Junlebao is based in Shijiazhuang. This barn is in China.
180 legacy 200 W industrial fittings became 300 Hullray T21 fittings at 60 W. Connected load went from 36 kW to 18 kW.
Electricity is shown as $14.8 a day, $5,411 a year and $43,285 over eight years. Eight-year energy cost is $86,569 on the legacy system and $43,285 on Hullray T21.
Efficacy moved from 110 lm/W to 150 lm/W. Flicker index moved from 1.2 to below 0.4. Color temperature moved from 6500 K to 5000 K.
Feeding alley: 65 lx to 213 lx, uniformity 0.42 to 0.80.
Reported yield moved from 34 kg to 38.1 kg per cow per day, up 12% and 4.1 kg. Feed-to-milk ratio moved from 1.45 to 1.37.
A 100-cow illustration at $0.51/kg is about $209 a day, $63,745 a year over 305 days, and $509,960 over eight years. It is an illustration, not measured farm revenue.
