What Are Rechargeable Light Bulbs?
Rechargeable light bulbs are innovative lighting solutions that integrate a rechargeable battery, typically lithium-ion or nickel-metal hydride, with energy-efficient LED technology. Unlike traditional light bulbs that rely solely on a constant electrical supply, these bulbs can store energy and provide illumination even when the power is out. They are designed to function as regular bulbs when connected to a power source and switch to battery mode during outages or when used portably.
The core components of a rechargeable light bulb include:
LED Module: Produces light through electroluminescence, converting 80-90% of energy into light, far more efficient than incandescent bulbs, which waste much of their energy as heat.
Rechargeable Battery: Stores energy to power the bulb during outages, typically lasting 2-8 hours depending on the model and brightness settings.
Charging Circuit: Manages the charging and discharging process to ensure battery longevity and safety.
Control System: Allows features like dimming, color temperature adjustments, and sometimes remote control or smart home integration.
These bulbs typically use a standard E26 or E27 screw-in base, making them compatible with most household fixtures. Some models, like the GE LED+ Battery Backup A21, also double as portable flashlights when removed from their sockets, adding to their versatility.
How Do They Work?
When connected to a power source, a rechargeable light bulb operates like a standard LED bulb, drawing electricity to illuminate while simultaneously charging its internal battery. If the power is cut due to an outage or flipping the switch the bulb detects the loss of external power and switches to its battery reserve. Some advanced models, like the JackonLux Rechargeable Emergency LED Bulb, use a backfeed signal to distinguish between a power outage and a manual switch-off, ensuring the bulb stays on only when needed.
The battery is recharged every time the bulb is powered on, requiring an initial charge of 6-10 hours for most models to reach full capacity. Once charged, the bulb can provide light for several hours, with some offering up to 650 lumens for 5 hours, equivalent to a 65-watt incandescent bulb.
