![]() One of the main reasons dimmers have maximum loads is because of the inrush current caused by LED drivers. Surpassing these limits can result in premature dimmer failure, flickering due to noise, as well as breaker tripping. The LED minimum load rating for LED load dimmers is usually given in number of lamps instead of Watts (W) or Volt Amps (VA).ĭimmers also have maximum load requirements to ensure the load does not exceed the dimmer’s design limits. Dimmers that are designed for LED loads usually have a lower minimum load requirement and typically only require one or two fixtures. Testing is necessary to determine the exact number of LED fixtures needed for each incandescent dimmer. This means that these dimmers will most likely require multiple LED fixtures to meet the minimum load requirement. This behavior can include flickering, reduced dimming range, flashing when off, or not even working at all.ĭimmers that are designed for incandescent loads tend to have a larger minimum load requirement because incandescent fixtures generally have higher wattages than LED fixtures. Two of these requirements are minimum and maximum loads.ĭimmers have minimum load requirements because if the LED load isn’t drawing enough current to keep the dimmer’s switching elements closed, the dimmer will have unpredictable behavior. The dimmer you have has several electrical requirements that must be met in order to ensure proper performance. ![]() This is because compatibility is just one part of the dimming puzzle. ![]() When it comes time to test out the performance, you’re not seeing what you were expecting. You have done your research and confirmed that the dimmer you have just purchased is compatible with your LED fixtures. Lighting and Controls Applications Engineer
