This can cause the LEDs to overheat or not function properly. In my experience, the controller I use has a minimum current setting that is suitable for most standard LEDs. However, I understand that some users may have specific requirements that the controller doesn’t fully meet. If you’re using low-current LEDs, it’s important to check the controller’s minimum current setting to ensure it’s compatible. Some controllers allow for lower current settings, which may be more suitable for sensitive LED applications. I recommend checking the controller’s specifications before purchasing and, if possible, testing it with your LEDs to ensure compatibility. If the minimum current is too high, you may need to look for a controller with a lower current range or consider using a current-limiting resistor.
