Happy to oblige. The 4500K is markedly cooler and rosier than it's 4000K sibling. Both are 219b, of course. Overall, the 4500K appears brighter and holds it's own next to the 5700K, although the latter takes on a funky green algae color when you cross the beams. Not recommended. I swapped out bezels and am now running a silver bezel on the 4500K, so I might have gained five or six lumens.
