MoMA’s Bulb Flashlight has a built-in rechargeable battery that allows it to double as a regular bulb and an emergency flashlight. The $45 LED bulb is recharged while used as a lamp. It screws into a standard socket and produces as much as a 40W bulb using just 6W of electricity. Then, when there’s a power outage or some other emergency situation, the bulb can provide lighting for up to three hours.
When recharging the bulb, it is essential to ensure it is used in a lamp for which 40W of incandescent light is ideal to get the best charge. Then, in order to use it as a flashlight in the event of a power outage, simply unscrew the bulb, extend the “neck”, turn on the switch and voilà, the light bulb will provide three hours of emergency light. This awesome low-heat lightbulb can be purchased at the MoMA store for $45. Members receive a 10 percent discount.
