Designer Arthur Brault has crafted a beautiful lighting that not just illuminates your interiors but works as the smoke detector too. Dubbed Lum, it’s a lighting that looks like any other ordinary pendant and when it detects smoke it raises the alarm to make the home owner cautious. Basically, Lum is an attachment between the light bulb and the socket. Lum’s batteries get charged whenever you switch on the light bulb. In short, it’s an efficient fire alarm that spreads light in your interiors.
