These lights are great if you're after something affordable. Their most positive point is their brightness, these things can light up a whole room. I can't look directly at them they're so bright! Their downside is that they are powered by USB and the cables aren't very long. They also heat up to be quite hot very fast so I wouldn't leave them on for long periods of time. Overall they are great at their job though.

These are nice and bright, but it's hard to find a USB outlet that can maintain a steady flow of power to keep it from flickering. It also gets dangerously hot after a few minutes to the point where I'm not sure where to place it without causing a fire hazard.

Very good brightness, but runs very hot, very quickly. Would only recommend using it in a well-ventilated space.
