This document gives some specific power consumption data of IR illuminator, including that at standby state and normal working states with intensity potentiometer set at LO, 1/3 turn, 2/3 turn and HI positions.
1. The power consumption at standby state (LED OFF):
2. The power consumption & projecting distance at normal working states:
<Note>The distance was estimated roughly in proportion to the measuredpower consumption above.
