Philips 2x1200mm TL high CRI in luminaire

Posted by Marcel van der Steen in Uncategorized No Comments »

This article reports of a measurement of two FLs of 1200 mm in a luminaire. In this article many interesting lamp parameter results are presented as well as an Eulumdat file. The tubes used here are high CRI tubes, which at the cost of a high color rendering capability deliver light less efficiently.

There has been done a second measurement of these tubes in the luminaire, when the tubes have burned 100 hours, which is normally requested as a burn-in period. For the tube received here, it was not sure whether these have been burned-in before these were measured.

Anyway,  second measurement was done after 100 hours and the results remained the same. So they might have been burned in already, or the burn-in did not have any effect at all.
