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

The lamp went into endurance test on 25 Oct 2011 until 19 July 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

The extrapolation is done with help of the illuminance measured, until the 70 % level.<\/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 extrapolation of this data until 70 % of illuminance is reached at about 20.000 hours.<\/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 6000 hours the color point goes outside the 4-step McAdams ellipse.<\/p>\n","protected":false},"excerpt":{"rendered":"
