I am very excited to show you for the very first time on this forum the new ACQ521-50-140M LED Light fixture from Aquatronica. It is a 140watt LED Marine fixture with details of the specifications found here http://www.aquatronica.com/en/product/acq521-m/

The unit has no fans and each row of LED's has it's own heat sink to dissipate the heat making it a very sleek design. It uses a Mean Well LED Driver with waterproof connectors and the ACQ-521 LED Dimming Controller to connect to the Touch. Overall I am pretty impressed with the whole package when compared to Orphek and Aqua Illumination lamps I have owned I the past.

Let's get to the pictures;

Set up the lamp on my IM Nuvo Fusion 20G and it basically covers the entire surface of the tank. There is a smaller 80W unit that might have worked just as well. This light is incredibly bright and can be adjusted to suit your lighting needs with the 5 channels and additional Moon light channel. I am still playing around with the controls which took a little figuring out since there is not much information about the unit. So far I am pretty satisfied with the control of the unit and figure I could grow most anything in the whole tank because the coverage is very good.

Here are some more pics;

Light looks pretty slick did not realize Aquatronica was now selling lights,protein skimmers RODI units,etc
Were you able to purchase it from the Canadian Aquatronica store or did you have to get it from Italy.

dbond - I got the light directly from Italy. I am not sure when it may appear in the Aquatronica store but it would be a shame if it wasn't done sooner than later. I have been using Aquatronica equipment on my tanks since they first started selling stuff over 13 years ago and still using most of it today. I think they are finally getting better and being accessible to the North American market with all their products they sell.

The light is very well built with the unique feature of each led strip having its own narrow aluminum heat sink attached. There is space between the strips to allow air flow around the whole heat sink. This design does not require a fan for that reason. Fans are the biggest downfall on any salt water setup, they never last any length of time.

You beat me to it Nick. I got the bigger brother to yours, it uses two power supplies and is about twice as long. They are great lighting systems and are constructed extremely well with top of the line CREE LEDs. I also like the fact that they don't need a fan because the heatsink is so large. If you have any questions about the programming let me know. It took me awhile to figure out everything and get it going right. You only want to use the Advanced mode, the simple mode is just way too bright and will fry your corals.

Rob, curious as to your light settings on all the channels to get the look you want.

Nick I will take a look at the settings, I have lots of incremental values through the day on each LED set to make a peak in the graph at midway through the tanks lighting time. which is about 90 minutes of peak lighting. I know that none of them go past 70% to get a PAR value that is about 170 near the top of the rock work.

One neat little trick was I made a program that shuts them all off if the Tank gets too hot for some reason. It turns on just the Reds on at 50%. I also get SMS alert, and email alert as well as the normal alarm, but the RED lights really gets my wife's attention that something really bad is happening.
I had it happen one day when I was doing some work on the tank and had manually blocked the chiller outlet and then forgot to unblock it. She called me at about 1pm, about 10 seconds before I got the SMS message. I remoted in VIA my iphone and unblocked the plug and put it back to AUTO while on the road.

Hello fellow reefers,

I am new to the forum, but been in the hobby for about 2 yrs. I currently upgraded to an 80 Gal tank. I am currently in the search for new lights. I own the aquatronica controller and this seems like a great option.

How is your light doing with your corals? any SPS?

What size would you recommend for a 48x16x24 deep tank?

I think Nick is just setting up a new replacement tank so I don't know if he is stocked yet. I just moved from T5s to the Aquatronica lights about 5-6 months ago. So far everything is looking good. I started out on a low setting and bought the lights up to about 170 par near the top of the rocks after about a month of gradual increases. I have SPS near the top and some hammers and torches near the bottom section.

I have started slowly stocking my tank. SPS frags and LPS are doing great. Considering I started with dead rock I am now starting to see areas of coralline algae starting to grow.

So far I am happy with the performance of the light fixture. I've tried an AI Prime on this tank and the AQ appears to provide a comparable performance but better overall light coverage on the IM Nuvo Fusion 20.I took a quick IPhone pic.
