Troubeshooting DIY LED

[HeliWrench]

Seems to me the screw head are grounding/shorting the LEDs to the heat-sink. Maybe try using smaller head screws that don't contact the terminals on the LED stars.

Let me know if this helps.

Here I pencilled in how I had the LEDs wired together before removing the wiring last night.


Here is a close up of how i have the LEDs wired. I only resoldered the first 2 LEDs together again for testing purposes and was unable to get both to fire at the same time off of a battery.

^ looks like the OP is using nylon washers so shouldn't be shorting
