The SEAOURA LED Aquarium Light (model SR-616) is a full spectrum light for freshwater tanks 12-18 inch long. It adds features usually found on bigger lights: a built-in timer, 10 level brightness and three color modes.
Timer
The timer key offers three choices: run for 6 hours, 10 hours or 12 hours. The light ramps up over 15 minutes at the start and dims over the last 15 minutes, which is gentler on fish than switching straight on and off.
Brightness and color

- 10 level brightness plus on/off
- All lights on
- White/Red/Green/Pink
- Only Blue, as a night light
LEDs

SEAOURA uses SMD2835 chips in 5 columns, with 6500k white plus red, pink, green and blue. The color rendering index is up to 89%, close to natural light, so fish colors look accurate.
Build

The ABS shell dissipates heat, and the extendable metal bracket fits most small tanks. A memory function keeps your settings after a power failure, and the timer restarts counting when power returns.
Plants
Full spectrum light with red helps plant growth. Start around 6 hours at moderate brightness in a new tank and increase as plants establish; too much light too soon tends to grow algae first.
Compare
For a similar small light with a set daytime and night mode, see the Pawfly 11W LED. For a clip-on with a 24/7 sunrise cycle, look at the hygger clip-on 14W.
Who it suits
Keepers of small freshwater and planted tanks who want timing and dimming in one compact light. SEAOURA offers a 1-month free return. The ramp-up and memory features make it a low-maintenance choice for busy owners who want a consistent daily cycle.
Because the timer restarts from power-on, plug it into the wall at the time you want the light to start each day, or reset it once after any outage.
The Bottom Line
A feature-rich small light for nano and planted tanks.
