LED Filament, also called carbon filament, is the latest development in LED field. It combines the very low energy consumption and long life of LED with the exact appearance of incandescent lamps. Enjoy the bright, warm light: a true modern classic. The dimensions of this lamp are 125mm (diameter) x 160 mm (height). The 4 watt replaces 40-50 watts. The energy efficiency class A++ ensures considerable savings. The light intensity is 430 lumens. It is also dimmable. By using high-quality Epistar COG LEDs, a high color rendering can be achieved, namely CRI>80. Thanks to the filament COG LEDs, a light angle of 360º ; achieved and a a really warm light is emitted, such as with an incandescent lamp (2700K or 2200K). Due to this new LED technology, the LED lamp produces an unrivaled light image, which is very well comparable to the traditional incandescent lamp. As a result, you can no longer see from a few meters that you are dealing with an LED light source instead of an incandescent lamp. Read more about this new LED technology on our blog.Note! Only works with (traditional ) leading edge (PWM, TRIAC) dimmers.
