FLASH-NIGHT / flashlight-night

We are afraid to wake roommates up when getting out of bed during the night with the headlight on. And we always cannot find the flashlights once we are in urgent need of them. Also flashlights working by ordinary batteries are always out of work.
Flash-Night is able to solve the problems above. First, the lithium battery can store electrical energy to make bulbs continue to work when there is no electricity. Second, Flash-Night disassembles easily. We can pull out the lamp bulb from Flash-Night and then it becomes a flashlight. This function can meet our emergency needs such as getting up at night and running into a power failure.
