Frequently Asked Questions
Can the XLC-40-H-BS be used for dimmable LED downlights in hospitality or restaurant lighting?
Yes. The XLC-40-H-BS supports 3-in-1 dimming and delivers a flicker-free constant current of 1050mA at up to 40W. The strain-relief feature on the cable entry adds mechanical robustness for installations subject to vibration or physical handling during maintenance.
What does the strain-relief feature on the XLC-40-H-BS mean for fixture assembly?
The strain-relief (-S suffix) provides a mechanical cable anchor at the driver's wire entry points, reducing stress on internal internal connections when cables are pulled or repositioned. This makes it suitable for luminaire assemblies where cable management during production or servicing is a concern.
Is the XLC-40-H-BS suitable for powering small LED arrays in architectural cove lighting?
Yes. With a 40W constant current output at 1050mA and a CC voltage range of 9–54V, it can drive series LED arrays used in cove or indirect lighting profiles. It is specified for built-in use and must be housed inside the luminaire or architectural channel.
How is output current adjusted on the XLC-40-H-BS?
Current is set using the onboard dip switch, with an adjustment range of 0.6A to 1.4A. Strain-relief does not affect the current-setting method; it is purely a mechanical feature of the cable termination.
How many LEDs can I drive with the XLC-40-H-BS?
The constant current output voltage range is 9–54V. The number of LEDs in a series string is not fixed — it depends on each LED's forward voltage. Size your string so the combined Vf at your chosen current falls within 9–54V and the total power remains at or below 40W.
Is the XLC-40-H-BS rated for outdoor use?
No IP rating is specified for this model, and it is listed for built-in use only. It must be installed inside a luminaire or enclosure that provides the required environmental protection for the installation location.
