Just got these 10W UV bars for my room and they're... interesting! The magnetic mounts are super handy - stuck one on my mini fridge instantly. The glow effect on posters is cool, though not as intense as club blacklights.

PROS: Easy USB power (works with my laptop), lightweight, and came with ALL the mounting options. The 1ft size is perfect for small spaces - I used one to highlight a neon painting above my desk.

CONS: They do get warm after hours of use, and the light spread is uneven. My friend's body paint only glowed directly under the bars. Also tried using a power bank like advertised - total fail. Lights wouldn't turn on at all.

Verdict: Good for small decor projects if you manage expectations. Would I buy again? Maybe for the price, but not for serious blacklight needs.
