   Not measured.

A According to the lamp manufacturer, use of the “parallel-walled” optic light guide will reduce the light intensity with about 50% compared with the 7 mm diameter light guide.
B Irradiance was measured with or without the cover part and without the disposable tip attached. The disposable tip will reduce the irradiance.
