I bought the RayOn-36 for my 4-foot tank. It stays firmly in place and doesn’t sag. The light cycle mimics natural daylight, and my fish seem more active. The warm light is pleasant to watch, and I don’t have to turn it on manually every day.

Works well as a secondary light. The automatic on/off is a big plus. I noticed less algae growth compared to my previous lamp. Only issue is the cable is a bit short for my setup, so I added a 1-meter extension.

Great value for the size. I use it in a fish-heavy tank with some shade plants. The light creates a nice gradient, and my fish swim to the darker areas when it’s dim. Very stable and easy to install.

The lamp works, but I found it doesn’t provide enough brightness for a tank with tall plants. It’s better suited for fish-only or low-light setups. The warm light is nice, but not ideal for high-light plants.
