PUR cable is a type of cable that is specifically designed to withstand exposure to oil and other petroleum-based substances. The sheath of the cable is made from a material called polyurethane (PUR), which is known for its resistance to oil, chemicals, and abrasion.

While other companies have announced results above the 100 lm/W threshold, these have all related to small devices driven at 20 mA. For example, Nichia recently announced a 150 lm/W lamp-type white LED demonstration (see news item ). The Lumileds announcement shows that developments in the power LED segment are keeping pace with standard LEDs.
The white LEDs developed by Lumileds Advanced Labs are built around 1x1 mm 2 chips. The devices delivered 136 lm when driven with a current of 350 mA, corresponding to an efficacy of 115 lm/W. Lumileds emphasizeds the correlated color temperature (CCT) of 4685K, which is significant lower than values ​​typically reported.
Equally impressively, at 2000 mA the white LEDs delivered 502 lm, corresponding to an efficacy of 61 lm/W. Lumileds says that it achieved these record results for white LEDs by combining several new and innovative technologies, including breakthroughs in epitaxy, device physics, Phosphors, and packaging technologies.
Steve Landau, Lumileds worldwide marcom manager, says that it will be a while before LEDs with this type of performance are available in the market. However, it is clear that we have demonstrated a set of innovations that will enable performance to be significantly increased in The not too distant future, says Landau.
We will be releasing new products this quarter that will begin incorporating one or more of the technologies that went into the devices with the record performance.
The light output performance announced by Philips Lumileds is 17 times greater at the same power than was available in 1999 when the company introduced the first high-power LED. While performance numbers continue to increase for low power LEDs, operating at lower currents such as 20mA , high-power LEDs are required to deliver the quality and quantity of light required for today's and tomorrow's lighting applications. 
The oil resistance of this type of cable makes it ideal for use in industrial environments where there is a high risk of exposure to oil or other similar substances. It can be used in applications such as oil refineries, chemical plants, and automotive manufacturing facilities.
The PUR sheath also provides excellent mechanical protection, making the cable highly durable and resistant to damage from impacts or abrasion. This makes it suitable for use in harsh environments where the cable may be subjected to heavy use or rough handling.
In addition to its oil resistance, PUR sheathed cable often has other desirable properties such as flame resistance, UV resistance, and flexibility. These properties make it a versatile choice for a wide range of applications where durability and reliability are important.
Overall, PUR cable is a reliable and durable option for applications that require protection against oil and other petroleum-based substances. Its ability to withstand harsh environments and resist damage makes it a popular choice in various industries.
New results from Lumileds indicate an output of 136 lm at 350 mA for white LEDs, corresponding to 115 lm/W efficacy. Philips Lumileds has claimed new performance records for high-power white LEDs with efficacies well in excess of 100 lm/W. The Company expects that the enabling technologies behind these laboratory demonstrations will make their way into new and existing products, beginning in the current quarter.
