This is understood to be a more sporadic, infrequent symptom of bad LED dimming, occurring when the lights randomly turn on and off when paired with a dimmer control. Similar to flickering, strobing occurs when your lamps rhythmically flash at a less-frequent rate than a flicker. This symptom is understood as rapid, sporadic pulsing of your lamps when paired with dimmer switches. This symptom occurs when you've dimmed your lamps all the way down, but they continue to glow or produce small amounts of light. This symptom is present when your lamps don't respond to the adjustments you're making on the dimmer switch for certain sections of the dimming scale. This is the inverse of "drop out" and occurs when you're sliding the dimmer switch on, to increase light levels, but your LED lamps suddenly turn on at a brighter level than you would normally except. This symptom occurs when you are trying to dim the lighting down and the light suddenly cuts out before you slide to the bottom of the switch. Here's how we'd describe some of those symptoms: 1. Or your LED lamps may simply flicker or flash when paired with certain dimmer switches. Or you may have "dead areas" as you slide your dimmer switch. What we've seen over the last few years with the challenges of properly dimming LEDs are simply growing pains and, fortunately, as an industry, we appear to be past a lot of the significant problems.Ī common issue with LED dimmability is sudden turn on or turn off when you try to adjust light levels with your dimmer switch. There were issues dimming fluorescent lamps in the early days of that technology, just like LED lamps. Throughout the history of lighting, problems tend to emerge when new technology is introduced to the market. Or maybe you were previously encountering symptoms, and that's what prompted the testing.Įither way, the symptoms were probably one of the following. Maybe you encountered these symptoms during the testing process. Similar to lamps, a compatibility check at the beginning is critical to ensure success. One interesting note is that dimming is always related to the driver, which is a separate component in most fixtures and retrofit kits. To simplify the process, start with field tests, compatibility charts for the lamps or fixtures you're considering, and try multiple lamps on multiple dimmer switches. With dimming, there are advanced tests that can be done to test out the cause behind the symptoms you're experiencing, but they can be time-consuming and often require expensive equipment. If you show up at your doctor's office with a sore throat and a cough, she may just order a strep test for you, to definitively determine if strep throat is the cause of your symptoms. If there's a test you can perform, you use that to determine potential causes of the problem. We'll go over common LED dimming problem symptoms later.

(The good news is, we know a handful of cure-alls when it comes to this stuff.) Different problems share similar symptoms, making it awfully difficult to diagnose the cause. In medicine, the symptom of coughing does not always indicate that a patient has a common cold.
#HARD DISK LED CLOCK DRIVERS#
Are the drivers in my fixtures dimmable?.In a dimming scenario, start with this checklist: You start by checking vitals before looking at the symptoms of the issue. Diagnosing LED dimming issues is somewhat similar to diagnosing a sickness. Why are there still issues, even when lamps and fixtures are more reliable and dimmers more tolerant? It wasn't that long ago we were answering the question: can LED lights be dimmed? The answer is yes, but years later problems can still surface when you try to run LED lamps or fixtures on dimmer controls.
