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.
