Thanks McTimson

The red thing is another form of capacitor.

Here's what I know so far. the 4 diodes and 1 capacitor are a bridge rectifier. they convert the AC into DC since LED's are DC only.

the Resistors control current. I am not sure what the second capacitor does. the unit is wired in series.

the LED's appear fine. for the second that they light up they light up properly. Its not a matter of voltage. even if I ran 25% of the needed voltage they would still illuminate just not a brightly. This is how I fixed my "tube" led fixtures that were running too hot. Lowered the voltage to 80volts with a variac so that they would consume fewer watts and therefore stop overheating.
