If you're lighting a living room, bedroom or kitchen, achieving a smooth dimming to a low light level is essential. While most dimmer and LED lamp combinations will work out of the box, setting the low-end cut off point can make a huge difference.
When adjusting the low-end cut-off, you are stopping the lamp going into an unstable state e.g. flickering. You can also prevent the lamp from going out as you turn down the control knob. You may also find that you enable the lamp to dim to a lower level.
Every lamp is our test setup was different and required some dimmer adjustments to eliminate low end flickering or expand the lighting level range. The method to set the low-end cut off differs between dimmer manufacturers. Some dimmers have a small potentiometer on the wiring side. Others have a set-up mode accessed by turning and pressing the control knob in a specific sequence.
