I've had my Sky's up for a week now and overall I really like them. I have 3 over a standard 180, I could have gotten away with 2..maybe but the intent is for sps so I added the 3rd.
1. My corals have better polyp extension than they have ever had so that's a good thing.
2. I like the weight of the light it makes it easier to mount because a simple drywall anchor will hold it.
3. The diffused light is not a joke I minutes one as directly as I could over the brace with an ecotech mount and it left no shadow that you could see or read with par meter.
4. Able to get much more consistent par readings with my MQ-510 than I was previously. Par meter used to jump significantly.
5. I like the ease of setting up a light schedule and options for how you want it to look.
6. Initial setup was king of a pain in Apex modules needed updated which doesn't make a lot of sense to me being fairly new on the
market but whatever. I also had them setup with Bluetooth originally then switched to apex so maybe there was some issue there but I found the Bluetooth setup much easier.
7. Don't be confused when they say you can daisy chain them together, that's only to connect to apex not for a power source. I heard that comment in a video and thought awesome one power cord. But when you think about it that doesn't make sense.
8. Another negative is it will show you all the little spot the GHA you are battling is hiding and it looks extra ugly. But I guess I know where to attack it.
Overall I am happy with the lights I guess time will tell on how reliable etc. they turn out to be. I had a reef breeders previously which served me well for over a year until my 120 started leaking and I moved to a 180 it wouldn't cover the tank so I needed new lighting anyway.
Hopefully that gives someone an honest viewpoint from a fellow reefer who actually bought the lights.
