This works really good it has 2 different modes and u can make ot brighter or darker it also has a timer if u need it's good lighting for how much it cost

I've had it in my tank for 6 months so far. No problems at all other then the suction coming off sometimes

witch button to push

I love the light. It is bright, and I love that it doesn't have a yellow undertone. It can be turned to shine across, down, or angled. I appreciate being able to light the tank well while leaving part less intense. Great for my apisto's. It is also programmable which is a definite plus.
The only reason it gets 4 stars instead of 5 is the suction cups. It comes with 4 which should be fine. I suctioned it to my tank and it looked great. Half an hour later the suction cups failed. I tried several more times on that 1st day, but they just don't hold.
My plan is to connect the light to my hood with zip ties. Disappointing to have to McGuiver it.

Everything works as intended and I was skeptical about purchasing it at first. I haven’t tried the rest of features as yet
