Would they not work at all when the controller is powered up tho if they was trashed and do mean putting solder to the sides of the leds meaning there might not be enough
Thanks for the reply

Actually, I have damaged a few LEDs in the past by setting my iron to 850F instead of the lower temps. They don't have to look brown or show any form of damage to be burnt from the inside out. I find the 0603 LEDs are very sensitive to overheating, so make sure you solder quickly. I'm very skilled at soldering and can make my joints look like welds if I need to and have had some success with soldering to 0603 without damaging the LED at 850F, but I have only about a half second before it burns at that temp. As said before, try redoing your solder joints and if the LED still doesn't light completely, replace it.
Soldering at 60w isn't recommended, but I have it and like using the highest temps possible. One of the workers at my dad's company thought a board I repaired was ordered in from the manufacturer. That was a good day for me
