Overview & Details

Lenmar 3-In-1 LED Emergency Back Up Household Bulb
When the power goes out are you left scrambling in dark drawers for a flashlight? Now you can have instant illumination with this 3-in-1 emergency back up bulb. It performs as a standard, soft white LED light bulb until an emergency happens. When the bulb senses a loss of power it instantly switches on its battery backup system to illuminate your space and help you access what you need. You can even remove it from the socket and use it as a flashlight or hand-held SOS signal. If there's an emergency, don't get left in the dark.

  • Great Item

    Fantastic product! Lose power a lot in Florida, annoyingly. Light comes right on, shuts off when power is restored. Love this. Thank you!

  • Got my bulb just in time...

    For the storm that hit my state last weekend and sure enough, it worked when the power went off due to trees falling on power lines. Just wish it also stopped flooding but will take a bright light during a storm anytime. Every home needs several of these for emergencies. Will be back for more, please keep on sale during this hurricane season.

    I bought this because we tend to lose power during the hurricane season. In the meantime we have had a few power outages and this light bulb has been great. The light comes on and I'm able to continue working in my office.Very easy to install.
