Rectified vs. Non-Rectified LED Lights
Our expert, Randall Whitehead, IALD, explains what makes an LED rectified.
 
What are rectified and non-rectified LED lights?
From what I have read, all LED lights naturally flicker at a rate of approximately 60 Hz per second. This is known as a half wave, also called non-rectified light. This type of light is common to various holiday LED light sets and may be more easily detected if the lights are moving. (They flicker more depending on the amount of eggnog you have enjoyed.) There are flicker-free, or rectified, LED lights on the market. They turn on and off (flicker) even more rapidly than non-rectified lights, at a rate of about 120 Hz per second, which is virtually undetectable. They are more costly than non-rectified lights and are 30 to 40 percent brighter.
