Features of 4W 220V LED filament bulb

Advanced IC driver, with top class LED filament, clear quartz glass design combine to create an LED lamp that truly replicates the form and weight of an incandescent A19. Provides ENERGY STAR equivalency performance like that of a 40W lamp with the staggering efficiency and life that can only be provided by LED technology. Equivalent Source : 40W incandescent.

1) Super long life span and outstanding safety. Thanks to the unique feature of the mini IC driver, which produce constant current, constant voltage and maintain a constant temperature for the LED filament bulbs.

2)Perfect 360 degree lighting. Without extra heat sink or parts, entirely the same base and shape with standard incandescent bulbs A19 or A60.

3) High electricity-light rate, up to 100-120lm/w light efficiency without extra heat.

4)Competitive to standard incandescent bulb's light effect.

5) Illuminated by several 0.9w/per LED filaments. For example, a 3.6w LED filament bulb lamp consists of 4 pcs filaments, feature with competitive brightness to a 40w incandescent lamp. A 5.4w LED filament bulb lamp consists of 6pcs filaments, perfectly replacing the 60w incandescent bulbs, etc. Customizing sizes and wattages accepted.
