i love this powerful little light! its perfect for the price & also is aesthetically pleasing I definitely recommend it

We use this for a 3 gallon aquarium. It works great. Only thing we would change is the way the timer works. It's max setting is 4hrs. The different light settings are nice, it gets brighter than expected.

Update: it has not changed mode on a timer for a while now! Don't know what changed but now it is doing what I need it to do. Not strong enough for an aquarium in my opinion unless you do low light plants. This is a good light for small terrariums or aquarium bowls. The problem is that the 3-color one changes color when the timer turns off and on.

Like it so far after a week. It's decently bright at 5w via multiple LEDs and good for smaller tanks (or for more lamps on larger tank). Love how it captures ripples in water and throws them on plants and rocks in tank and on walls around. Color is common 6500K so fine for plants (though maybe not super optimal with special colors green, red, and blue bumps the picky pros are into). It's compact and simple. Note that there's no timer, dimming, nor gradual brightness when turning on or off. Your fish may thank you for more natural lighting setup, esp if they jump out when scared like bettas or other skittish types. Note also it's meant for rimless tanks and has a very narrow clamp so may not work on a rimmed tank with a lip meant for closing lid. The worst/least important thing is the huge twisty knob sticking far out of the base clamp. It protrudes prominently (see attached photos). It can be turned around to the cleaner side of the mount but that means the wire has to go down inside the tank then do a U-turn back up and out which is worse I guess. It's not a big deal, but it does erase some simplicity and elegance from an otherwise perfectly simple design.
