20pk - Ushio 28w 23in 4100K FB28T8 U-Tube T8 Fluorescent bulb

20pk - Ushio 28w 23in 4100K FB28T8 U-Tube Fluorescent bulb Fluorescent 32 watt 4100K warm white T8 u-bend tube features a mini bi-pin base, provides a light output of 2800 lumens at a color rendering index (CRI) of 83 and can last an average of, 20,000 hours. hrough technological advances and the highest grade components, T8 fluorescent lamps can save up to 40% on energy costs with no loss of light over older technology T12 lamp types. The USHIO Ultra 8™ fluorescent series provides an economical as well as environmentally responsible alternative to standard T12 fluorescent lamps. The Ultra 8 lamps utilize protective coatings, effectively reducing the phosphor degradation while increasing lumen output. Advanced halophosphor and triphosphor coatings have also been added to increase the lumen stability and allow higher loading. USHIO Ultra 8 lamps employ a precision engineered cathode guard, which prevents end darkening to ensure maximum light output throughout the life of the lamp.
