Death and Life of an LED Spotlight

The Lights Of America model 2002LEDR30-65K bulb lasted about a year of intermittent use.
Once something don't work, you can't bust it. So I introduced it to Mr Saw to see what I could find in it.
Sawing around the joint didn't get me as far as I'd have liked, so I ended up sawing off the screw-in part of the bulb. No surprise, this is attached to the bulb innards with a couple wires.
I can solve that.
Once I had the wires clipped, I could see the insides of the thing. Basicly, it's a small power supply.
A little zip cord, and I was ready to see if the power supply was working at all.
The results of this test was that the light didn't light (the problem wasn't in getting power to the power supply. I hooked up my ocilloscope to the power supply outputs that I could reach and determined that the output was a half-cycle DC voltage. I'm not sure what it was supposed to be - a half-wave is one way to make a really cheap DC power supply. We're not talking about a computer power supply here, we're just running some LEDs.

But, there's more to this thing that what I can see, so a gentle bit of persuasion

displayed the device innards. 3 wires from the power supply attach to the circuit board. The LEDs are mounted on the circuit board in sets of 8 or 10, with traces connecting the banks of LEDs that are wired in series.
Another recent death in the electronics arena was an old DSL firewall/router.
This provided a 12v 1A power supply, and an adapter that would accept the plug.

With a little testing, I decided that I could run 5 LED's off that wall wart before the LED's got dim.

Some scrap wire, some solder,

and presto -

What used to be a 60 W equivalent LED, and was then a badly-designed paperweight is now suitable for use as a night-light.

My Kill-A-Watt guage says it's drawing 0.03 A

If/When I stumble across a more-powerful wall-wart, I might decide to rework this for more working LEDs.

In the meantime, it's an oversized night-light.
