So honestly, I probably have more experience with nicrew’s reef lights than most people. I have over 20 of them that are in use currently and that number will be closer to 30 soon. I’m running gen 1 hyper reefs in the 50w and 100w version, gen 2 hyper reefs n the 100w and 200w version, and the nava reefs in the 135w version. I’m using controllers on all of them.
The gen 1s have been in use for nearly 5 years without issue aside from one power supply going bad. That sort of reliability is tough to beat. The gen 2s are more refined and I do like them better than the first generation lights because I can customize the spectrum more, but my favorite by far are the nava reef 135s. That is an EXCELLENT light, regardless of price, IMO. Nicrew nailed the LED array on the nava reefs. I love the spectrum of the preprogrammed AB+ or whatever it’s called. As my humble little coral farm expands the nava reef will be my go to choice for lighting.
FWIW, I also have radions (gen 5) running as well. So I have experience with higher end/more expensive lighting to compare them to. Radions are fine, but I honestly like the simplicity of the nicrews better, and they will all grow corals just the same.
