About 2 years ago I struggled with Lumen Comparison of LED vs. MH. The recommended equivalent LED for MH was far fewer lumans. I took a chance and bought a replacement fixture for the 400W in the Tunnel from KR. Bought the 150W (Actual) Light was better than the 400W.
Keep in mind though that metal halides lose the majority of their light output before they fail, so comparing 400W metal halides at end-of life to a 150W LED is not an accurate comparison.
