Simply brilliant. We’d like to shake the hand of the person who was smart enough to create this device.
Self Charging Smoke Alarm
Never worry about changing batteries again. This unique smoke detector screws into any ceiling light fixture and operates off your home electricity. Reinstall the light bulb into the alarm, and now you’ve got a light source and smoke alarm in one! Recharges itself every time you turn the light on. Great protection for high-risk areas such as laundry rooms, garages, and workshops. Fully charged, it will operate for up to 30 days in the event of a power loss. Works even if the temperature drops to 5°F. The 85 dB alarm can be heard all over the house! UL listed.
