Review on 🌈 Black Light Strip USB UV LED Strip - Waterproof, Super Bright, 6.56FT/2M Length - Ideal for Fluorescent Dance Party, Body Paint, Stage Lighting (USB Powered) by Ashley Gauthier

I make a lot of shadow boxes and this UV light strip gives a very cool ethereal glow to whatever I place using white cardstock. The 3M adhesive on the strips sticks beautifully to the inner frame and holds in place. After about 24 hours I notice much better adhesion and after that it's really difficult to remove it from projects if needed. They do get a bit warmer after a few hours of wear, but they don't feel warmer than warm, and I haven't had any adhesion issues once they've been on and warmed up, or the shadow boxes got hot. inside, but I make vents in the back as a precaution. They can be used on light strips around appliances or under cabinets, but I find that they aren't battery operated, which makes them difficult to place anywhere, and you need to have enough length to get to an outlet. They are really easy to cut and installation is as simple as removing the backing and placing where you want.
