I compared my low serial number (handpicked for brightness) KL4 with my brother's low serial number KL4 and mine was brighter. He got a TW4 with a KL4 serial numbered in the 5000 range. I swapped out his TW4's KL4 onto my L4 and noticed that it was considerably brighter than my own. Anyone else observe that the newer KL4s are brighter?
