I put together a S2+ last night using a H17f driver and Nichia 219 LED on a Sinkpad. After I soldered everything up, the light isn't working with a fresh 18650.
What should I check? The solder joints are done correctly and I even tried a different LED that I had laying around. This is my first light and I'm at a lose.
