The Emergency Power LED Light Bulb integrates a built-in, self-charging lithium ion battery into the base of the bulb, which automatically activates in the event of a sudden power outage and will remain illuminated for up to 6 hours. Replace your regular light bulbs with Emergency Power LED Light Bulbs (a.k.a., EBulbs) and you'll be prepared with on-demand light when the power goes out unexpectedly. If you'd like to test your Emergency LED Light Bulbs before experiencing an actual power outage, you can flip your breakers, and the EBulb will come on automatically.
If the lights are on and the power goes out, the lights will stay on automatically. So, if you have the lights off and the power goes out, the lights will remain off, but you can still turn them on normally.
No, you can turn the EBulb off and on just like a regular light bulb using your wall switch. But unlike a regular light bulb, it knows when the power goes out by sensing the differentiating between an open (OFF) and closed (ON) circuit. This means that the built-in, self-charging battery power will activate automatically when there's a power outage.
Yes. They are cool to the touch and can even be powered on like a flashlight when held in the palm of your hand, so you can unscrew it from the light socket and take it with you anywhere you need light in home during a power outage.
The Emergency LED Light Bulb is classified as warm white, which is between 3000 and 3500 Kelvin (the universal scale for measuring color temperature). Most customers classify it as bright white.
Emergency Bulbs work by sensing the availability of electricity in a circuit. When you turn the light switch off, there is still a positive flow of ions in the circuit, but when the power goes out, this positive flow of ions is interrupted (aka, it stops), which is different from the light switch being turned off - the Emergency Bulb senses the change in ion flow. Emergency Bulbs will work with timers that work similar to turning a light switch on and off, where the positive flow of ions still exists. But if the timer cuts the flow of ions, similar to a power outage, the Emergency Bulb will sense that change as if the power had actually gone out. Whether or not the Emergency Bulb will work with your timer depends on how your timer operates.
We have found that Emergency Bulbs are typically not compatible with multi-socket fixtures or runs of lights, as they share a circuit and can interrupt the steady state of ion flow to one bulb sensor. Emergency Bulbs are not recommended for multi-socket fixtures or runs of lights.
