The Aleddra LLT-4-EM-T8-G4-15W-40K is a generation 4 single-ended emergency T8 LED bulb designed to serve as both a standard lighting tube and an integrated battery-backed emergency light. This 15-watt T8 linear bulb operates on 120–277 V and emits a neutral white light at 4000 K, providing practical illumination in regular mode while offering a built-in backup when power fails. Its design accommodates fixtures configured for a traditional T8 with a medium bi-pin base, enabling straightforward substitution in compatible luminaires.
Key differentiating features include a red-striped end wired to an always-on circuit, and the opposite end connected to a wall switch-controlled circuit. The bulb actively senses power conditions, allowing normal on/off operation via the wall switch while ensuring light output during outages. A built-in lithium battery provides up to 90 minutes of light at approximately 420 lumens, and an LED indicator communicates battery charge status. This 2-in-1 construction reduces the need for separate emergency lamps and simplifies maintenance by integrating emergency capability directly into the LED tube.
Practical considerations include its 240-degree beam spread for wide-area coverage, a stated average rated life of 50,000 hours, and a 5-year warranty. When selecting this lamp, confirm that your fixture supports a ballast bypass approach and that the emergency circuitry aligns with the wall-switch-controlled end configuration. Compatible applications include areas requiring reliable temporary lighting during outages without a dedicated emergency light fixture, such as hallways, workstations, and utility spaces where quick, battery-backed illumination is beneficial during power interruptions.
