The CALUS LE2 Dual Battery Emergency Lamp is a highly efficient, rechargeable LED emergency light bulb designed to automatically provide illumination during power outages. It is an upgrade to the standard LE1 model, offering twice the battery capacity for longer operational hours.
Core Product Features:
- Dual Battery Setup: Powered by two built-in rechargeable batteries (typically 18650 type) to deliver extended backup runtime compared to standard emergency bulbs.
- 20W Output: Delivers standard high-brightness LED lighting while saving up to 90% energy compared to traditional incandescent bulbs.
- Standard E27 Base: Screws into standard household light fixtures, operating and charging normally when the main power is on.
- Automatic Fail-Over: Features smart circuitry that instantly detects power cuts and switches on automatically using its internal battery backup.
- Portability (Human Induction): Includes a detachable hook/cap switch, or can even be illuminated by simply bridging the base contacts with damp fingers to act as a portable torch or camping lantern.
Standard Usage and Charging
- Regular Operation: Use the bulb like a standard light fixture. It will charge its dual batteries in the background while the wall switch is turned on.
- First-Time Charge: It is highly recommended to charge the bulb for at least 4 to 6 hours during normal power availability before relying on it for an emergency.
- Emergency Activation: When the electricity drops, keep the wall switch in the “ON” position. The bulb senses the broken main circuit grid and stays lit.
