Find the answer to the frequently asked LED Lights related question: Why Do LED Lights Flicker?

There appears to be a bit of confusion surrounding LED and fluorescent lights. Because of this, a lot of consumers are asking the question, “Why do LED lights flicker?” Many of us have had occasion to be subjected to those annoying fluorescent bulbs that were tucked away under ceiling panels that would flicker whenever they were nearing the end of their life spans. Fluorescent lamps also flicker as they are turned on because it takes a few moments for the gasses to heat up sufficiently to produce light. LED lights do flicker, but not in the same way, and as a matter of fact, they flicker at such a fast rate of speed that it is usually imperceptible to the human eye.

Non-Rectified Flickering LED Lights

It is a fact that all LED lights naturally flicker at a rate of approximately 60 Hz per second. Even though that is an extremely fast rate of speed, there are some individuals who can actually detect the flickering at that rate. This is known as a half wave, also called non-rectified light. This type of light is common to various Christmas LED light sets and may be more easily detected if the lights or the individual are moving. Unfortunately, this flickering in non-rectified lights is a common complaint of consumers in regards to some inexpensive Christmas lights.

LED Flicker Lights

Some LED lights are meant to flicker, as is the case of LED candle lights. These lights are designed to resemble realistic candle light that flickers naturally as a result of movement in the air around them. This flickering, or rapidly pulsing on/off current, is produced by altering the rate of Hz/second. There are also twinkling LED strands that are used to decorate around the holidays, and these two are actually produced by causing the flicker to be controlled at a lower rate so that it is discernable by the human eye.

Led light flicker is also related to the driver. If it is a good quality product, the driver uses a constant current circuit to isolate the DC voltage output. Led light is very stable and there will be no flicker.

LED lamp bead and LED drive power do not match, normal single foot 1W lamp bead withstand current, 280 to 300mA, if the lamp bead chip is not full power will cause the light source stasmotic phenomenon, the current is too high lamp bead can not withstand a light off, serious phenomenon will be the lamp bead built-in gold wire or copper wire burned off, leading to the lamp bead not bright.
