I have 6 Royal Blue LEDs from back in 2012 from Rapid LED and I just purchased 6 XP-E Blue and plan to run them in series. My brain hurts and I just want an answer. LOL. I've always just run each color on it's own driver. Were the Royal Blue back then from RapidLED XP-E? XP-G? I planned on running them on a single Mean Well ELN-60-48D. Does it even matter if the forward voltages vary when running LED's in series so long as you don't exceed the amperage for a particular LED type.
