Frequently Asked Questions
Can the NLDD-350HW be used for a 350mA LED downlight retrofit?
Yes, when the downlight is built for constant current operation at 350mA. The NLDD-350HW is a 60W step-down constant current driver, so it is intended for LED loads that need regulated current instead of fixed voltage.
Is this a good option for outdoor signage modules or small LED arrays?
It can be used for signage modules or small LED arrays when the LED load is rated for 350mA constant current. Its IP67 rating supports use in more exposed conditions, but the load still has to fit within the driver's 52-6V constant current range.
Can I use the NLDD-350HW in sealed or weather-exposed LED assemblies?
The IP67 rating and operating range of -40°C to +50°C make it suitable for enclosed or weather-exposed LED products within those limits. It is still a constant current step-down driver, so it should be paired with LED modules designed for constant current control.
What kind of LED load matches the NLDD-350HW?
This driver is meant for constant current LED loads, not constant voltage strips or modules. The constant current output range is 52-6V, and the actual number of LEDs depends on the forward voltage of each LED rather than a preset quantity.
What is the difference between the NLDD-350HW and the other NLDD wire-style models?
In the wire-style group, the listed siblings are NLDD-500HW at 0.5mA with 52-6V, NLDD-700HW at 0.7mA with 52-6V, NLDD-1050HW at 1.05mA with 52-6V, NLDD-1200HW at 1.2mA with 46-6V, and NLDD-1400HW at 1.4mA with 46-6V, with all shown as 60W models. The NLDD-350HW is the wire-style 350mA version in that same series.
