With a powerful 380nm UV LED, adjustable angle, and 10 degree glass lens, the UV spotlight gives precision illumination where you need it. Using the included remote control, you can make glow-in-the-dark products come to life with the push of a button. Spot diameter is determined by adjusting the distance between the spotlight and the area/objects to be illuminated; the spot diameter increases approximately 3in for each foot after 1ft. Thus, you will have a 2in diameter at a 1ft distance, and a 26in diameter at a 10ft distance. With dual support brackets, you can choose between rack mount or free-standing. 4V DC adapter is included. Great for parties or dance events, as well as for Halloween displays.
