An inverter bulb is designed to be capable of remaining on even when there are power outages. Therefore it serves as an emergency bulb in case of power cuts. Usually, the bulb has some sort of battery that is inbuilt. This battery that is inbuilt into the bulb charges when there is a mains power supply. Meanwhile, as long as there is the main power supply, the bulb works just like any other (using the grid/AC power). But once there is a power outage, the bulb detects this. Then it starts drawing on the (DC) power it had stored in its inbuilt battery. It is therefore able to remain on, as an automatic emergency light, even when there are power cuts.

Features of Inverter Bulb
- One key feature of an inverter bulb is the light color. This tells us how friendly to the eyes the light coming from the bulb will be. It also tells us how appropriate the bulb will be for use in various circumstances.
- Another important feature of an inverter bulb is the wattage rating.
- From this, you can get insight into the bulb’s power input and output.
- Yet another key feature in an inverter bulb is the voltage rating.
- This can tell you whether the bulb will be compatible with your local grid or not.
- Further, in these bulbs, the luminous flux is an important feature.
- From this, you get to figure out how bright the light from the bulb will be.
Types of Inverter Bulbs
- There are inverter bulbs that produce white light. Then some produce light in colors other than white.
- There are 9-watt inverter bulbs. Then there are 10-watt inverter bulbs.
- We also have 12-watt and 14-watt inverter bulbs.
- We have inverter bulbs that offer long backups: as many as 4 hours.
- Then we have those that offer shorter backups: sometimes even less than one hour.
- There are fast-charging inverter bulbs. Then some tend to charge at slower paces.
Buying Guide for Inverter Bulb
- Firstly, ensure that the inverter bulb you buy is capable of producing good-quality light. In this regard, consider things like the light color of the inverter LED bulb and its brightness.
- Secondly, see to it that the bulb you buy has proper basic safety features.
- At the very least, only buy a bulb with overcharge protection. Also, buy one that has overheating protection.
- Thirdly, consider how easy to install the bulb you buy is.
- Go for a bulb that is compatible with the mains power grid supply system you operate under and only go for one with good-quality connectors.
- Fourthly, consider the inverter bulb price. Only buy a bulb in which there is good value for money: considering the price against the bulb’s overall quality.
How Does It use Inverter Bulb?
- The inverter bulb provides light both when there is mains grid power, and when there are power cuts/interruptions. What makes it capable of remaining alight in the event of power cuts is the inbuilt battery in it.
- When there is a mains grid power supply, the bulb provides light using that (AC) power. But at the same time, it keeps on charging the inbuilt battery, as long as the main power supply is available.
- Now inside the bulb is a circuit that detects when there is a mains power supply cut or interruption. Once it detects this, the bulb instantly starts obtaining the power to remain alight from its inbuilt battery. So it switches from the mode of running on AC mains power, to running on DC battery power. This is what makes it an ‘inverter bulb’.
- If the mains power supply is restored, the bulb detects this too. Then it switches back to drawing power from the mains grid. And it then also starts recharging, storing power for the next outage.
