Smoke Alarm In A Light Bulb

The Lum light bulb is a unique project that makes a smoke alarm/detector a useful handy light during an emergency. The idea is thus: Lum is an attachment between the light bulb and its socket. It draws energy from the bulb in its latent state and when the smoke alarm triggers,it produces a sonar alert and powers the bulb for emergency lighting. In short, during its standby mode, whenever you switch on the light bulb during daily routine,it recharges its own batteries.One cool fire bulb alarm i would say!
