Hey all, so i'm about to buy an Liteflux LF2XT but i'm not sure if i should go with the R2 WH emitter or the Q4 4C emitter. The R2 costs an extra $15, is this even worth it? From what i can gather it seems like the increase in brightness is barely even noticeable since we're already pretty up there in the lumen range. I care about brightness and tint too so i won't just buy the brightess LED if it has bad tint. But i want it to be at least close to the best LED's brightness. Thanks!
