LED Lights

Posted on October 5, 2012

I found a novel gooseneck lamp at the hardware store that clamps on an edge and contains 24 Light Emitting Diodes in what resembles a stainless steel shower head.

I found a novel gooseneck lamp at the hardware store that clamps on an edge and contains 24 Light Emitting Diodes in what resembles a stainless steel shower head.

It provides very great light, but after a minute or so starts flickering like a fireplace and might cause someone to have an epileptic seizure.

Of course if I return it there could be an exchange or a refund, but I looked inside and got interested in possibly fixing it myself.

There is a wall wart power transformer at the end of the cable, and the power is distributed to the lights via about four tiny surface contact resistors, unless they’re capacitors…. I haven’t yet drawn the circuit, but I thought I spotted some cold solder points and after touching them up expected it to be fixed, but it flickered like a gambling table in Las Vegas.

What should I try?
