5v light strip lamp holder

My small fish tank never had a suitable small light, either it was too big, or children looking up from below would be blinded by the glare

Later, I thought of making this rotating cylindrical light stand, which can rotate to adjust the angle (Since I didn't design gears, I could only make a smooth cylinder)

I just bought a random PDD COB LED strip, 5V self-adhesive and trimmable (with USB). The price was 3.98

Then, pairing this light stand with an idle power bank provides convenient power at night

The buckle is designed to clip onto 5mm fish tank glass. I upgraded the buckle by adding a ring, so the light can rotate 360 degrees without falling off

The frame for the LED strip has an outer length of 18cm, and an A1 mini can also print it

V2 Update on April 6, 2026, 23:06

Modified and optimized the light stand buckle, allowing its light tube to rotate 360° for arbitrary adjustment (The V1 version had too few adjustable angles, and rotating it too much would cause it to detach)
