LED Filament Bulb

It’s no secret that light-emitting diode (LED) bulbs are far more efficient than traditional incandescent lamps, most notably in that they use only a small fraction of the electricity of an incandescent. As traditional incandescent bulbs continue to be phased out, LED has become the mainstream light sources used on a variety of indoor and outdoor lighting fixtures. However, traditional LED bulbs are not without its disadvantages — the complicated designs which incorporate the heavy aluminum heat sinks and an electronic circuit for power conversion. As a result, the cost is high and the shape is somewhat strange compared with the elegant the incandescent bulbs people are accustomed to.

LED Filament Bulb


An LED filament bulb is a light bulb that uses LEDs as its filaments. 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. It features a close resemblance with the traditional incandescent bulb. Nevertheless the LED filaments are placed inside the glass enclosure in four sides to make sure that light is spread in all directions. A superfluous aluminum die cast for heat dissipation was no longer required. LED filament lights are perfect for homes, hotels, restaurants, bars and places where classic style and appearance is critical.


These bulbs also distribute omni-directional light. They feature a 360 degrees view angle with very clear glass. This is contrary to other LED bulbs that provide light in only one direction. A crystal clear glass bulb and the creative arrangement of the tiny LED bulbs make this multi-directional lighting possible. While keeping the elegant shape and shining light, the high quality light, with 470 lumens output, remains as clear and bright as a 40W incandescent bulb. There is no delay in illumination when switched on. All the electronics is nestled inside the screw base which is almost not visible. The light produced by these bulbs is incredibly similar to natural light. But it does not have any infrared or ultraviolet radiation and it is uniform and soft on the eyes.


This bulb fits well into all the lighting fixtures that used the outdated incandescent light bulbs. After the regulations that banned the sale of the traditional light bulbs, several homeowners could not put in compact fluorescent bulbs or other bogus LED lights into most of these old fixtures and chandeliers. But the LED filament light design makes it easy to reuse these old and attractive lighting fixtures.


LED filament bulbs have remarkable energy efficiency. In fact, they offer up to 90 percent energy savings over ordinary incandescent light bulbs. For instance, if you obtain an LED bulb that uses 4W, it will offer the same amount of illumination of an incandescent bulb with a 40W rating. Currently, there are bulbs that provide daylight (4500K or more) at 9 watts while others that produce a warm white (2700K) or yellow glow consume 6 watts or less.

Long life is a distinguishing feature of these LEDs. Most bulbs are built to last for more than 30,000 hours of use. This extended lifespan is enhanced by a constant current source that ensures stability of parameters and prolongs the life of the bulb. Hence, the cost of investing in these bulbs will provide cost savings for up to 4 decades in some cases. That is why most manufacturers back up their products with warranties that last for up to 10 years.


The LED filament bulb is usually used in places where incandescent bulbs had been used before. For instance, it is used indoors in homes and offices. It also used in commercial environments such as hotels, restaurants, shops, and supermarkets.


The bulbs can also be placed in places where dimming of lights is necessary. These LED lights give off a warm inviting golden soft glow when used in table lamps or as accent lights. They are perfect for creating a very pleasant atmosphere in sitting rooms or bedrooms. Our LED filament chandeliers are, in particular, suitable for decorative and ornamental lighting fixtures.
