    LED lights are flickering

    I have two jobs with flickering LED lights.
    Job 1: are 110v LED tubes. They will flicker every five minutes or so.

    Job 2: I'm using Lotus LED 110v. They will flicker about every 7 seconds.

    Has anybody else run into this problem and if so how did you fix it?

    cburke1111:

    Job 1. Does this LED tube require any type of external ballast?

    If no, then take the tube home, or shop, or any other distant point and try it there. If it flickers assume a bad tube, and try a different one.

    If no flicker, then see what is wrong with fixture, or supply voltage, at the original location.


    Job 2. Your description means nothing. I know nothing about the LED.

    Again try it in a different location.


    In both cases use a Variac to adjust input voltage from 90 up thru 140 V and see what happens at different voltages.

    Most dimmer manufacturers and most LED manufacturers have lists of compatible combinations. Check with each of them, starting with whichever would be more expensive to replace.

    Thanks for the reply.

    Job 1. I do not have a dimmer.
    Job 2. I only have a dimmer on 3 out of 13 of the lights.

    Thank you
