Muscar is a light that you can hold. It is the first lightbulb the can be experienced for its warmth and feel, as well as for its lighting.
Muscar's novel furry coating allows the light to go through while transmitting the bulb's heat in a less concentrated way, essencially making this bulb cooler than any other bulb of similar technology. So muscar can be left on a soft surface such as the carpet, the sofa or a blanket without damaging them. Or it can sit at your lap, while you read.
