Romantic dinners, late night reading, worried about affording your electric bill, or a karaoke concert in your living room could be some of the many reasons you would need a bulb that will shine specifically where you want it, and nowhere else.

The EcoBulb (designed by Seokjae Rhee) does just that: shines where you would like it to, without using the entire bulb. Did we mention you control this function via a remote control? There are households that have many lightbulbs in each room (we're one of them), and some argue that's just wasteful.

The Ecobulb can be used to illuminate an entire room, or you can click that little remote control and use just a fraction of the bulb to focus on one portion of the room. This will allow for the bulb to outlast any other LED bulb on the market and lower your energy bills.

Whether these lights will come on the market is undecided &mdash Do you think there's a market for the EcoBulb? If so, would you use it?
