Note
Note Lamp life time is defined as the time when brightness becomes 50% of the original value in the
continuous operation under the condition of Ta=25 and brightness control(VBRT=3.3V).
This definition is valid with the condition that the module is placed horizontally. (The wide side of the
module should be parallel to the ground.)
