Aleddra’s Gen4 Emergency T5 lamp sets another industry standard as the first self-testing/self-diagnosis T5. The lamp operates as an energy-efficient T5 during normal operation and can be turned on/off via a wall switch. During power outage, it will last over 90 minutes on battery. More importantly, the lamp will automatically self-test for 30 seconds monthly and for 90 minutes annually, thus meeting the emergency lighting audit requirements with no labor cost. This saves a facility management team a tremendous amount of labor from manually testing every single lamp of this kind in its facilities. Should any malfunction be detected during self-testing, such as insufficient battery capacity, the warning indicator on the lamp will flash and alert the team. With its labor saving, the lamp gives the end user the best return on investment and the best emergency lighting option. Please follow the installation instruction to wire the lamp.   LISTINGS AND CERTIFICATIONS     90 minutes battery time per industry standard ETL Certified DLC Listed FEATURES 2-in-1 tube: regular T5 lighting and emergency lighting Manual testing button Automatic self-testing: 30-second test monthly and 90-minute test annually Self-diagnosis with flashing indicator if the battery time drops below 90 minutes Built-in lithium batteries Controllable by wall switch Easy battery shutoff switch for a long stocking time Patented 5-year warranty SPECIFICATIONS Length 4ft Color 4000K, 5000K Battery Operating Temperature 50°F ~ 110°F CRI >80 Input Voltage AC1020-277V Light Output 2900lm Emergency Time 90 minutes Wattage 22W Light Output When on Battery 420lm at 3.5W Power Factor >0.92 Luminous Efficiency >120lm/W Rated Hours 50,000 hours Warranty 5-year *
