  LED light bulb hum

Buying latest technology for me has often proven to a waste of money. Seems one or two generation old is better buy again for me. I spent some time this week looking at options in cell phones and am about to decide sure do miss a simple phone that only makes calls.

Dennis it is my impression and understanding it is transformers that hum and not the fluorescent bulbs. On the high sodium outdoor lights not sure on all but many of them also have transformers which is normally their hum source.

I am going to guess there is a small transformer in the light you have here. Funny was looking at them in lowes yesterday afternoon. Bought compact fluorescent again. That bulb is easy large enough to have a transformer built in as the compact screw in fluorescent do. If there is a hum in a transformer not aware of any way to remove it but might be indication of voltage being my guess is low or in fluorescent maybe a fixture that needs to be mounted more secure.

Then there is the real possibility,,,you just have a bulb that has issue and needs to be replaced. kt

And heat is a sign of wasted energy in lights. Energy that is producing the heat is not producing lighting. That is of course part of the issue with some sources of lights. Thanks for the info Dennis.
