In addition to full-spectrum lighting, it includes a Day-Night dual timer with Sunrise-Day and Sunset-Moon settings, adjustable with 9 color options for planted tanks.

The thick aluminum construction enhances heat dissipation efficiency, and the detachable adapter allows easy replacement without needing to replace the entire light if it becomes damaged.

Light itself is great, programming can be a challenge. The brackets didn’t work well with my rimmed tank. I had to buy another set of brackets with a wider base.
Very well built and sturdy. Light features are great and bright. Perfect size for my small aquarium.
I got this light for both my 30 gallon fish tank and my moms 10 gallon fish tank. We both love it a lot, but unfortunately my mom broke hers pretty quickly because the remote isn’t waterproof. Thats something to be mindful of and I do wish it was a little more obvious. I am however getting a replacement for her as she loves it so much and she’ll just have to be careful this time.
Light is amazing with all the color changes. Plus they helped us out with a fish filter. Thank you hygger
Ì love your products. It a ok ways seems to be a pain to do your surveys. Hard to do for some reason. Keep up great product wor
Unpacked and set up in minutes. A quick Youtube video to clarify how the timer works, and it’s running like a charm. Using it on a planted Neocardina Shrimp tank, and it’s been running like a dream for the last month.
