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

The lamp went into endurance test on 26 April 2011 and the test continues. The summary table gives the results after 10.000 hours. The graphs below give the results up to 11.500 hours (Sept 2012).<\/p>\n

During this period of time the lamp has seen the following ambient temperature and ambient relative humidity.<\/p>\n

The ambient temperature close to the lamp varied between 15-32 deg C and the relative humidity between 15-80 %.<\/p>\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 angle and the radiation diagram remains the same.<\/p>\n

Extrapolation of the illuminance.<\/em><\/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 for L70 cannot be determined as the illuminance does not decrease.<\/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. After 11.500 hours the color point remains well inside the 4-step McAdams ellipse.<\/p>\n","protected":false},"excerpt":{"rendered":"
