LEDinside, a division of TrendForce, reports that the global average sales prices (ASP) of LED light bulbs fell in July compared with the prior month. The global ASP of 40-watt equivalent products dropped by 0.9% to US$6.5, while the global ASP of 60-watt equivalent products dropped by 2.8% to US$7.8.

Before 2012, the largest market for sapphire substrate applications was LED and the entry of many players led to an oversupply situation, with most manufacturers still suffering from losses, according to LEDinside analysts. Sapphire substrate prices remained low over the last two years due to this oversupply situation, according to a LEDinside report published in May 2013. Over the last few months, though, developments in the industry especially in the non-LED application field have shown a likely price rebound in 2014.
