LUXEON Rebel based downlighters from Integrated System Technologies

SAN JOSE, Ca. - Replacing recessed lights that use compact fluorescent and less efficient conventional lamps with LEDs which use less power and are more environmentally friendly became a little easier this month with new LUXEON Rebel based downlighters from Integrated System Technologies (IST) in the United Kingdom.

Two models, the DL-080 and DL-090 were designed with the specification and contracting communities in mind so that the light output and installation process would be familiar and comparable to existing conventional solutions. Payback periods are expected to be 24 - 33 months with 12 hours of daily use. Philips Lumileds has published a new case study describing the development of these products and it's available on the web at

The design and engineering parameters for the new recessed lighting were demanding. To meet the requirements, the LED had to provide:

o A very small footprint so that all the units would fit in a 34mm diameter disc.

o Superior reliability and lumen maintenance so that an extended warranty could be offered.

o Excellent efficiency so that the luminaires would be Part L compliant in the United Kingdom.
