“The current market trend shows strong sales of LED filament light bulbs in Europe and the U.S.,” said LEDinside analyst Allen Yu. “Philips for instance released four LED filament bulbs in February and more related products in May. These LED filament bulbs from Philips are all priced below the market average.”

China’s LED package market has seen undersupply since entering the second quarter. Though chip suppliers have taken on additional production capacity, the strong downstream demand have sustained chip prices. This in turn stabilized prices in China’s package market in May. As prices have remained steady, package suppliers are raising the efficiency of their products. Many mid-power and standard packages from international suppliers (e.g. 5630 LEDs and 3030 LEDs) have reached luminous efficacy of around 215 to 220 lumens per watt.
