Frequently Asked Questions
Can I use the LDB-350LW for a 350mA LED downlight module?
Yes, this model is a constant current LED driver with a 350mA output, so it fits LED downlights designed for 350mA drive current. The LED load also needs to stay within the 2-40V constant current range and the 14W rating.
Is the LDB-350LW suitable for LED signage modules?
It can be used for signage modules or small LED arrays when the load is designed for constant current operation at 350mA. It is not a constant voltage driver, so it should be matched to LED modules that specify 350mA and stay within the 2-40V CC range.
Can this driver run a small custom LED array?
Yes, if the array is a constant current load rated for 350mA and its total forward voltage falls within 2-40V. The driver is rated at 14W, so the full LED load needs to remain inside that power limit.
How do I know if the LDB-350LW is compatible with my LEDs?
Match the LEDs by current first: this driver outputs 350mA constant current, not constant voltage. The LED string must operate within the 2-40V CC output range, and the number of LEDs depends on the forward voltage of each LED rather than a fixed LED count.
Is the LDB-350LW appropriate for wet or outdoor conditions?
The unit is rated IP67 Waterproof, so it is built for environments where water and dust resistance matter. It is also specified for operation from -40°C to +71°C, which supports demanding outdoor or industrial conditions.
