now $17.99. 7W Tess Bulbs, equivalent to 40W incandescent bulbs, were $34.99 and are now $19.99. 9W Tess Bulbs, a 60W replacement, were $39.99 and are now $21.99.
Elemental LED introduced the Tess Bulb to its catalogue last year as a top-of-the-line product with significant improvements in function and light quality to that of its LED replacement light bulb predecessors. Tess Bulbs are UL listed and feature Cree LED chips, top-rated for their brightness and energy-efficiency. According to Cree, “Cree LEDs combine highly efficient InGaN materials with proprietary G•SIC substrates to deliver superior price/performance for high-intensity LEDs.”
The prices of LED light bulbs and fixtures are decreasing dramatically throughout the industry, making them an economically viable option for consumers. The price decrease follows similar trends of other consumer electronic products, for which a gradual increase in demand and consumption leads to a dramatic lowering of prices.
Features of the Tess LED Light Bulb include no flickering or humming, a durable housing that is difficult to break, no warm-up time required, and no mercury. Containment of toxic mercury, flickering, humming, fragility and slow warm-up are all well documented problems with CFLs. The Tess Bulb lasts for 50,000 hours, 10 to 50 times longer than a standard incandescent bulb or CFL, and uses 20% as much energy as an incandescent bulb.
The Tess Bulb is available in a warm white colour temperature, which creates an inviting, smooth, even light for indoor living spaces. It is also available in neutral white, which works well against metal and cool colour tones or outdoors.
The decrease in prices by Elemental LED signals that the company is positioning itself as a viable competitor to big box retailers. “We are top of the market when it comes to quality and customer service,” says Director of Business Development Matthew John, “In the past some of our competitors have beat us in terms of price, but that is quickly changing.”
Osram to sue LG and Samsung
The firm wants an export ban against LG LED products out of Korea. The LED giant has also filed nullity suits and infringement actions against LG and Samsung, in particular for what it says is patent infringement on its white light LED technology.
Osram and Osram Opto Semiconductors have filed a complaint against LG Innotek with the Korea Trade Commission (KTC).
Osram has also filed nullity suits and infringement actions against patents and companies of LG Group and Samsung in Korea. Osram is convinced that these companies are infringing core patents of Osram in Korea. LG and Samsung have already filed the respective claims in Korea in June this year.
“We respect the property rights of other companies and expect the same from other market participants. Our most important competitors have acknowledged our patents by entering into cross- license agreements with us or paying royalties,” stated Aldo Kamper, CEO of Osram Opto Semi. “That is why we are setting a clear signal with our actions in Korea, not least for our customers, for whom we are a reliable partner.”
In the filing with the KTC, Osram alleges that LG Innotek infringes four LED patents for generating white light. Such LEDs are used for instance in display backlighting for modern TV sets and computer monitors. Osram is requesting the KTC to issue an order banning the exports of certain LG LED products from Korea that are manufactured using patented Osram core technology.
In its infringement actions with the Seoul Central District Court, Osram stresses that LG Group and Samsung companies are infringing Osram’s patents on white and surface mountable LEDs in Korea and is therefore requesting these companies to refrain from the unauthorised use of Osram technology. What’s more, Osram is claiming damage compensation and has filed nullity suits against patents that both companies asserted against Osram. Osram says these patents are null and void.
In June 2011, Osram sued LG Group and Samsung 52
