Test duration and test environment<\/h3>\n

The lamp went into endurance test on 17 Oct 2009 and the test lasted until 29 June 2010.<\/p>\n

During this period of time the lamp has seen the following ambient temperature and ambient relative humidity (T and RH measurements were only started from Jan 2010).<\/p>\n

\"screen-shot-2010-08-12-at-233736\"<\/a><\/p>\n

Period 10 Jan 2010 – 3 May 2010<\/em><\/p>\n

\"14mei2010-24juni2010\"<\/a><\/p>\n

Period 14 May 2010 – 24 June 2010<\/em><\/p>\n

The ambient temperature close to the lamp varied between 9 – 33 deg C and the relative humidity between 25 – 58 %.<\/p>\n

Variation of lamp parameters<\/h3>\n

See the explanation on the OliNo site<\/a> for more on the test method.<\/p>\n

An extrapolation is done to get to the 70 % illuminance value. The illuminance value straight underneath the lamp is expected to be the good indicator of the total luminous flux. When this illuminance drops with 30 % then the luminous flux is expected to drop as well with 30 %. The assumption is here that the beam anlge and the radiation diagram remains the same. This has been checked, see also the initial table.<\/p>\n

See the explanation on the OliNo site<\/a> for more explanation and the link to the ASSIST document for the method of extrapolation.<\/p>\n

The result is 15,000 hours before the L70 is reached.<\/p>\n

Color change<\/h3>\n

The color change (change in color coordinates) is measured during the test period.<\/p>\n

Change in color coordinates during the endurance test.<\/em><\/p>\n

The color coordinates indicated with the red cross-hairs are the coordinates after 1000 burn hours. These are taken as reference. All measured color coordinates fall well within the 4 step Mac Adams ellipse.<\/p>\n","protected":false},"excerpt":{"rendered":"
