Hey, Kevin,
I have the Pacifc Sun and its an amazing light. Here are some brief thoughts...
Customer service and support: i believe the company is located in Poland so customer support is delayed but has always been good. It has taken a couple of days sometimes to hear back from them but I always for a response. There may also be a bit of a language barrier but nothing that couldnt easily be worked through. They walked me through the entire set up process and were very helpful. When I got my light there was a helpful forum on RC that they responded to but I think they dropped their sponsorship and all the posts were removed. That was a great resource so its a bit of a bummer.
Interface: I am not a "techie" so the interface was a bit cumbersome for me at first. The guys who are at all tech savvy seem to love it. The programming is more advanced for PC than it is for Apple but both work fine. The common complaint I read is that it is Bluetooth and not Wi-Fi but this hasn't been a big deal. The control and programming of times, colors, storms, moon phases, etc, etc. is great. It also has a preprogrammed acclimation program where you can select what kind of tank you are currently running and what kind of corals you have and it automatically adjusts the intensity over time.
Performance: the light itself is great. I just had a big loss due to a power outage so I can't show you pics but it can easily maintain all kinds of corals. You don't get the shimmer effect as strong as you would with Halide or all LED but the LEDs are strong enough to add some shimmer even with the T5s on. The fans are quiet and it looks great. One note, on the color spectrum there is no "white" for the LED's. This is my first time with LEDs so I dont know if this is normal or not. You can make it look more white using other color options but i thought that was interesting. I like a more 15-20k look so its never been an issue. You can always take blue out and change out the T5 bulbs if you wanted a different spectrum.
I have the 36" with 2 LED panels and 4 36" T5's and it is more than enough light for my 48" tank that is 20" deep. I may end up having to downgrade in the next month and this light will be the hardest thing to part with.
Hope that helps. Im kind of a plug and play guy with the tech stuff but if you have more questions I can try to help.
