Like a finely tuned European automobile, this Ushio T8 lamp uses proven German technology for problem-free performance and reduced burn-out. With 800 series rare earth tri-phosphors, the Ushio 3000260 F17T8/835 fluorescent lamp saves 40% in energy costs over older T12 lamps, without any loss in light. Protective coatings within the Ultra T8 reduce phosphor degradation, while precision-engineered cathode guards prevent end darkening to ensure maximum light output throughout the 30,000-hour life of the lamp. With a 3500K color temperature and a CRI of 86, this versatile fluorescent lamp is suitable for paint stores, retail shops, clothing boutiques, hair salons, printing businesses and graphic arts studios.
