The Z400SEA-Z has significantly improved the colouration of my soft corals and anemones. The adjustable spectrum helps me match the needs of different species. The light is bright without overheating, and the design fits well above my 120-gallon tank.
Wendy Roberts –
After switching from a halogen to the Z400SEA-Z, my SPS corals have grown more vibrant. The custom schedule feature lets me simulate natural daylight cycles. It’s reliable and easy to set up.
Gordon Oliver –
Great light for reef tanks with mixed coral types. The spectrum adjustment is useful, though I wish the timer options were more intuitive. Overall, it performs well and stays cool during long runs.

I’ve had this light for six months and it’s still running smoothly. The colour accuracy is excellent, and my LPS corals are thriving. The cooling system prevents heat buildup, which is a big plus.
