I bought the 18″ size for my tank which is an 18″ cube. It’s low tech planted shrimp setup and this light has been great so far. My plants are growing well so I can recommend this light gladly.
Simple light weight doesnt bend the braces they sell for lights light the plant light they have brings out the color in my plants color changing sunrise/set
I absolutely LOVE this light! After you set it up and get the time perfected, this thing is great. Set it and forget it!
Quality product that lights my tank very well!
I just got the order and just set it up in my tank. Hopefully the plants will love it. Attached the Pic so everyone can see the lights results in the tank. Make it so much prettier. This is my 2nd hygger light for my 2nd tank. You can see from the Pic of the two hygger lights from 2 different tanks. I need to reviewed the other light. I love it and highly recommend for ppl to get it to make their plants happy. Aquarium Plants need 2 things to balance them out. Lights and nutrition. Best of luck all. BTW CHECK OUT MY PLANTS. THEY GROWING BIG.
This light is great! Well worth the money.
Great fix end to end. Timers work great…The lights really bring out the colors of the fish!!! Once you buy it you wish you would have done it sooner.
Plants are growing fast. What a difference in a quality light.
