Dp Led Light Led Light Smart Intelligent Emergency Rechargeable Bulb (Remains on after blackout) 5w,7w,9w,12w and 15w

These bulbs are available in various wattages (5W, 7W, 9W, 12W, and 15W) to suit different room sizes and lighting needs. 

• Dual Functionality: They work as standard LED light bulbs when the main power is on, providing bright, energy-efficient light while also charging the internal battery.
• Automatic Emergency Mode: A power detection sensor automatically switches the bulb to battery power within milliseconds of a power failure, provided the light switch is in the "ON" position.
• Integrated Rechargeable Battery: Typically a lithium-ion battery (around 1200mAh-3000mAh capacity), the battery provides emergency power for approximately 2 to 4 hours, though some high-capacity models may last longer.
• Energy Efficiency: Utilizing advanced LED technology, these bulbs consume significantly less energy (up to 80% less than incandescent bulbs).
• Long Lifespan: LEDs offer a long operational life, typically around 25,000 to 50,000 hours, reducing the need for frequent replacements.
• Standard Compatibility: Most models use a standard E26 or E27 screw base, allowing for easy "plug-and-play" installation in existing fixtures without any special wiring.
• Portability: Many versions include a portable hook attachment, allowing the bulb to be removed from the socket and used as a flashlight or for camping and outdoor activities. Some can even be activated by touching the base with a finger or placing it in water.
• Safety Features: The charging circuit usually includes protection against overcharging and over-discharging to maintain battery health and ensure safety.
