but have good rendition.
Leds can provide good color, but I'm not convinced it is as good a that from a halide or T5 bulb, but it may be 90+% of it. But, LEDs have a long life, no bulb replacement, use far less electricity, do not heat the tank, and usually will eliminate the use of a chiller and the electrical consumption that necessitates as well, and give shimmer to the tank.
My experience level is a bit over 6 months at this point, so I have a long way to go, and coral colors can change slowly, so the "as good color as halide" argument is still on the fence for me, but that is what I see so far.
The dimmability feature of the AIs is a double edge sword, IMO. It is nice to be able to do, but using it has caused some folks to have brown SPS corals. What I see from my own local reef club is some folks have less expensive LEDs over their tanks with a set 1:1 or 1:2 white:blue LED ratio, like the eshine units, some without any royal blue LEDs at all, and they cannot adjust intensities it at all, and their SPS corals are great looking, as nice as halides. So in some ways,
not having the ability to dim LEDs can be a good thing IMO, because these folks never had the ability to play with the intensity levels and brown out their corals.
