Life Time
Notes :
1. Electrical characteristics are determined after the unit has been ‘ON’ and stable for approximately 120
minutes at 25±2°C
The specified current and power consumption are under the typical supply Input voltage 24V and Vbr 3.3V,
it is total power consumption.
The ripple voltage of the power supply input voltage is under 0.2 Vp-p.
LPL recommend Input Voltage is 24.0V ±5%.
2. Brightness Control.
This VBR Voltage control brightness.
VBR Voltage
3.3V
Function
Maximum Brightness (100%)
Minimum Brightness.(25%)
0V
3. The life is determined as the time at which luminance of the lamp is 50% compared to that of initial
value at the typical lamp current on condition of continuous operating at 25 ± 2°C.
Specified value is when lamp is aligned horizontally.
