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

The lamp went into endurance test begin April 2010 and ended on mid Jan 2013.<\/p>\n

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

 <\/p>\n

Period 15 April 2010 – 17 Jan 2013.
\n<\/em><\/p>\n

 <\/p>\n

 <\/p>\n

The ambient temperature close to the lamp varied between 6-31 deg C and the relative humidity between 30-80 %.<\/p>\n

Variation of lamp parameters<\/h3>\n

\"\"<\/a><\/p>\n

The variation of the lamp parameters during the endurance test.<\/em><\/p>\n

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

The power and the illuminance decrease slowly. Herewith the lamp parameters of each lamp separately.<\/p>\n

\"\"<\/a>\"\"<\/a>\"\"<\/a><\/p>\n

An extrapolation to 70 % illuminance level can be done. The decrease in illuminance value is taken as a measure for the lumen depreciation. This is valid as the beam angle is not changed.<\/p>\n

\"\"<\/a><\/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 is 32,000 hours for the L70 level (70 %) after 6,000 hours of testing.<\/p>\n

The result is 52,000 hours for the L70 level (70 %) after 25,500 hours of testing.<\/p>\n

Herewith the results of each lamp sepately.<\/p>\n

Lifetime results of each lamp separately.<\/em><\/p>\n

Each lamp separately, has the following L70 lifetimes (after 6,000 hours testing): 40,000, 27,000, 31,000 hours.<\/p>\n

Each lamp separately, has the following L70 lifetimes (after 25,500 hours testing): 66,000, 47,000 and 45,000 hours (na 25,000 hours of testing).<\/p>\n

Color change<\/h3>\n

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

The color coordinates indicated with the red cross-hairs are the coordinates after 1000 burn hours. These are taken as reference. After 25,500 hours the color point remains inside the 2-step McAdams ellipse.<\/p>\n","protected":false},"excerpt":{"rendered":"
