How to Choose Battery Backup for Light Bulb?

The battery backup light bulbs will continue to illuminate your residence in the event of a power outage, even though they appear to function identically to standard light bulbs on an average day. While traditional methods can still be used, they will continue to provide illumination at a lower wattage than when the power is on.  

Charging Time

It is essential to consider charging time, as some devices advertised as lasting longer during a power outage will also require longer charging times. Consequently, paying close attention to the load-shedding schedule is essential to ensure you have allotted sufficient time for charging.      


The LED light uses less energy to achieve comparable luminosity than traditional incandescent bulbs. For instance, a 13W to 15W LED light emits approximately the same light as a 60W incandescent bulb.    

LED illumination is also measured in lumen units, which provide a much more accurate representation of a bulb's brightness. However, when shopping, primarily online, the watt measurement is more likely to appear in the product description, so it is crucial to understand its relationship to lumen units.  

LED Types

When provided, pay close attention to the lumen measurement difference between standard and emergency use, as some less expensive options may need to be brighter for your requirements in a power outage. If you are still determining the bulb's brightness in emergency mode, you should purchase a solitary bulb and test it before buying a set.         

Depending on the application, an outdoor light will likely need to be significantly brighter than an indoor light, mainly for security purposes. Therefore, it is essential to consider the luminosity, beam angle, and battery size. Numerous rechargeable LED outdoor lights have the potential cost-saving benefit of being solar-powered if the included solar panel is located in an area that receives sunlight during the day.
