Ours it clamped onto the small side of 2 x 4 of the shelving unit my spouse made. It * on securely. My only complaint is that it can only be clamped on a flat rectangular/ square surface.

Can give either daylightcolored light (blueish) or tungsten colored light (yellowish) also has two brightness levels. One switch allows you experience softer or brighter light.

My favorite feature is the gooseneck which provides good adjustability. The arm is very flexible and the clasp is very strong. It bends well and holds its position nicely.

Works well and has good brightness for my application. The brightness is great. Perfect for illuminating my 6 gallon betta tank.

The build quality gives me diy vibes and i'm somewhat disappointed in my purchase. The outer packaging was torn up and taped like this particular product had been bought and returned at least once before. Stay away from this seller.

Unfortunately the light flickers. It is at random intervals, so unpredictable. Sometimes it doesn't flicker at all. Would be much better if a dimmer.
