Trending Power Saver Led Bulb 20 Watt | Lithium Rechargeable - 3.7V 18650 Lithium-ion * 3 Batteries | Indoor & Outdoor | Emergency light backup | Rechargeable Bulb

Stay prepared during unexpected power cuts with the 20W Rechargeable Emergency LED Bulb Light. Designed for both regular lighting and emergency backup use, this energy-efficient LED bulb combines bright illumination with a built-in rechargeable battery system.

Powered by 3 replaceable 3.7V 18650 lithium-ion batteries, the bulb can continue providing light when regular electricity is unavailable. Its automatic emergency operation makes it a practical lighting solution for homes, schools, hospitals, corridors, shops, and other indoor or suitable sheltered areas.

Bright 20W LED Lighting

The bulb delivers 20W lighting output with a rated luminous flux of approximately 1400 lumens during normal powered operation. It uses 37 SMD2835 LED chips to provide efficient and consistent illumination.

With a 6000K color temperature, the bulb produces a bright cool-white light suitable for areas where clear visibility is important.

During battery-powered emergency operation, the rated luminous output is approximately 355 lumens.

Rechargeable Emergency Backup

When electricity is available, the bulb functions as a regular LED light while supporting its rechargeable emergency system. During a power interruption, its emergency function is designed to switch to battery operation automatically under the appropriate operating conditions.

Depending on battery condition, charge level, and usage, the supplied information indicates approximately 6–12 hours of emergency operation.

3 Replaceable Lithium-Ion Batteries

The emergency light uses 3 × 3.7V 18650 lithium-ion batteries. The batteries are replaceable, helping make battery maintenance more convenient when replacement becomes necessary.

For safety and proper performance, replacement batteries should match the manufacturer's required specifications and be installed with the correct polarity.
