 LED light bulb hum

I have very slowly been adding a couple of LED bulbs to my house, starting by changing out the highest usage locations first.

So last week I got a dimmable floor lamp from Ikea and bought one of their 600 lumen bulbs. No hum with this bulb, but 600 lumens is just not powerful enough for my office. Not to be thwarted I went to Lowes and bought an Ultratech by Feit Electric bulb rated at 1600 lumens for $34 each, light temperature 3000k.

Finally the light about is pretty good, but I have gone from $10/Ikea LED bulb to $34/each. And sadly now the bulb has hum that sounds light a fluorescent bulb.

At first I thought it might be the in cord dimmer but it still hums in a regular fixture.

I will return the bulb today... who said buying the latest technology is easy, it is tough work saving energy...

 LED light bulb hum

Hi Ken,

I have swapped in other LED Bulbs and LED floods in the fixture and none of them hum and all of the bulbs come from Feit Electric (Lowes Ultratech). The bulb that hums is the most powerful I have seen so maybe that has something to do with it or as you say just a bad one that I have. I need to have the floor lamp close to my desk, otherwise it would not be so bad, but for the money I just want lots of light and no noise Smile

I am definitely returning it. I put a daylight LED flood 800 lumens in for now, but a floor lamp should have a bulb so that light radiates a bit....

Thanks Izera!

Yup it does not matter whether its GE, Sylvannia, Phillips, or private label etc. they all seem to be made in China Smile

Right now I am just trying to find a brand that works so I can order online to save bucks if and when I buy more, only replacing the lights that are on constantly at home first.

 LED light bulb hum

I returned the humming bulb and got a Par38 Daylight Flood LED 1400 lumens 120 watt equivalent uses 23 watts. Same outfit Feit Ultratech. The 5000k light for my office is much better for my office than the 1600 lumen 2700k temperature that I returned. With this light I do not need the desk lamp or the bookcase lights I have. And no noise and very little heat, the other one that hummed was quite hot...
