Step 9LED Wiring
,
When inserting the LEDs remember the polarity. You can see the polarity when looking carefully in the gel head of the LED. I oriented the holes so that the even circle LEDs are oriented the same polarity and the odd circles are in reversed polarity. Consider the inner circle as even.
I put a small piece of tubing on each leg to raise the LED off the board so it could later be adjusted for focal point alignment. You could also use tiny beads or even small bits of wire insulation too.
Manage to get a good picture of the wiring job so you can get an idea from the pix and from the Dave Johnson strip light, just think round instead of straight. Most of the solder connections can be done using the LED leads (use extra bare wire as required).
Finish the wiring with two wire pigtails as shown. This makes for easier testing and assembly. Use the duct tape to cover the wiring on the back of the donut.
(You may want to jump ahead at this point and test the wiring. Remember; do not just connect 120Vac to the pigtails, as the circuit also requires the capacitor and resistor. Instead temporarily connect to the upper lamp head unit to test.)
