With the rise of global environmental awareness, incandescent bulb is banned in various countries successively which drives traditional lighting manufacturers to transform into LED lighting. Aiming for this opportunity, the Taiwanese LED packaging manufacturer, Edison Opto, branches out into filament market and releases 0.8W LED filament. Used in 4W bulb, the LED bulb can replace 40W incandescent bulb, bringing the advantages (energy saving and high efficiency) of LED into full play. Edison Opto can assist traditional incandescent bulb manufacturer in entering LED lighting market.
