Frequently Asked Questions

Can the LDB-500LW power a 500mA LED downlight module?

Yes, this is a constant current LED driver with a 500mA output, so it matches downlight modules rated for 500mA. The LED load still needs to remain within the 2-32V CC range and the 16W output rating.

Is the LDB-500LW suitable for illuminated sign modules or channel letters?

It can be used for signage modules or small LED arrays when the LEDs require 500mA constant current rather than constant voltage. The total LED forward voltage must stay inside the 2-32V constant current range.

Can this driver be used for a compact constant current LED array?

Yes, if the array is designed around 500mA operation and does not exceed 16W. The driver regulates current, so it is intended for constant current arrays rather than fixed-voltage LED strips.

How do I size LEDs for the LDB-500LW?

Use the 500mA output current and the 2-32V CC output range as the main sizing criteria. The exact number of LEDs depends on the forward voltage of each LED, so compatibility is based on the total LED voltage rather than a stated LED count.

Is the LDB-500LW appropriate for outdoor or sealed applications?

The IP67 Waterproof rating makes it appropriate for applications that need strong dust and water resistance. It is also rated for -40°C to +71°C operation, which supports use in challenging conditions.
