The right inverter bulb depends on the room size, brightness requirement and desired backup. Orient Electric offers 8W, 9W, 12W and 15W options, with up to 4 hours of backup. For everyday home use, choose the wattage that provides sufficient illumination for your space while also meeting your backup needs.

An emergency bulb works like a regular LED bulb while electricity is available and charges its built-in battery at the same time. When the power supply goes off, it switches to battery power to continue providing light. Once electricity is restored, the battery starts charging again automatically.

You do not generally need a separate charger. When the bulb is installed in a compatible holder and connected to the regular power supply, its built-in battery charges automatically. Keeping it connected during normal electricity supply helps maintain the available backup for the next power cut.

Among the available Orient Electric variants, the 8W inverter bulb is priced at ₹185, followed by the 9W at ₹190, 12W at ₹218 and 15W at ₹325. The best choice should be based on the brightness and coverage you need rather than price alone.

If you mean backup during a power cut, this range provides up to 4 hours of uninterrupted backup, depending on the model and operating conditions. The overall lifespan of the bulb and battery is different from its backup duration and can vary with usage and charging conditions.

First, switch on the bulb with the normal power supply available and allow its battery to charge. Then switch off the mains supply. A properly functioning inverter bulb should continue illuminating using its stored battery power. If it does not, check the holder, power connection and whether the battery has had sufficient time to charge.

The 12W Orient Electric emergency bulb is priced at ₹218, inclusive of applicable taxes. It provides up to 4 hours of backup and is designed to provide illumination during power cuts.

Yes. Rechargeable light bulbs are designed to store electrical energy in an internal battery and use that stored energy when the main power supply is unavailable. This makes them useful for maintaining lighting during power cuts without requiring a separate emergency lamp.

A rechargeable bulb can generally be used in a compatible lamp or bulb holder, provided the base/fitting, wattage and electrical specifications are suitable. Check the bulb's specifications and the lamp holder before installation rather than assuming every rechargeable bulb will fit every fixture.

A rechargeable bulb is an LED bulb with a built-in battery that stores energy while electricity is available. During a power cut, the stored energy allows the bulb to continue producing light, combining the everyday function of an LED bulb with convenient backup lighting.

The backup duration refers to how long the bulb can provide light after a power cut, while the overall product lifespan refers to how long the bulb and battery remain usable. Orient Electric's emergency rechargeable bulbs can provide up to 4 hours of backup, while actual performance can vary based on usage and operating conditions.

For home use, look for a charging bulb that provides sufficient brightness, dependable battery backup and automatic charging. Orient Electric offers 8W, 9W, 12W and 15W options, so you can select a suitable model based on your room size and illumination requirements.

Not necessarily. A charging bulb uses electricity to operate its LED and recharge its built-in battery when power is available. Its electricity consumption primarily depends on the bulb's wattage and usage duration. The charging function itself does not mean that the bulb continuously consumes significantly more electricity than its rated operation.
