Frequently Asked Questions

Can I use the LDB-350L for higher-current LED downlights?

Yes, this model is intended for constant current LED loads at 350mA, which can suit downlight modules that need more current than a 300mA driver. It supports a 2-40V CC range with 14W output power.

Is the LDB-350L suitable for small outdoor LED arrays?

It can be used for small outdoor LED arrays when the array is designed for 350mA constant current operation and fits within the 2-40V range. The IP67 waterproof rating and -40°C to +71°C operating range support exposed environments.

Can the LDB-350L be used for rugged signage module applications?

Yes, it is an IP67 waterproof constant current driver, so it fits signage module applications where moisture resistance matters and the LED load matches the driver output. Its buck-boost design also supports the listed 9-36VAC input range.

Would the LDB-350L work in compact LED products where space is limited?

Yes, this is a compact driver at 31.8 × 20.3 × 12.2 mm and 0.02 kg, which helps in small LED product housings. It is still a constant current driver, so the LED load must be matched electrically rather than treated like a constant voltage device.

How do I know whether my LEDs will work with the LDB-350L?

The driver outputs constant current at 350mA, so compatibility depends on whether the LEDs are meant for constant current operation. Its CC output voltage range is 2-40V, and the number of LEDs depends on the forward voltage of each LED.

How does the LDB-350L compare with other LDB series drivers?

According to the sibling list, LDB-300L and LDB-300LW are 300mA, 2-40V, 12W; LDB-350LW matches this model at 350mA, 2-40V, 14W; LDB-500L and LDB-500LW are 500mA, 2-32V, 16W; and LDB-600L and LDB-600LW are 600mA, 2-30V, 18W. The LDB-350L is the pin style 350mA version with 14W output.
