LED Filament Bulb (CCT Adjustable - Switching Control) is simple designed product to simplify  CCT changing needs of LED Filament Bulb for indoor usage. The product uses a mixture of warm and cool color LED chips to achieve 3 color temperature switching. With repeated on and off switching, color temperature of the  bulb will change from 6500K to 4000K and then to 3000K, without any additional device such as dimmer or remote control. The product has built in chips with memory functions, which the light color will be remembered for longer switch off duration (instead of instant on and off). The product is certified by TUV and SGS with CE, RoHS and ERP and SAA.

Our filament bulb uses a fully encapsuled ceramic filament base with high quality Sanan & Epistar chips. The whole lamp has a high lighting efficacy of (100lm/W – 120lm/W) and color rendering (CRI80-95). We offer full range of color temperature, ranging from 2700-6500K. The product beam angle is 360°.

For bulb body, it uses opal glass for have more diffused light effect, and so as to ensure good color temperature changing effect. The base cap could either be Edison screw or bayonet type. They can be of size E12 | E14 | B15d | E26 | E27 | B22d. The base cap could be made of aluminum in slivery color or copper in golden color.

LED filament bulb use high quality Linear IC or IC driver to power on, which could be single voltage input (AC120V or 230V) of power factor >0.5. Compare to traditional dimmer switch-controlled dimming, smart filament bulb does not have dimmer compatibility issue and can 100% ensure a smooth dimming effect, and it could save the effort in connecting a dimmer switch to the exiting circuit. The lifetime of the product is over 25,000 hours, with a warrant period of 2 years.

Filament bulb could have a wide range of applications. They can be used to upgrade home fixtures such as ceiling lamps, table lamps or spot light fixture at home with dimming and CCT changing functions. If you prefer to work or read with cooler light color, or you prefer your dinning environment to have warming light color, you could achieve this by simple on and off switching. The product is also highly favorable for multiple function hotel room which meeting and dining area no longer require redundant lighting products. They can also be used in shopping malls and shops for both decorating or lighting purpose. The product could also allow more customized lighting effect in bars and restaurants. For customers working with lighting projects for DIY shops of homewares mart, a more customizable lighting solution will always draw customer attention towards modern lighting and home decoration.
