The 103 watt retrofit fixture puts out plenty bright, 11,050 lumens of light. I don’t see why you’d need a 140 watt fixture.
I answer thusly. Years ago replaced (4) old 400W MH with the 320 Scottsdales at my exit. Saved 20% on electricity and it was an improvement.
Later replaced more 400W MH with 150W LED from KR. in the tunnel. Did 2 as an experiment. Saved 62% on electricity and it was an improvement so I replaced 6 more. Now, by comparison the 320W Scottsdale look like they need to be replaced.
So, yes I could save $60.00 or so per retro kit. Have the equivelent or maybe better. However, over the life of the fixtures (Hopefuly) the aded cost will be nominal and the extra utility cost will be worth it.
