DESCRIPTION
• General lighting application
VLSL31 is a metal core based high brightness LED power
module, assembled with 24 HB white LEDs. VLSL31 is
natural white with a color temperature of 3800 K to 5000 K.
The module is designed for flexible use due to the option for
using special reflectors to adjust the emission
characteristics.
• Backlighting clusters for advertising boards
• Spotlight illumination for off-road vehicles
PRODUCT GROUP AND PACKAGE DATA
• Product group: LED
• Package: LED module
• Product series: power
• Angle of half intensity: ± 60°

Notes
(1) Forward voltages are tested at a current pulse duration of 1 ms and a tolerance of ± 0.1 V. Luminous flux is measured at a current pulse
duration of 25 ms and an accuracy of ± 11 %.
(2) Calculated based on single LED unit.
(3) V classes are marked at the LED cluster and represent the technical classification only. The single groups cannot be specifically ordered.
