Review on 🐠 Hiro Aquatics WRGB Full Spectrum Planted Aquarium Light: Timer, Adjustable Brightness - Ideal for High Tech Freshwater Plants by William Dean

Good: The light is very bright and illuminates the pool well. Very quiet operation despite built-in fan. Cons: The timer on the backlight is unreliable. It turns on 5 minutes earlier each day and resets the lighting schedule if you leave it unattended for a week or two. Turning on an external timer didn't help either, unless you can use the light's brightness at 100% power. So if you buy that, you will get the weakest performance. Review Edit: Now that I think about it. The rating should be 3 stars as a synced light that doesn't have a proper internal clock defeats its purpose. I would look for other lamps at a cheaper price.
