This self-reliant X-ray film viewer is made of aluminum alloy material that's anti-corrosive. It has a panel that's acrylic and a flicker-free, stable tri-color Panasonic tube. You can easily open the front panel to replace bulbs or perform other maintenance, and the viewer features a self-reliance ballast so there's no open flash. You can easily install the viewer so it can hang on a wall or be upright. There's a magnetic adsorption bolt that won't hurt the film and many options to choose, from one to ten.
