The 19BR5/UM80 is a type of cathode ray tube (CRT) made for use in consumer televisions and computer monitors. It was a late-model tube produced in the 1990s and is often referred to as a super-bright CRT. The 19BR5/UM80 has an aperture grille pitch of 17mm, which gives it a bright and sharp picture quality with high contrast and resolution. It had some of the most advanced CRT technologies available at the time and was used in some of the best consumer TVs of its era.
