For the dimming to be smooth and to match up with the motion of the dimming switch, the LED driver needs to be loaded as close to the rated maximum power output as possible. The resistor eases this somewhat and gives us something in between, probably in the 200-300% power range. But they are current-hungry, and must be current limited. If there were something wrong with the first string that reduced the voltage to the next two, then all, but still just one problem. Are there any sets without a lot of fluff?

LED bulbs are very command in the household nowadays. This is rare, but if an appliance with a heavy power draw, such as an electric fan, is on the same circuit as low-power LED bulbs, it can cause flickering. That is the simple explanation, but, of course, the reality is a little more complex. Why? They don't regulate current, they just make the voltage-current curve somewhat less steep, which is "good enough" for working with one expected voltage. What tha led is going on? To learn more, see our tips on writing great answers. dumb question, but are you regularly unhooking the 18650 and putting it back on the charger to recharge?
