New technology LED Filament bulbs LED filament bulbs have remarkable energy efficiency. In fact, they offer up to 90 percent energy savings over ordinary incandescent light bulbs. The 4W power of an LED filament bulb is equivalent to a 40W incandescent bulb Compared to other LED lights, LED Filament lights are omni-directional. They feature a 360 degrees view angle with very clear glass. Light is emitted from four LED filaments uniformly and evenly in all directions, instead of focusing it in a specific area in the way that many LED light bulbs do. A superfluous aluminum die cast for heat dissipation is no longer required LED filament lights are perfect for homes, hotels, restaurants, bars and places where classic style and appearance is critical.
