Simply Conserve 5 watt Battery Backup With Hook LED Bulb ? keeps the lights on when the power goes out. A power outage shouldn?t mean complete darkness. That?s why the Simply Conserve Battery Backup Lamp functions like a normal light bulb ? until it?s needed most. When the power goes out, the bulb stays on by operating in back-up battery mode. It charges when the light is on, so it?s always ready to shine. Also included with the bulb is a hook power cap that easily screws onto the bulb, enabling it to be operated like a flashlight. Alternatively, the bulb can be hung anywhere for hands-free light without power. The bulb can also be turned on by touching the top and sides of the metal base with moist hands or a wet cloth. Its damp-rated functionality also makes it a popular choice for outdoor usage in gardens, camping trips and more.
