business lighting has been switching to LED lighting at a healthy rate

Lextar's LED lighting is divided into two business lines, including accepting OEM orders from international lighting firms and cooperating with customers in different distribution markets. Lextar added that accepting OEM orders from international firms can help keep it up to date with market standards and trends while the latter business line can help the firm to understand the differences of each market.Lextar pointed out that even if the market price of led high bay light eaches a sweet spot, it is unlikely to stimulate explosive demand because lighting needs time to commercialize. On the other hand, said Lextar, business lighting has been switching to LED lighting at a healthy rate, causing demand for high-power COB products to grow rapidly. Lextar stated that growth in Japan and Europe has been the strongest.Osram announces major progress on silicon substrates in January. Potentially cheaper than sapphire, it appears possible the silicon substrates may be shipped in volume in 2013.
China turns to U.S. suppliers in an official backlash against domestic LED streetlight quality problems.The city of Chongqing, in June, completes China’s largest LED street lamp installation, using 1.9 million Cree LEDs in 20,000 lights on 119 streets. China momentarily claims four of the world’s five largest LED streetlight installations.The Osram non-IPO twists in the euro wind. LED investors and founders hoping for a headline exit story will have to wait until 2013. Siemens revised its IPO of Osram into a share conversion and then delayed it repeatedly as the Eurozone struggled.Eighteen months ago the cost of LEDs was prohibitive. Only this year did it become a viable option. We opted for GE Lighting’s second generation range of LEDs because not only did it meet all of John Lewis’ lighting criteria but it had a twist and lock capability which I wanted to embrace. It means we can re-lamp easily and just replace the LED chips.”

GE Lighting’s rapid development of the Infusion modules means Ayling has already decided to replace the Ipswich store’s second generation chips (fitted in November) with third generation chips next February. At 1500 lm (23 watts), the efficacy of the second generation Infusion LED modules is 65 lumens per watt but this will increase to 94 lumens per watt in the third generation LED chip fitting. Once installed, the new lighting benchmark in the store will be seven watts per square metre.The LEDs were fitted after Ayling conducted pilot tests of different lighting products at John Lewis stores in Oxford Street and Stratford as part of an 18-month process.Ipswich is a line in the sand as to whether as a business we will continue with LEDs or stick with ceramic metal halide,” he said. “The shop staff, customers,procurement and led flood light team are happy, so we won’t be going back to ceramics. LEDs are working for us. Lighting is the biggest step change needed for CSR targets. LEDs would make between a 15 and 20 per cent energy saving across the business.”
