Hello,

I am trying to fix an LED reading lamp (this one: https://www.wayfair.com/lighting/pdx/brayden-studio-barton-52-task-floor-lamp-brsd3504.html )

I've removed the LED element and was hoping to try to order a replacement somehow. It was soldered in with 2 wires. It appears to be a tiny circular PCB that is attached to a circular piece of metal which may or may not be part of the "part" I am looking for.

Any help appreciated ! See attached pic if you think you might be able to help. Thanks

My guess is that it's a white power LED on a heatsink.

Would be surprised if the LED is bad. The supporting electronics is usually the weak part, in particular caps that get fried from high temperature.

Thanks @dl324 . I should have mentioned the symptom was that it was intermittent, on/off and varying levels of brightness. Tapping the lamp anywhere would make it switch on/off or less bright/more bright.

Bond wires in LEDs can do that. I have an LED flashlight that blinks. When I turn it off and let the offendling LED cool down, it stops blinking. In my case, I know it's the LED because there's no electronics.

I have a couple CREE 60W equivalent LED bulbs that blink intermittently. Still haven't gotten around to taking one apart to see I can isolate the cause.

If you can measure the LED current and voltage, it'll give you a better idea of the power rating. If it's driven with a current source, that'll complicate things because you won't be able to measure current.
