I also prefer the LH351D. The LH351D 5000k looks like what was described above, kind of white creamish. the LH351D 4000k looks somewhat yellow. Shave the LH351D 5000k 90cri and something magic happens. Better tint something in between the two (around 4300k), tighter hotspot, with a touch of rosiness, you got a winner, at least for me. It’s my favorite emitter swap. I only wish I had bought more when Arrow was selling them for $0.74 each with free overnight shipping. :frowning:
