A brighter idea?

A brighter idea?

Being the responsible human that I am, I purchased some LED bulbs to cut my carbon footprint.

Not only have I removed much of my ‘footprint due to COVID and hardly ever leaving the house but, I am responsible with my use of resources.

The question is, how much Green can we afford?

After the incandescent bulb stopped, I replaced it with this beautiful LED bulb from LEDMEDTRICS.

Before the twenty-minute mark was up, the bulb ceased to function.

The bulb was in a standard non-dimmable lamp socket in a desk lamp.  Many are unaware that you must purchase ‘dimmable’ LED bulbs for circuits with dimmers.  I am.

If you follow me, you are aware that my curiosity knows few boundaries.

My first instinct was to contact the manufacturer.  Ooops, cannot find them.

On eBay, I can find their product but as far as the company, no dice.  Now I must tell you that twist pointed my mind in a different direction.

Removing the defective bulb (infant mortality), I noticed it was hot as any incandescent bulb ever was.

These things are assembled in such a way there is no disassembling them with the idea you are going to put them back together and use them again.

Saving a long drawn out discussion on what failed, it was a cold solder joint from the mainboard to the LED panel.  As it heated up, the contact let loose.

“Is it worth $12?”

The circuit is pretty straightforward.  We don’t know what the semiconductor is on the aluminum led substrate.

I would guess that the high tin content of the solder is most probably the reason for the cold solder joint.

For your amusement, I have taken some pictures of what is inside one of these bulbs. 

There appears to be aluminum bonded to the PVC at the base of the bulb.
